Dear collectors,

Here is the e-mail version of my recent mailed paper list.

CAMPO DEL CIELO, Argentina: Coarse octahedrite (IAB)
CAMPO DEL CIELO, Argentina: Coarse octahedrite (IAB). Found 1576.
I really hesitated to put these on here, as I really like to have multiple pieces of each offered item on these catalogs. However, year after year, I bump into these wonderful highly silicated pieces when I do inventory and have decided that they are too nice to keep leaving in deep storage. These are all really full of graphite, silicates, sulfides, (often in bands through the specimen) and look nothing like a typical piece of Campo. The two larger pieces are a bit wedged but could be split into thinner slices if one was so inclined. Wish I had gotten more of these when they were (briefly) available years ago (they were not particularly cheap back then either though). Again, these (unfortunately) are the ONLY pieces I have, so act fast if you want one.
1) Complete slices: Highly silicated:
a) 73.9 grams - 80mm x 50mm x 4mm - $130
b) 194.4 grams - 95mm x 70mm x 7mm - $240
c) 284.8 grams - 97mm x 80mm x 9mm - $300

NWA (8217): Ordinary chondrite (L5), S3, W2. Found 2013
NWA (8217): Ordinary chondrite (L5), S3, W2. Found 2013. Tkw = 490 grams.
This single stone was reported as being bought in Temara, Morocco in December of 2013. This is the last of the “prestudied” NWA meteorites I picked up a few years ago. These had some external or internal feature that made them look somewhat interesting (I don’t know what that was on this one – this looks pretty much like a normal moderately weathered L5 to me, both inside and out) so it was sent in for research work. This one, obviously, turned out to be common. I picked it up (as the original owner didn’t want to mess with it any further) and prepped it (cut and polished) for sale. Again, nothing special: a moderate amount of metal and sulfides visible in a medium brown matrix, just an affordable studied meteorite.
1) Slices:
a) 8.5 grams - 40mm x 15mm x 5mm - $11
b) 13.2 grams - 50mm x 25mm x 4mm - $17
c) 23.2 grams - 57mm x 30mm x 5mm - $28 – only piece this size.
d) 31.8 grams - 57mm x 44mm x 5mm - $37 – complete slice.
2) End piece:
a) 82.9 grams - 57mm x 43mm x 23mm - sold

NWA (5781): Ordinary chondrite (LL3.3)
NWA (5781): Ordinary chondrite (LL3.3). Found before February 2009. Tkw = 891 grams.
A single stone was purchased during the 2009 Tucson show. The Meteoritical Bulletin reports 2 pieces totaling 1060 grams because the find data for this stone got confused with another LL (an L/LL 3-6 breccia – now NWA 8738) that was submitted for research at the same time as this one. Regardless, cutting revealed a fantastic chondrule-rich interior. Chondrules of all sizes and many colors (along with some melt pockets) packed tightly together with virtually no visible matrix. This is fairly fresh. It doesn’t show much obvious bright metal (but I don’t think it had much to begin with) but it has a lot of sulfides, with many (if not most) of the chondrules being armored with it. I don’t have a lot of this material as I have already sold 2/3 of it. It seems to sell itself the few times I have shown collectors pieces of it in the past.
1) Slices:
a) 3.0 grams - 24mm x 14mm x 3mm - $36
b) 6.2 grams - 27mm x 27mm x 3mm - $74
c) 14.4 grams - 38mm x 27mm x 4mm - $165
d) 29.6 grams - 60mm x 47mm x 4mm - $325
e) 78.7 grams - 90mm x 50mm x 6mm - $700 – complete slice. Piece in group photo sold. This one looks very similar but is somewhat wedged (and thus priced a bit cheaper per gram than the original offered piece).

SAHARA (97096): Enstatite chondrite (EH3)
SAHARA (97096): Enstatite chondrite (EH3). Found 1997. Tkw = about 28 kilograms.
Actually, some of this was labeled Sahara (97072) when I got it (before cutting) but I am using the number that the Meteoritical Bulletin uses for all of the others being “paired to”. This is nice, fresh material. It has lots of fine-grained metal and lots of chondrules. This is a very primitive meteorite and I have seen a number of research articles on it the past few years because of this. However, I just discovered something surprising about it – it fluoresces! I had a fancy (and somewhat expensive) L.E.D. black light flashlight on my desk (a Convoy S2+). For grins I shinned it on the slices of this I was preparing to catalog. I was shocked by the results. This meteorite has lots and lots of tiny grains scattered throughout it that fluoresce a bright neon orange! Now I have something I can show the folks (I get some at EVERY show) that come in carrying a black light unit asking “what have you got that fluoresces?” (I used to have to say “nothing”).
1) Slices:
a) .70 grams - 10mm x 10mm x 2mm - $30
b) 1.6 grams - 15mm x 14mm x 2mm - $68
c) 2.6 grams - 23mm x 17mm x 2mm - $110
d) 5.0 grams - 34mm x 20mm x 2mm - $210
e) 9.1 grams - 50mm x 25mm x 2mm - $375
f) 17.2 grams - 70mm x 44mm x 2mm - $690 – nice complete slice!

NWA (8044): Achondrite (Howardite)
NWA (8044): Achondrite (Howardite). Found before February 2011. Tkw = 715 grams.
This is a case where an item turned out to be more interesting than what I thought when I bought it. I got around 30 fragments that I was told were “a weird eucrite” but looked like an old mesosiderite to me. Research work showed that this is actually a howardite with a lot of FeNi metal veins (highly weathered though) running through it. I asked if it might be a Mesosiderite but was told that it clearly is not due to its mineralogy. This is mostly pyroxene as the silicates of a mesosiderite would be but this also has areas of both basaltic and cumulate eucrite material. So now (hopefully) more work will (eventually) be done to determine the origin of the metal (likely from an iron impactor). These are all cut and polished fragments and don’t look like any other howardite I’ve ever seen.
1) Cut fragments:
a) 4.0 grams - 20mm x 14mm x 5mm - $48
b) 9.0 grams - 30mm x 20mm x 7mm - $110
c) 15.3 grams - 37mm x 30mm x 6mm - $175
d) 20.1 grams - 40mm x 34mm x 12mm - $220
e) 30.2 grams - 43mm x 32mm x 15mm - $325


VACA MUERTA, Chile: Stony-iron (Mesosiderite)
VACA MUERTA, Chile: Stony-iron (Mesosiderite). Found 1861.
These are pieces that I set aside around 20 years ago. Back then, I paid a premium for them as they are far fresher than the typical material from this find. Each of these had a flat spot ground into them to show the high fresh metal content of each piece. Cutting these revealed that they are indeed quite fresh internally and actually look like a mesosiderite should. In typical Vaca Muerta pieces, enough metal has oxidized to make them look much more like a chondrite (but then I’ve seen estimates that this stuff has been on the ground for up to 1 million years!). I can’t really call these “end pieces” (though many of them are) because of the flat spot that the original seller ground into them. This flat spot usually did not line up well for further cutting (either in half or slicing – but then these were really too small to slice) so I ended up with pieces having a sanded edge or areas of the back side polished. Anyway, these are really fresh specimens of Vaca Muerta that are rarely seen and representative of the mesosiderite type.
1) Cut fragments:
a) 8.9 grams - 30mm x 20mm x 6mm - $45
b) 13.2 grams - 25mm x 24mm x 20mm - $66
c) 19.9 grams - 45mm x 27mm x 12mm - $100
d) 31.9 grams - 47mm x 40mm x 10mm - $160 – only one this size.
e) 46.0 grams - 60mm x 32mm x 10mm - $230 – only one this size.
f) 107.7 grams - 55mm x 40mm x 14mm - $525 – has some nice eucritic inclusions.

IMPACT GLASS: Zhamanshin crater, Kazakhstan:
IMPACT GLASS: Zhamanshin crater, Kazakhstan:
I don’t think I’ve ever had or offered big hunks of an impact formed glass before – just small pieces that were single digit grams size to maybe a few 10s of grams sized. Here are some really big paperweight/ table display pieces I recently picked up. These are all obviously glass and not just dirt and rocks stuck together by a little bit of glass (which is what most impactites are structurally). This material is a swirled mix of dark gray/ black and green glass (most pieces are heavier on the green glass). These are from the roughly 1my old, 13.5km diameter Zhamanshin crater – where Irghizites (considered by many to be a type of tektite) are from (and, up till now, the only material I have had from this impact site). Most pieces are end pieces/ cut fragments but I do have a few thick slices available. Given the size of these things, US shipping on these will be around $6 to $10. Overseas, I’ll have to calculate shipping prices.
1) Cut fragments:
a) 239.5 grams - 115mm x 85mm x 20mm - SOLD
b) 281.0 grams - 100mm x 85mm x 30mm - SOLD
c) 581.2 grams - 150mm x 105mm x 30mm - SOLD
d) 766.0 grams - 150mm x 115mm x 45mm - SOLD
2) Slices:
a) 200.7 grams - 90mm x 80mm x 15mm - SOLD
b) 295.7 grams - 130mm x 80mm x 15mm - SOLD

Please note:
    I do have “group photos” of each lot of material above I can e-mail to those who want (please tell me what material you want a photo of). These contain the exact pieces cataloged under each name. I often have duplicate (well, similar sized anyway) pieces of many listed items. I generally send the first folks to order an item the largest available for the size. You can request the exact pictured piece if it is still available however.
 Shipping:  The post office has, once again, raised rates quite substantially. For small US orders $4 is now needed. Larger orders are now $6 to $14 (insurance is extra if desired – I’ll look it up if you want it). Overseas prices have gone up A LOT the past couple years. Now small overseas orders are around $13 (I’ll have to custom quote any larger items/ orders). Registration (recommended on more valuable overseas orders) is $15.
    I do have a fax machine that seems to work (but I have to answer it and manually turn it on), so overseas people can contact me that way if they must.  How ever, for overseas orders, it probably is best to go ahead and use my brmeteorites@yahoo.com e-mail.

Dear collectors,

Here is yet another selection of small, hard to get witnessed falls from an old research collection. I got these right before leaving for the Denver show and did not have time to process them until I got back. I have also added a few tiny little scraps I got at the show.

ATARRA, India: (L4), black. Fell December 23, 1920. Tkw = 1.28 kilograms.
I think I had a few much smaller crumbs of this some months ago (they would have been from the same source). This is a small part slice that has black crust along one edge. The interior is fresh and and shows metal and chondrules quite clearly.
.48 gram part slice – 7mm x 5mm x 5mm - $100  -SOLD

BILANGA, Burkina Faso: (Diogenite). Fell October 27, 1999. Tkw = 25+ kilograms.
This is some fragments (about 3mm x 3mm x 2mm) in a capsule in a small labeled plastic box.
Crumbs in a capsule - $10

HOLBROOK, Arizona: (L/LL6): Fell July 19, 1912.
This is a somewhat weathered fragment from a research collection. It appears that a substantial portion of the piece was used up in what ever work was being done on it as the label indicates that it originally weighed around 9.8 grams. The label also indicates that this piece was found November 8th, 1968. Nothing special, but interesting in its history.
2.6 gram fragment – 14mm x 11mm x 10mm - $40

MERUA, India: (H5). Fell February 2, 1945. Tkw = 71.4 kilograms.
This is a bottle that contains three fragments (two around 4mm x 3mm and one closer to 7mm x 4mm) and some dust. I recall, from an earlier offering of a few pieces of this meteorite, that all but a tiny hand full of this meteorite is tied up in museum collections.
1.2 grams fragments and dust in bottle - $100

NEWPORT, Arkansas: (Pallasite). Found 1923. Tkw = 5.6 kilograms.
This is a small cut fragment that is mostly metal but shows some bits of olivine (this was an old research collection piece and I suspect the “work” was done on the olivine from this piece). Regardless, this is a very difficult to find meteorite. I suspect that many (most?) pallasite collectors have not gotten a piece of this name yet.
.36 gram cut fragment – 10mm x 5mm x 4mm - $100  -SOLD

OURIQUE, Portugal: (H4). Fell December 28, 1998. Tkw = 20+ kilograms.
I don’t think I ever have had any of this. I know the few pieces that made into collector’s hands were quite high priced. Unfortunately, this is just a few small fragments (probably equivalent to around 3mm x 3mm x1mm or so) in a capsule. Nothing special, but a cheap way to add a “new” fall to a collection.
Small fragments in capsule - $10

PEACE RIVER, Canada: (L6). Fell March 31, 1963. Tkw = 45.76 kilograms.
These are all fragments with out crust, unfortunately. BUT then these are the only pieces I have had of this
meteorite in any form for many years. I think the piece that was in the “micro” collection I out together years ago was also a no crust fragment like these. Crust or not, this is hard material to come by.
1.0 gram fragment – 10mm x 9mm x 7mm - $30 -SOLD
1.4 gram fragment – 12mm x 11mm x 6mm - $42 -SOLD
4.8 gram fragment – 16mm x 16mm x 8mm - $140 -SOLD

ST. MICHEL, Finland: (L6). Fell July 12, 1910. Tkw = 16.452 kilograms.
This is a wedge part slice that I received just before going to Denver for the show. This has one natural edge (no crust, unfortunately). The interior though shows a really nice breccia texture with lighter mottled
tan and gray clasts in a dark gray matrix. Looks nice fo an old chopped up research specimen.
13.5 gram part slice – 40mm x 20mm x 5mm - $270  -SOLD

SHALKA, India: (Diogenite). Fell November 30, 1850.
Here is a small crumb (around 2mm x 1mm x 1mm) in a capsule in a box with a M Blood Meteorites label.
Crumb in capsule - $10

VACA MUERTA, Chile: (mesosiderite). Found 1861.
This is a small part slice that had a label (that says Vaca Muerta, 9.5 grams, Me1300) taped to it (well, now with it as the tape has torn free). The natural edge of the piece has all kinds of numbers marked/ painted on it. I can make out 255, 215. And Me 1300. I have no clue, unfortunately, what these numbers are or what old collections they might represent.
9.6 gram part slice with old numbers – 20mmx 15mm x 11mm - $50-SOLD

VIGARANO, Italy: Carbonaceous (CV3.3). Fell June 22, 1910.
Here is a sample of the meteorites that give the CVs the V in their type name. This is bottle (with an old label) that contains one large fragment a couple smaller and a bit of dust.
.36 grams of fragments and dust in bottle - $50 -SOLD

Dear Collectors,

I think this is my last “after Tucson” list. Now I’ll have to dig around to come up with new future offerings (I need to get a mailed list pulled together soon as well – it’ll be a busy couple weeks ahead). This is going out a bit later than I would have liked as I went to Montrose (and took longer than expected) to look at some potential meteorites (none were, unfortunately) and buy an old broken pocket watch. I will try to keep on top of e-mails this afternoon but there may be a couple issues. First, I do have some people coming over later (mine and Blake’s birthday – now over the hill at 50 even) so I may not get to check as often as usual. In addition we have ferocious winds right now. High winds like this, for some reason, often knock out our internet/ DSL connection. Strange, I thought it was all wires in the ground. Anyway, I’ll do my best to keep checking (the phone should always work, though we lost power and phone for an hour or so a few days ago during a wind storm as well).

DHOFAR (1286), Oman: (Eucrite), polymict breccia. Found December 2005. Tkw = 848 grams.
Two pieces that fit together were found about 30 meters apart. This meteorite contains clasts/ fragments of various compositions and colors – making it look very much like a howardite. However, this lacked enough pyroxene to be classified as a howardite. I recently sold out of what I had of this meteorite (and tossed out the remaining info cards) but then picked up a few more pieces in Tucson (and re-made new cards).
a)       2.0 gram slice – 20mm x 17mm x 2.5mm - $25
b)       4.2 gram slice – 42mm x 20mm x 2mm - $50
c)       6.8 gram slice – 35mm x 25mm x 3mm - $75
d)       20.2 gram end piece – 40mm x 20mm x 16mm - $200

IMILAC, Chile: Stony-iron (Pallasite). Found 1822.
This is a beautiful ¼ slice (2 cut edges at right angle to each other with the remainder being a long natural edge). This is cut super thin so light passes through all of the crystals. This fantastic material has gotten hard (and expensive) to acquire these days. I think this is the first thin slice of Imilac I have had in several years or more. A simply stunning display piece.
                22.9 gram part slice – 55mm x 55mm x 1.5mm - sold

NWA (769): (Eucrite), unbrecciated. Found November 10, 2000. Tkw = 712 grams.
I don’t think I have ever had any pieces of this meteorite before. I got a small lot of fragments, cut fragments and a couple slices at the show. Most of this does indeed look very similar in texture to typical Millbillillie but with much smaller crystal size (really fine-grained). However, a couple pieces do show some uniform (pretty much no crystal texture visible) light gray clasts. Most of the fragments and cut fragments have some (some pieces quite a lot) of nice dark crust that has not had its texture wind-polished away.
a)       2.0 gram slice – 20mm x 10mm x 4mm - $25
b)       3.9 gram fragment – 20mm x 15mm x 10mm - $49 – 12mm x 15mm crust.
c)       5.4 gram slice – 30mm x 18mm x 5mm - $67
d)       10.9 gram end piece – 23mm x 15mm x 17mm - $135 – back ~ 35% crust.
e)       15.8 gram end piece – 35mm x 17mm x 16mm - $195 – back 40%+ crusted.
f)        38.0 gram end piece – 55mm x 30mm x 17mm - $450 – back over 50% crusted.

NWA (7325): Ungrouped achondrite. Found 2012. Tkw = 345+ grams.
This is the stuff that showed weird green fusion crust on the rare pieces that had crust. Its low iron content, texture and other features have led some to believe that this may be from the planet Mercury (though others would argue that this material is far too ancient to be from a body of that size). Regardless, this is strange and unique material no matter where it came from. I have a few cut pieces and one fragment (that actually does have a small 3mm x 2mm patch of the weird green crust) that I picked up from Matt in Denver back in December but only recently got around to cataloging them.
                a) .61 gram slice – 18mm x 10mm x 1mm - $580
                b) .87 gram end piece – 14mm x 10mm x 4mm - $785
                c) 1.54 gram fragment – 13mm x 12mm x 7mm - $1400 – has small patch of     crust.
                d) 1.68 gram slice – 28mm x 16mm x 1mm - $1590

NWA 8159: Martian. Augite basalt. Found 2013. Tkw = 149.4 grams.
This is one that brings up mixed emotions for me. I am thrilled at its discovery as I am the one that pretty much discovered this gem. It was in the “likely junk to go out to the rock garden” pile that a fellow meteorite dealer had at the 2013 Denver Show. He had me going through MANY (easily over 100) rocks to see what might be important (with the rain and flooding during the show, I had plenty of time for this and found it, at times, to be an interesting distraction). I saw this one in the “junk” pile and commented that it most definitely was a meteorite as it had clearly visible shock veins. Thankfully, he had cut the thing so I had a cut surface to run the XRF on. I expected the thing to come up as a Eucrite, as that is pretty much what the thing looked like. HOWEVER, the chemistry of the thing came up as MARTIAN! At that point, the owner said that if this turned out to be the case he would give me “a complete slice of like 20grams” (gads, I wish I had gotten THAT in writing now). Anyway, not only did this thing turn out to be Martian, it turned out to be a completely new type of Martian! It has some similarities to various features of Nakhlites and Shegottites but yet is overall different. I did indeed get a package from the owner containing a sample for my helping in the discovery once this was officially reported. It contained a 2.2g block. I double/ triple checked the box to be sure I didn’t miss anything else in the packing material. Nope, nothing. I figured more would come later after cutting. I checked the Meteoritical Bulletin report for the thing and it did list me as having some of this (but unfortunately not anything about my part in the discovery) and it did indeed confirm that my share was indeed 2.2 grams. Now don't get me wrong, I am thrilled to have this (certainly better than NOTHING which is easily what I could have ended up with). I guess I am being a little greedy myself. A couple grams certainly will change my month, but 20grams would have changed my year (but then, I would have found it really difficult to break up a complete slice). I split the thick block into two thinner slices and then broke those up into the pieces listed here. I have already sold some and am keeping a small piece for myself so I have less than 1.25 grams total to sell.  The price is going to seem really high BUT this is right about what much larger pieces were selling (and pieces were indeed selling) for per gram in Tucson. The price has supposedly been raised (right after the show) to $8159/ gram. Given what the other unique Mars rock “Black Beauty” has been bringing, this is probably not all that unreasonable or surprising. Anyway, get em while I got em. I’ll give the contact info for the holder of the main portion of this material if I run out or you really need something bigger than I have here. All of these pieces are in a membrane box.
a)       .042 gram slice – 3mm x 3mm x 2mm - sold
b)       .080 gram slice – 4mm x 4mm x 2mm - $420
c)       .115 gram slice – 6mm x 4mm x 2mm - sold
d)       .335 gram slice – 9mm x 7mm x 2mm - sold
e)       .580 gram slice – 11mm x 9.5mm x 2mm - $2900

SMARA, Western Sahara. Achondrite (Eucrite), polymict breccia. Found 2000. Tkw = 12.87 kilograms.
Here is a eucrite that came from the NWA area but has an actual name and known find location. In addition, this is interesting in that it is a breccia containing clasts of many types (including subophitic basalts, granular microgabbros and impact melt clasts). I have two piece that were once one; a long part slice that I managed to break (not intentionally however) during transport back home from the show.
                19.0 gram part slice – 35mm x 34mm x 6mm - $230
                25.1 gram part slice – 45mm x 35mm x 6mm - $300

SPRING WATER, Canada: Stony-iron (Pallasite). Found 1931.
Here is a fairly small block that I have left exactly as I got it. It is a piece that is cut on all sides. It has not been polished or coated but yet still shows bright metal (with no distinct rusting) and nice bright crystals. I think that this was an old research work piece as it is in a research type snap lid plastic vial. This also has the number 135d written on it in black ink (a big part o the reason I left this thing alone – handling while polishing or the spray coating material could have easily destroyed this feature) indicating that this was likely cut from the early Nininger Spring water specimen.
                11.67 gram block – 17mm x 14mm x 12mm - $250

VACA MUERTA, Chile: Stony-iron (Mesosiderite). Found 1861.
This is a small cut fragment that came in as part of a collection. It is nothing special but the small (17mm x 11mm) cut face does show more metal than most Vaca pieces I have had.

                8.0 gram cut fragment – 18mm x 13mm x 14mm - $24
