April 29, 2014

Dear Collectors,
                Here is the e-mail version of my  “spring, after Tucson ” mailed list (just now reaching . Most of this is stuff I’ve had but finally got through research (some, like the LL3.10 below took several tries to finally get done). The hexahedrite (NWA 8302) and Fukang I picked up in Tucson and was thrilled to get them. I am keeping a full slice of the hexahedrite in my collection as it will be the first iron I have that shows a heat alteration rim. I am hanging on to a piece of many of the other things as well, as several of these are things I’ll probably never get as nice an example of (or any) again (L-melt, LL3.10, Eucrite breccia…..)

I should probably note (and should have on the mailed version as well) that many of you, as I, have not received your tax refund. If this is your case and you are interested in things offered here, I’ll be happy to set things aside for you until the IRS sends your refund. So, don’t hesitate to ask me to set things aside. This is actually the case with ANY of my offerings any time of the year. I just ask that, if things change, to let me know if you have changed your mind so I can move the item on to the next interested party.

NWA (8302): Morocco. Iron. Hexahedrite  (IIAB). Found before 2010. Tkw = 22.4 kilograms(?).
I put a question on the TKW as the official report is the 22,4kg and the small card I got when I bought the stuff said it was 15.25kilograms total. Either way, this is a nice, interesting meteorite. It shows a good number of Nuemann lines as a hexahedrite should, as well as lots of small sulfide inclusions. However, this also shows a very distinct re-crystallized heat-alteration rim along the outer edge. I have seen pictures of this in iron meteorites but I don’t recall ever having had an iron before that shows this feature. I picked the full slices as they have the clearest heat rim. The cut pieces all also show natural edge with an alteration zone.
1) Slices: etched one side:
a) 26.5 grams - 36mm x 22mm x 4mm - $65
b) 46.8 grams - 46mm x 35mm x 4mm - sold
c) 135.7 grams - 97mm x 42mm x 4mm - sold
d) 238.7 grams – 170mm x 50mm x 4mm - sold
e) 275.9 grams - 180mm x 70mm x 4mm - $600 – complete slice, really strong heat rim.
Note: I may end up cutting up the complete slice if it does not sell as is. Let me know what size smaller piece you might like and I’ll try to end up with something close to that size if I do cut this.

NWA (7019): Ordinary chondrite. L-Melt rock. Found before February 2011. Tkw = 1315.8 grams.
I got three fragments (two of which fit together) from a dealer in Tucson. It had a weird green color and an odd texture that showed some fairly large vesicles. This made both the seller and I suspect that this was an impact melt. The interior upon cutting supported this hypothesis and later research work confirmed it. The interior shows no chondrules, vesicles and rounded metal/ sulfide inclusions in a fine-grained green matrix. This highly shocked meteorite likely formed by a nearby impact that was large enough to completely melt this material before it escaped its parent body.
1)       Slices:
a) 4.0 grams - 18mm x 15mm x 4mm - $24
b) 7.5 grams - 25mm x 24mm x 4mm - $45
c) 14.4 grams - 45mm x 25mm x 4mm - $85
d) 27.7 grams - 70mm x 40mm x 4mm - $160 – complete slice.
e) 42.4 grams - 75mm x 50mm x 4mm - $240 – complete slice.
2)       End pieces:
a) 34.9 grams - 50mm x 38mm x 14mm - sold
b) 48.8 grams - 45mm x 38mm x 17mm - $245
c) 69.5 grams - 60mm x 37mm x 20mm - $345 – Main mass.   

NWA (7029): Ordinary chondrite (LL3.10). Found before September 2009. Tkw = 205.6 grams.
When I heard the news that this was a 3.10 I didn’t get too excited. BUT when I looked up just how rare such a thing is I began wishing it didn’t, more or less, take three tries to finally get this thing classified (giving up around 25 grams on each try). Currently there are only four LL3.10 meteorites known (including this one) and only another 6 classified at lower metamorphic grades (including Antarctic recoveries). If you include all the Hs and Ls (the rest of the “ordinary chondrites”) then you have another 16 meteorites known with this low or lower of a metamorphic level. Needles to say, these silces show LOTS of chondrules. Also needles to say, I have very little of this special material. I have under 100 grams TOTAL remaining.
1)       Slices:
a) 1.0 grams - 13mm x 12mm x 2mm - $50
b) 2.0 grams - 26mm x 12mm x 2mm - $100
c) 4.0 grams - 26mm x 20mm x 2mm - $200
d) 7.8 grams - 36mm x 25mm x 3mm - $400 – complete slice, lots of interesting inclusions.

NWA (7902): Ordinary chondrite (L3.7), W2. Found before February 2013. Tkw = 2.02 kilograms.
This is one I bought in Tucson last year. The seller, rightfully it turns out, thought this was a type 3 as it shows quite a lot of chondrules on the exterior surfaces. I wasn’t so sure, or at least wasn’t willing to pay the big premium that was being asked on this “type 3” (something like $3/g I think – pretty typical asking price these days for a raw “out of the field” type 3). We eventually came to an agreement we both could live with and one where I can offer this now proven type 3 for substantially less than its starting price from the seller. The interior does not show much metal (pretty much just sulfides) but is nice in texture. There are lots of chondrules of many sizes clearly visible on this roughly 55mm x 35mm cut face. The rest of the stone is
natural wind-polished crust and some fracture (secondary crust?). Nice as it is or great for cutting into slices (which I will likely do if this does not sell intact).
                1954.0 gram main mass – 170mm x 95mm x 70mm - $4000 

NWA (7252): Carbonaceous chondrite (CK5). Found before Feb. 2007. Tkw = 276.1 grams.
This is a piece that I sold after I had sent pieces off for the classification work. After several years it became clear that this was not going to get done so the buyer sold it back to me. More material sent off and the work got done this time. This was originally an individual that was completely crusted but had about 30% secondary crust (so there is likely at least one more related piece out there somewhere). I went ahead and cut the thing up. Slices of this, like most CKs, do not show a lot of chondrules (CKs average only around 15% chondrules in volume) but has an interesting greenish gray matrix.
1)       Slices:
a) 1.2 grams - 15mm x 9mm x 3mm - $18
b) 2.7 grams - 22mm x 13mm x 3mm - $40
c) 4.5 grams - 22mm x 20mm x 3mm - $67
d) 9.4 grams - 38mm x 27mm x 3mm - $140
e) 21.5 grams - 47mm x 43mm x 4mm - $300 – complete slice.

NWA (8162): Achondrite. (Eucrite, monomict breccia. Found before September 2013. Tkw = 297.4 grams.
This is one I wish I could have gotten more of. This showed some brecciation on its natural surface. The inside after cutting makes one say “wow”. This shows LOTS of lighter colored clasts of all sizes surrounded by dark highly shocked material. The material in the clasts and the surrounding matrix all have the same composition, making this a “monomict” breccia. This texture is likely due to impacts nearby on the surface of Vesta (yep, the Dawn mission data is finally getting out and it confirms that Vesta is the source for most of the meteorites classiied as HEDs in our collections!). I had this professionally cut (I hair too big for my saw) and highly polished on one side to really bring out the best in this stone.
1)       Slices:
a) .6 grams - 12mm x 10mm x 2mm - sold
b) 1.3 grams - 19mm x 11mm x 2mm - $32
c) 2.4 grams - 23mm x 17mm x 2mm - $60
d) 5.1 grams - 29mm x 27mm x 2mm - $120
e) 9.9 grams - 40mm x 40mm x 2mm - $225 – complete slice.
f) 23.5 grams - 70mm x 58mm x 2mm - $500 – complete slice.

FUKANG, China: (Pallasite). Found 2000. TKW = 1003 kilograms.
This is one that I offered (as a larger slice) on a recent e-mail offering. I picked this up as part of a collection I purchased from a German fossil dealer as a 100 gram square slice. It had never been coated so there were a couple small rust spots on it. In my attempt to put a new shine on this (using my antiquated polishing equipment) I managed to break it into several pieces – the ones listed here. All of these are still large enough to show the texture of this beautiful meteorite with its huge olivine crystals.
1)       Slices:
a) 18.9 grams - 60mm x 30mm x 2mm - $280
b) 26.4 grams - 60mm x 43mm x 2mm - sold
c) 53.7 grams - 89mm x 50mm x 2mm - sold

ACASTA GNEISS: Ancient rock from Acasta River, Canada.
Here is something I picked up a piece of a few years ago and, when I mentioned it, I found there was a big demand for the stuff (my piece got whittled down quite a bit in supplying pieces to people). I finally got some more this past Tucson. These are small 15mmx 20mm or so) pieces mounted in a labeled perky box. This material is, at this point, the oldest known rock in the world. At 4.2 Billion years old this is not quite as old as most meteorites but formed surprisingly early in Earth’s history.
                Small (15mm plus) fragment in perky box – sold out. Will try to get more.   

Please note:
 The post office keeps increasing shipping rates (despite the government’s official claim is that there is no inflation).  For small US orders $3 should still be fine for now. Larger orders are now $12 (insurance is extra if desired – I’ll look it up if you want it). The real increases came in overseas (or even Canada) shipping. These prices pretty much doubled from what they were a couple years ago. Now small overseas orders are around $9 (I’ll have to custom quote any larger items/ orders). Thankfully, it seems that the rate for registration (recommended on more valuable overseas orders) is still around $12.

                My fax machine has pretty much blown up on me. I can nurse it to work if I must (but often loose the incoming fax if I am not really careful). For overseas orders, it probably is best to go ahead and use my brmeteorites@yahoo.com e-mail. I generally get/ deal with phone calls quicker but I will try to keep up on checking e-mail this time.

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
