LIST 259 - March 7, 2023
Dear Collectors:
Here is another “after Tucson” offering. Once again, this is a list of some of the things that came home with me from the show. Some (most) of these are consignments (many brought to me during the show) and some are things I had picked up earlier.
AGOUDAL, Morocco: Iron meteorite, Coarsest octahedrite (IIAB). Found 2000.
I remember when pieces of this stuff first started coming out. They were only quite small ones (a few grams up to, maybe, a few tens of grams). The stuff was being offered as a “new Hexahedrite” (and, yes, if you only have a small piece, you are basically looking at a single Kamacite crystal, which is basically what a Hexahedrite is) for around $5 to $6/g I think. I recognized right away that the things looked like they were from a crater type impact/ fall. Yep, that is indeed what things turned out to be. LOTS of these little pieces started pouring out. Prices got quite affordable on this material (I think, for some time, I was selling it at $.50 to $.60/g). Well, like everything else in our lives these days, prices are going up (part of this is, like other meteorite localities, the find area of this material has been pretty much complexly worked over) and my cost now starts at $1/g for small pieces (in larger volumes – like 5+kg). Of all the quantity of this meteorite that was found, VERY few were of larger size (like over a kilo or so) and only a couple were “really big” (in this case, really big means around soccer ball sized or so). I know of one of these larger pieces that was cut into slices. I had heard that some of these slices were going to be available in Tucson one year. I went to the person that had them but, as they were still unpacking for the show, they could not locate them at that moment. By the time I got word that they had been found and could make it over to buy some, they were already all gone. Here, I believe, are two slices from that batch that someone faster than me was able to acquire. These are nice complete slices. Though the price is somewhat higher than they would have been back then, it is NOT by much. So, if you want a nice complete slice of this meteorite that now has a known crater associated with it (that is of yet to be determined diameter but it looks to be around 105 thousand years old), act fast, these are all I (and my source) has of these.
a) 294.0 gram complete slice – 130mm x 80mm x 4mm - $600
b) 928.4 gram complete slice – 180mm x 130mm x 5mm - $1900

AUSTRALITES: Tektites from Australia.
These nice pieces are from a small jewelry box of cores, flanges and partial buttons I picked up at an earlier show. I have had them sitting around here for some time mulling over how I should go about “marketing” them. I decided to take some of the very best pieces (many of what I got will end up in my usual $7/g Australite tray at future shows). Here I have two membrane boxes of specimens. The smaller one has the crème de la crème of the batch in it – an almost 1/2 complete slightly tear-drop button with a really large/ clear flange around ½ of it. With it is a partial core that has a nice (but thinner) flange around part of it. In between these two is a nice core that shows some nice pressure waves on the front and three partial flanges place almost perfectly at the points of a triangle. The other batch hs 10 specimens in it. This has a nice assortment of cores with nice partial flanges in the top row, smaller cores that have partial flanges or really strong pressure waves in the center row (4 pieces) and 3 nice flange fragments (as naturally found) in the bottom row. I can’t even remember how long ago it was when I last had specimens like these. I finally managed to locate the location info I had written down on these. That says these are from Charlotte Waters (I assume that is a locality and not just a person’s name), Northern Territory, Australia.
a) 3 specimens in membrane box including ½ teardrop flanged button - $600
b) 10 specimens (flanges/ cores, flanged cores) in membrane box - $500

CANYON DIABLO, Arizona: Coarse octahedrite (IAB). Found 1891.
This is a neat complete slice that Marlin (of Montana Meteorite Lab, excellent meteorite cutting and prepping fame) did as kind of labor of love test. He decided to see just how high a polish he could get on a piece of this material. I don’t remember just how long he said it took him (something like 20 plus hours of actual direct labor seems familiar), just that this would be “unaffordable” if he tried to get his labor value back out of this piece. As expected, this has a pretty much high mirror look to it. One important note: this has NOT been coated. This allows its natural mirror-like quality to really shine, BUT I’d suggest letting me give it a quick spray if you live in a humid environment. I use Deft, which can easily be removed if you decide you don’t want the coating later. A neat slice, with a neat shape and a really nice troilite inclusion at one end.
360.7g mirror polished compete slice – 1700 x 45mm x 6mm - $650
GHADAMIS, Libya: Ordinary chondrite (L6). Fell August 26, 2018.
I know, this is NOT an official name. I think this stuff is (officially) being called “HaH 346”. THAT is listed as “Fall? – No but possible”. The fireball was widely seen in the area and people went out to the likely fall area and started finding beautiful fresh stone meteorites right in the expected area. However, because someone wasn’t actually directly IN the fall area (and saw stones hit the ground or have on pass through a roof/ vehicle or such) it must now be reported as a “possible” fall (this is because of some serious “monkey business” of some people in the past using bright fireballs as a way to sell nice fresh pieces of already known meteorites as “completely new” meteorite fall specimens for some seriously exorbitant prices. Some of these folks got caught at the that game, so now it is MUCH harder to get something reported fully as a fall). I can also tell that these are from a witnessed fall as some of the pieces I have seen recently are already showing signs of rusting. The two pieces I have here are ones that were recovered fairly early after the fall. The crust on both is quite fresh but the smaller of the two does have adhering dust/ dirt that makes the crust look a bit lighter colored in places and the larger piece has a couple tiny areas on one end that show some minor (very minor) orange coloration. Regardless, these piece are far nicer/ fresher than some of the pieces of this meteorite I have been offered lately. Also, these are priced at the same price that was being asked (wholesale!) on those weathered pieces.
a) 236.2 gram complete individual – 80mm x 50mm x 40mm - $295
b) 316.0 gram complete individual – 70mm x 55mm x 50mm - $395

MURCHISON, Australia: Carbonaceous chondrite (CM2). Fell September 28, 1969.
Here is a piece that I could have sold in Tucson if I had it labeled right. This was dropped off with me while I was still moving into/ setting up my room for the show. It came with a “Dave Mouat Collection” card that said it was 11.1 grams “with partial fusion crust”. Yep, this does have a nice long edge of obvious fusion crust (along about 1/3 of its exterior edge). I failed to notice that this card said “fragment”. Well, this IS certainly Murchison but it is a really nice thin slice and, even better, it is actually a COMPLETE slice. The other 2/3 of its edge, on more careful inspection shows are also fusion crusted, all be it with thinner/ secondary crust. The reason I said this would have sold if I had it labeled right at the show is that very few people were looking to spend $7000on a piece of Murchison (which is what this was priced at at the start). However, I had a couple people interested in a piece about one third to one half that size. Well, it was sitting right there, I just didn’t know it until I took the thing out of its holder and decided to actually weigh it. Oh well, now someone out there seeing this list will have a shot at a really nice complete slice of Murchison.
3.86 gram complete slice – 38mm x 30mm x 1mm - $2450.
NWA (6370): Stony-Iron (Mesosiderite). Found 2010. Tkw = 386 grams.
Here are some nice complete slices of a beautiful mesosiderite that I have actually had (but didn’t know it) for quite a long time. These were in a sandwich bag tucked under other things that I did know about and had been offering for quite some time. It was “digging deeper” for more of some of that material that brought these to the surface. Part of the reason that these remained hidden is that I had so little of the material to begin with. But then, how much could I have if the starting mass was under 400 grams (subtract off the research piece(s), a nice piece or two the original owner likely kept, maybe a couple more he may have sold and there is Not much remaining (plus I sold a couple of these in Tucson). Overall, mesosiderites are quite under appreciated. In the collecting world, they are far, far rarer (in number of different and weights available) then the (admittedly) much prettier pallasites. Also, many of the mesosiderites (I am looking at you Vaca) are often quite weathered. These pieces are really nice, fresh, complete slices. They are absolutely loaded with metal and have the occasional large silicate inclusion – classic mesosiderite look to them. About the only “negative (?) on these is that they have not been polished (could do this but fear that may “pluck” out a fair number of the larger silicate inclusions). However, as these were obviously cut with a wire-saw, you have to look really carefully to notice this “problem”.
a) 16.6 gram complete slice – 60mm x 40mm x 2mm - $350
b) 23.1 gram complete slice – 55mm x 46mm x 2mm - $470
NWA (10023). Stony-iron. Pallasite (Main group, anomalous). Found 2014. Tkw 6.95kg.
Apparently, one mass was found near the Moroccan/ Algerian border. Research work on this showed that it seems to be related to the main group pallasites but that the metal in this particular pallasite is unusually high in plessite (this is a fine-grained, high nickel content mix of Kanacite and taenite (the first being the usual low in nickel Fe/Ni alloy – making up hexahedrites in their entirety and Taeninte being the high nickel alloy in iron meteorites – making up the enrirety of nickel-rich ataxites). For those of you that have been collectiong awhile, the most obvious example of an entire meteorite basically being plessite is the famous NWA 859 meteorite – better known as Taza. This is a nice complete slice of this unusual pallasite (obviously cut from near one of the ends – either that or another piece of this was found since the Met Bull publication of it). This does show some transmittance of light through a couple of the crystals, but it is low (and dark) enough that I have not bothered to try to take photos showing this (plus we seem to be stuck under endless gray skies. I installed a new solar hot-air panel on my house the day before Christmass and I swear we have not had more than a few (single digit number while I have been home) since!).
6.86 gram complete slice – 35mm x 25mm x 1mm - $675
Shipping: Shipping rates, right now, have gone up yet again. They seem to have added a "holiday time surcharge". Now it seems that the cheapest I can send a small padded envelope order for is close to $6 at the moment. Regardless, I'll keep the shipping on these (they are small and light weight) at a simple $5 for now for US shipping.
Small overseas orders are around $16 (Canada seems to be right around $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. However, for overseas orders, it probably is best to go ahead and use my brmeteorites@yahoo.com e-mail when possible.
