Here is a small assortment of some interesting things I received recently from an old research collection. There are many things in this collection that I have not cataloged fully yet. Regardless, I am already seeing a bunch of names of things (all really small, good for the micro collectors) that I have never seen or had before. The next couple offerings will likely be things pulled from this collection lot as I catalog them (though I may run an "inventory clearance" offering next time. I am currently working on that grueling task. I have not come across a lot of last one or two pieces of an item things yet – the things I'd probably want to get rid of so I don't have to do all the inventory work on them for taxes – but that may change).
ABEE, Canada: (EH4) impact melt breccia. Fell June 9, 1952. Tkw = 107kg.
This is a nice cut fragment that has a nice 12mm x 7mm patch of fusion crust. This had a thin coating of light rust on it so I hand sanded it to show fresh metal and breccia texture on its cut faces (and stunk up the kitchen in the process. One of the interesting features of most enstatite chondrites is that they stink of sulfur really bad when sanded).
1.95 gram cut fragment – 20mm x 7mm x 7mm - $120
ALLENDE, Mexico: (CV3.2). Fell February 8, 1969.
This is a "black inclusion" that was originally set aside to be thin-sectioned (and it may very well have had a layer cut off for this purpose). This, texturally, looks very much like a CM2 meteorite but the color is a bit lighter. I left this in the bottle I got it in which has a label that says " Allende black inclusion, a piece for thin section 1/24/74, 1.122g.
1.12 gram slice – 10mm x 8mm x 4mm - $15
AOUELLOUL GLASS, Mauritania.
A 250 meter diameter crater was discovered with a small amount of highly silicious glass around it. This glass contains iron and nickel, showing its impact origin. It is estimated that the impact occurred about 3.3 million years ago. These are 3 small pieces that have been sawn for research work and are in the plastic tube I received them in.
1.3 grams 3 pieces - $7
ARRIBA, Colorado: (L5), brecciated. Found 1936. Tkw = 31.1kg.
These piece are both "raw cut" unsanded. I left them as I got them. However, the back side of both is really nice in that they have very nice obvious weathered fusion crust (not badly weathered either. The crust is a nice mix of dark gray and chocolate brown). These are really nice little end pieces and likely very rare as such.
2.2 gram end piece – 18mm x 9mm x 6mm - $20
NEW CONCORD, Ohio: (L6) veined. Fell May 1, 1860. Tkw = 226.8kg.
Here is a US historic classic. I have not had any of this in quite awhile. I remember something about a rumor that a horse was supposedly killed in the fall of this meteorite but don't recall where I heard that.
2.3 gram slice – 17mm x 9mm x 4mm - $45
3.4 gram slice – 22mm x 9mm x 5mm - $65
5.0 gram slice – 40mm x 9mm x 4mm - $95
ORGUIEL, France: (CI1). Fell May 14, 1864. Tkw = 10.5+kg.
I sold a fair amount of this material when I offered it on a list recently. This piece is special in that it is still in the little plastic disk container that a researcher received decades ago (likely directly from the Paris Museum). I have priced this pretty much at the same price per gram (possibly even a hair less) that I had my "regular" material listed at.
.37grams of crumbs in Paris museum container - $700
PANTAR, Philippines: (H5). Fell June 16, 1938. Tkw = 10.3kg (?)
I put a question mark on the total known. This 10.3kg is what Meteorites A to Z reports but I could only come up with about 1600 grams in museum collections (according to the Catalog of Meteorites). Even the Meteoritical Bulletin has the total on this as 2.1kg. It was reported that 16 fairly small stones were recovered from this fall. However, a note was made that "thousands the size of corn and rice grains fell on roofs in the area". Perhaps a big load of these were recently recovered, but I certainly have not ever seen any of this fall available before.
.02 grams fragments/ crumbs in capsule - $15
.03 grams fragments in a capsule - $25
.11g fragment – 7mm x 5mm x 2mm - $80
WALTERS, Oklahoma: (L6). Fell July 28, 1946. Tkw = 28kg.
This is a meteorite that looks like there are only a couple kilos that has made it out of research collections, according to the numbers in the Catalog of Meteorites. These aren't much, but maybe all that is available of this fall at this point in time.
.20 gram fragments in capsule - $20
.7 gram cut fragment – 15mm x 5mm x 3mm - $50
