Brenham Pallasite Meteorite part slice 100gram peridot olivine nickel iron

Description

For auction: Brenham pallasite part slice approximate dimensions 100gm x 8cm x 5cm x 0.4cm thick, found and cut by me (Don I Stimpson, Ph.D. aka "don pallasite"). Not polished, coated with an acrylic polymer which can be removed with acetone. No price gouging, no shill bidding.
Our museum is closed, an archived page here: http://www.kansastravel.org/kansasmeteoritemuseum.htm
For storage I recommend an air tight container (desiccator) with molecular sieve 4A. You can also purge the air in the container with argon to remove oxygen. S
mall bottles of argon are sold to preserve opened wine. Earth's atmosphere contains about 21% oxygen which can oxidize meteorite green peridot to orange/red color & fracture. Or, my favorite, pull hard vacuum in the desiccator and put the slice "back in space".
Btw, we sold most of our material when the museum closed but still have several hundred pounds of Brenham meteorite.

Stony-iron. Pallasite (PAL).
About twenty masses were found, weighing together about 2000lb individual
masses weighing from 1oz to 466lb. Described, with an analysis of metal,
10.35 %Ni, G.F. Kunz, Am. J. Sci., 1890, 40, p.312. Many other small masses,
weighing mostly less than 450g were found in 1892, R. Hay, Am. J. Sci.,
1892, 43, p.80. Partially to completely oxidised fragments and limonitic
masses ("meteorodes") were found in a swampy depression which is probably a
meteorite crater, Haviland Crater, associated with this fall, H.H. Nininger,
Trans. Kansas Acad. Sci., 1929, 32, p.63, H.H. Nininger, Am. Miner., 1938,
23, p.536 (M.A. 7-177). A mass of 740lb was found in 1947, 0.75 miles WNW. of
the crater, also others of 474lb., 381lb., 357lb., 220lb., and 110lb at
depths of between one and two feet, and more recently, at a depth of 5ft
3in, a mass of 1000lb. This has been described, incorrectly, as the world's
largest pallasite, (compare, for example Huckitta, 2 tons). Metallography,
