Brahin Pallasite

 
This is not the typical way Brahin is viewed.  I was just messing around and thought these shots looked cool. The magnification is approximately 640X, viewed in incident cross polarized light.

Name : Brahin
Location : Gomel region
Co-ordinates : 52?30'N, 30?20'E (approx)
Date of find : 1810
Weight : 823kg approx
Number of pieces : 11

Two masses of about 80kg and 20kg respectively were found in 1810, Ann. Phys., 1819, 63, p.32, and a third of 183kg later, P.I.Grishchinsky, Ann. Geol. Min. Russ., 1911, 13, p.72, M.H.Hey, Cat. Met., 1966, p.67. Analysis of metal, 8.38% Ni, L.L.Ivanov, Ann. Geol. Min. Russ., 1911, 13, p.111. Cooling rate and olivine composition, Fa11.7, P.R.Buseck and J.I.Goldstein, Bull. Geol. Soc. Amer., 1969, 80, p.2141. Areal analysis gave olivine 37.18% by weight, P.N.Chirvinsky, Izvest. Don Polytech. Inst. Novocherkassk, 1929, 11, p.194 (M.A.4-260). There has been considerable confusion over the number and weights of the known masses of this fall. Eight masses reported, totalling 633kg, E.L.Krinov, Katalog Meteoritov Akad. Nauk SSSR, Moskva, 1947, (M.A.10-511). A number of masses are reported, since discredited by Krinov [loc. cit.], P.I.Grishchinsky, Mem. Soc. Nat. Kiev, 1928, 27, (3), p.8 (M.A.4-420). Eleven masses listed, total weight 823kg, including masses of 73kg found in 1952, 12.7kg found in 1968 and 21.8kg found in 1979, G.I.Emel'yanov, Meteoritika
