Macroscopic Description - Carol Schwarz | |
The fusion crust on this pallasite is polished and weathered and covers eighty percent of the exterior surface. The specimen has an irregular shape and some yellow crystals are visible on the exterior. The interior consists of metal with some clear white and yellow minerals. A minor amount of evaporite deposit is present. | |
Thin Section Description (,2) - Brian Mason | |
The section consists almost entirely of nickel-iron, with a few anhedral grains of olivine, up to 0.6 mm across, at one margin. The section is rimmed with brown limonite, evidently the product of weathering. Olivine composition is Fa12. The specimen appears to be a fragment of a pallasite. |
