Macroscopic Description: Tim McCoy
This small, equidimensional meteorite, measuring ~6 mm on a side, exhibits a uniform, rusty external appearance.

Thin Section (,1) Description: Tim McCoy

LAP 03916 - Reflected Light
Reflected Light
An end cut of this meteorite with a surface area of ~5 by 6 mm was mounted as a polished thin section and examined. The meteorite consists entirely of kamacite with an average Ni concentration of ~6 wt. %. The only structure revealed by nital etching is several sets of Neumann bands. Many of these bands are subsequently distorted and heat alteration is prevalent at the edges of the section, although weathering appears to have removed any fusion crust. The meteorite is classified as an ungrouped iron, but its small size suggests that it is probably not representative of the larger mass from which it was derived.
