Name: Elephant Moraine 16045 This is an OFFICIAL meteorite name. Abbreviation: EET 16045 Observed fall: No Year found: 2016 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 105.1 g
Macroscopic Description - Cari Corrigan, Tim McCoy
This iron meteorite appears to be ~2/3 of an oriented mass with a strongly convex upper surface and strongly concave lower surface. The original meteorite was probably ~5 cm in diameter (but is currently 2 x 3 x 4.5 cm). The broken surface exhibits angular protrusions that appear to approximate angles in the Widmanstätten pattern, and a prominent 3 mm thick fusion crust is evident on margins of the broken surface. This meteorite has a weathering grade of A/B.
Thin Section Description (,3) - Cari Corrigan, Tim McCoy
A section through the center of the mass exhibits a Widmanstätten pattern with kamacite lamellae of width ~1.4 mm. Kamacite exhibits sub-grain boundaries and α2 structure throughout the section. Taenite of ~100 microns in width exhibits compositional zoning. Coarse comb plessite occurs in the section. Fusion crust is present on one edge of the section reaching 1.6 mm and, in places, exhibits a layered structure. A compositional traverse across the section yielded 8.3 wt. % Ni and 0.12 wt. % P. The structure and composition are consistent with a IIIAB iron. View the 3D Rendering.
