Name: Dominion Range 14170 This is an OFFICIAL meteorite name. Abbreviation: DOM 14170 Observed fall: No Year found: 2014 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 225 g
This ovoid specimen measures ~6 by 4 by 2.5 cm. One half of the specimen is convex and relatively smooth, with numerous indentations of 1-2 mm in diameter. A distinct rim separates the upper and lower surfaces of the meteorite, likely a reflection of oriented flight with melted material streaming to the midpoint. The center ridge is 1-1.5 cm in width and contains regularly-spaced indentations ~7 mm in diameter. We have not observed similar indentations on other iron meteorites. The lower surface resembles the upper surface, but is overlain by the rim material around its edges.
Thin Section Description
(,2)
- Cari Corrigan, Tim McCoy
A complete longitudinal section was studied. The section consists of spare, thin (50-150 micron) kamacite lamellae in a matrix of abundant plessite. Schreibersites occur within the kamacite lamellae. No fusion crust or a2 region was observed. A microprobe traverse across the section yielded an approximate composition of 10.2 wt.% Ni and 0.40 wt.% P. In the absence of additional studies, the relatively high-Ni combined with high-P suggests that this iron may be ungrouped.
