Name: Dominion Range 10660 This is an OFFICIAL meteorite name. Abbreviation: DOM 10660 Observed fall: No Year found: 2010 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 23.5 g
Macroscopic Description - Cari Corrigan and Tim McCoy
The main mass of this meteorite is roughly triangular in cross section with an irregular bumpy, brown surface and occasional rust haloes. This description is uniform across the entire surface.
Thin Section Description (,2) - Cari Corrigan and Tim McCoy
A 1.0 x 1.5 cm slice of this meteorite was examined. This section consists of equidimensional kamacite grains up to 2.5 mm wide with interstitial ribbons of taenite and schreibersite. At the edges of the meteorite, kamacite exhibits the α2 structure. Within and crosscutting kamacite grains are swarms (up to 1 mm in size) of equant graphite crystals up to 50 microns in maximum dimension (in one case, associated with sulfide). The shape of the graphite crystals is largely controlled by the structure of the metal. Elongate areas reaching 4 mm in length are also composed of swarms of elongate graphite. The average composition based on a microprobe traverse of 100 points is 8.9 wt% Ni, 0.9 wt% P. The meteorite is anomalous but may be related to graphite-rich IAB irons, e.g. Kendall County.
