Name: Dominion Range 18292 This is an OFFICIAL meteorite name. Abbreviation: DOM 18292 Observed fall: No Year found: 2018 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 10.7 g
Exterior has patches of dark brown-gray fusion crust that is shiny in some areas and rough in others and has flow lines. Exposed interior is light gray with black and white flecks <0.25 mm. Fresh interior is similar to the exposed areas but the flecks are shades of gray rather than black and white.
Thin Section Description (,2) - Cari Corrigan, Tim McCoy
These two brecciated sections consist of fine to medium grained ophitic basalts with apparent shock darkening as veins and patches. Modest iron oxide staining exists in both sections. One 6 mm (max dimension) clast in DOM 18291 exhibits a fine grained, granular texture. Pyroxenes are Fs26-60Wo2-44 and feldspars are An82-86Or1. These two meteorites are similar enough to consider pairing and are eucrites.
