Name: Dominion Range 19117 This is an OFFICIAL meteorite name. Abbreviation: DOM 19117 Observed fall: No Year found: 2019 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 15.9 g
85% of exterior is covered with fusion crust that is slightly shiny on one side but rough and vesicular on the other. The shiny side also has some radial flow lines and a few white spots that might be evaporites. Exterior surfaces are dark red-brown and porous. Fresh interior is very dark grey-black matrix with a crystalline texture and some small (<0.5 mm) white inclusions. Orange rust throughout.
