Name: Dominion Range 19170 This is an OFFICIAL meteorite name. Abbreviation: DOM 19170 Observed fall: No Year found: 2019 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 32.8 g
75% of the exterior has black fusion crust with fractures, pits and some oxidation. Evaporites are present and exposed interior is a dark matrix with some inclusion/chondrules visible. The interior is black fine grained matrix with some brown oxidation. The visible inclusions/chondrules are lighter than matrix and some are weathered. Very similar to 179.
Thin Section Description (,,2) - Cari Corrigan, Tim McCoy
The sections consist of abundant small (up to 1 mm) chondrules, chondrule fragments, CAIs, and mineral grains in a dark matrix. Metal and sulfide occur within and rimming the chondrules. Olivine ranges in composition from Fa0-60. Pyroxene analyses range from Fs0-33. Terrestrial weathering effects are modest. Meteorites are similar enough that one description suffices, and they are likely paired. The meteorites are CO3 chondrites and may be members of the larger Dominion Range CO3 pairing group (named for DOM 08004).
