Writeup from MB 109:
Zinder 003 Niger Find: June 2019 Classification: Eucrite melt breccia History: The meteorite was purchased from a meteorite dealer in Morocco. Physical characteristics: Dark-grayish rock with minor fusion crust. Petrography: The meteorite is a eucrite-melt breccia composed of up to several mm sized basaltic clasts set into dark melt rock matrix, which is fine-grained and vesicular melt-textured. Basaltic clasts often contain lath-shaped calcic plagioclase. The fine-grained melt rock is mostly recrystallized and mineral grains in contact with the melt are partly resorbed; some regions show flow textures. Geochemistry: The rock contains low-Ca and Ca pyroxene. Low-Ca pyroxene is Fs60.2±2.0Wo3.0±1.8 (Fs54.3-62.4Wo1.7-9.1; n=24) and the Ca-pyroxene has Fs27.2±1.9Wo41.6±2.6 (Fs24.9-30.2Wo41.9-43.8; n=7); the mean Fe/Mn ratio of the pyroxenes is 34.6 (n=31). Calcic plagioclase has a composition of An89.7±1.6 (An86.6-92.4, n=23) | ||||||||||||||||||||||||||
