>>>>>>>>>>>>>>>>>>>>>>>>>>
Touat 008 27.150°N , 01.042°W
Adrar, Algeria
Find: 2023 Feb
Classification: Lunar (troct. melt breccia)
History: Found in Algeria in February 2023 and purchased from the finder by Mbark Arjdal in Febriary and May 2023.
Petrography: (A. Irving, UWS, and P. Carpenter, WUSL) Breccia dominated by mineral debris and some lithic clasts related to troctolitic lithologies. Mean grainsize is ~100 µm. Portions of the very fine grained matrix exhibit fluidal textures and contain sparse vesicles. Accessory phases include Cr-bearing pleonaste, troilite (commonly altered to secondary barite), low-Ti chromite and calcite (as patchy secondary alteration of plagioclase).
Geochemistry: Anorthite (An95.9-96.8Or0.1-0.0, N = 4), olivine (Fa20.0-24.0, FeO/MnO = 74-89, N = 5), pigeonite (Fs19.4-19.9Wo5.0-6.9, FeO/MnO = 42-55, N = 4), subcalcic augite (Fs13.0Wo34.4, FeO/MnO = 40; Fs27.5Wo21.7, FeO/MnO = 51; Fs43.9Wo29.2, FeO/MnO = 63; N = 3).
Classification: Lunar (troctolitiic melt breccia). This material is similar in many respects to Rafsa 002.
