Qued Mya 005 30.035°N, 3.916°E Ouargla, Algeria Find: 2022 Jan Classification: Martian meteorite (Nakhlite) History: Many small stones found together in Algeria in January 2022 were purchased by Ziyao Wang in February 2022 from a dealer in Laayoune, Morocco. Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Relatively coarse grained assemblage of predominantly olivine (as unzoned anhedral grains up to 4 mm) and augite (as zoned stubby prismatic grains) together with subordinate low-Ca pyroxene (possibly orthopyroxene), titanomagnetite (containing submicron ilmenite exsolution lamellae), intercumulus plagioclase and accessory Cl-F-bearing apatite. Crystallized melt inclusions (up to 100 microns in size) containing Ti-Al-bearing augite, troilite and glass are present in olivine. Very fine-grained "chlorophaeite" material (orange-brown in thin section) is present a thin veinlets in olivine and also in interstitial patches between the other phases. Geochemistry: Augite (cores Fs25.1-26.5Wo40.6-39.9, rims Fs34.8-35.9Wo38.1-37.2, FeO/MnO = 34-35, N = 4), olivine (Fa70.0-73.2, FeO/MnO = 47-51, N = 6), low-Ca pyroxene (Fs54.8-58.5Wo2.3-3.9, FeO/MnO = 30-37, N = 3, plagioclase (An33-4-37.4Or3.2-2.8, N = 2). Classification: Nakhlite. Specimens: 9.4 g including one polished thin section and one polished mount at UWB; remainder with WangZ. | ||||||||||||||||||||||||||||||||||||
