Writeup from MB 88:

Northwest Africa 1951

Morocco

Purchased 2003 April and May

Mesosiderite

Several stones totaling 17 kg of the same meteorite were purchased in Talsit in 2003 April and May. Classification and mineralogy (A. Jambon and O. Boudouma, UPVI): breccia consisting of orthopyroxene clasts (> 5 mm) and orthopyroxene-rich matrix with rare plagioclase. No lithic plagioclase or olivine clasts were observed. Metal is bimodal, mm-sized large blebs and small spots in matrix. Orthopyroxene, FeO/MnO = 30.4, En68Fs30Wo2; plagioclase, An89-92; low-Ni metal; troilite, Ca-phosphate, silica. Mineral modes: metal, 25 vol%, troilite, 5 vol%, plagioclase, ~3 vol%, orthopyroxene, 63.3 vol%. A mesosiderite tentatively assigned to class C as NWA 1827.  Pairing of the two was suggested by T. Bunch although NWA 1827 does contain plagioclase clasts. Specimens: type specimen, 35 g, UPVI; main mass, Moroccan Imports Chula Vista Ca.
