Mesosiderite

History: A complete stone was purchased in Erfoud by a Moroccan dealer for M. Chinellato.

Physical characteristics: The sample is a single stone of 147 g, partially covered with black fusion crust.
Petrography: (V. Moggi Cecchi and G. Pratesi, MSP) Fine-grained (<0.5 mm) matrix consisting of a relatively homogeneous assemblage of orthopyroxene (42%), plagioclase (18%), metal (20%), troilite (15%), chromite (5%), and accessory merrillite set in a unbrecciated texture. Metal grains are formed by taenite-kamacite aggregates.
Mineral compositions and geochemistry: Orthopyroxene is pigeonitic (Fs_30.1En_66.8Wo_3.1; FeO/MnO = 26.2–29.8). Plagioclase is anorthitic (An_92.1). Oxygen isotopes: (I. Franchi and R. Greenwood, OU) δ¹⁷O = 2.13, δ ¹⁸O = 4.55, Δ¹⁷O = −0.26 (all ‰).

Classification: Mesosiderite (B class); minimal shock, minimal weathering.

Type specimen: A total of 21.3 g of sample and one thin section are on deposit at MSP. MChin holds the main mass.
