Metbase description: Show/Hide
A brownish gray stone of 174g covered by fusion crust was found in the Dhofar region of Oman; classification and description (A.Greshake, Berlin): a feldspathic fragmental breccia consisting of clasts of various lithologies embedded into a devitrified fine-grained matrix; schlieren and vesicles are abundant; feldspar, An96.5-99.5; pyroxene, Fs21.9-46.2Wo3.0-41.4; olivine, Fa29.3-47.8; augites are more abundant than Ca-poor pyroxenes and often contain pigeonite exsolution lamellae; accessory phases are Fe-Ni metal, ilmenite, and Ti-Cr-rich spinel; crystalline fragments include large gabbroic anorthosites, high-Al highland basalts, microporphyritic impact melt breccias, dark fine-grained impact melt breccias, and large cataclastic feldspar; no regolith components, e.g., glass spherules, have been identified; low bulk concentrations of MgO and FeO reflect low abundance of mafic components, J.N.Grossman and J.Zipfel, Met.
