Title: Magnetite morphologies in the Essebi and Haripura CM chondrites
Authors: Hyman, M.; Ledger, E. B.; Rowe, M. W.

Many of the unusual magnetite morphologies previously observed only in the CI chondrites have been seen in the CM chondrites, Essebi and Haripura. These include: heavily textured spheroids, which are possibly spherulites, found both singly and in groups of up to a dozen and ranging in size from about 4 to 10 microns in diameter; collections of microcrystals varying from about 0.3 to 6 microns in diameter; spheres of about 1 to 6 microns in diameter; layered, nearly circular plates, forming a spheroidal plaquette about 7.5 microns in diameter; clusters of variable sized nodules, about 1.5 to 6 microns, with concave features; framboidal magnetite; and finally, collections of less distinctive globules.
