Sample No.: ALH85006 Location: Allan Hills Weight (g): 49.0 Field No.: 2660 Dimensions (cm): 4 x 3 x 3 Meteorite Type: C3V Chondrite
Macroscopic Description: René Martinez Fusion crust is present on only one surface of this coherent stone. The interior is made up of chondrules, up to 2 mm in diameter, and irregular white inclusions, up to 3 mm in longest dimension.
Thin Section (,5) Description: Brian Mason The section shows a variety of chondrules (up to 2.5 mm across), chondrule fragments, and irregular clasts in a dark brown to black matrix. Fine-grained opaques are dispersed throughout the matrix and rim some of the chondrules. The matrix consists largely of fine-grained iron-rich (Fa45-47) olivine. Olivine in the chondrules and mineral fragments is usually near MgSiO4 in composition, but more iron-rich grains are also present. Pyroxene is much less abundant than olivine, and is close to MgSiO3 in composition. The meteorite is a C3 chondrite of the Vigarano subtype. | ||||||||||||||||||||
