摘要:
Inman (find, 1966) is a single, relatively unweathered stone of 7.25 kg that contains fresh metal and only few weathering products away from fractures. It has a pronounced chondritic texture, with 38 vol % of the meteorite being made up of chondrules of virtually all textural types. The recalculated bulk analysis, particularly the ratios of Fetotal/SiO2(0.46), Fe°/Fetotal(0.35), and Fe°/Ni° (6.67) and the contents of Fetotal(19.45%) and metallic nickel‐iron (7.94%), indicate that Inman is an L‐group chondrite. The pronounced chondritic texture; the compositional variabilities of olivine, pyroxene, chromite, and ilmenite; the presence of a fine‐grained, nearly opaque matrix, glass and twinned monoclinic low‐Ca pyroxene indicate that the chondrite belongs to petrolo
