Abstract

The Beenham meteorite contains native copper and ilmenite in addition to the common minerals characteristic of the hypersthene chondrites. The metal contains Neumann lamellae, some greatly deformed, as well as areas of apparent flowage. The troilite is a relatively late phase, having replaced kamacite within plessitic intergrowths. Troilite locally displays twin lamellae. Elsewhere it is in braided veinlets and in globules, both reflecting former melting. These varied textures indicate a complex history encompassing several deformational events, presumably due to parent body impacts and perhaps breakups.
