Plessite is a meteorite texture consisting of a fine-grained mixture of the minerals
kamacite and
taenite found in the
octahedriteiron meteorites. It occurs in gaps (its name is derived from the Greek "plythos" meaning "filling"[1]) between the larger bands of kamacite and taenite which form
Widmanstätten patterns.
Many types of plessite exist and vary in formation mechanism and morphology. Some types of plessite as named by Buchwald's "Iron Meteorites" and Massalski's "Speculations about Plessite" are:[citation needed]
