Plessite

Uncategorized

Plessite is a meteorite texture consisting of a fine-grained mixture of the minerals kamacite found in the octahedrite. It occurs in gaps (its name is derived from the Greek "plythos" meaning "filling" ) 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 * acicular or type I plessite * black or type II plessite * cellular or type III plessite * comb plessite * net plessite * pearlitic plessite * spheroidized plessite
