This article describes the microstructures of the various meteorite types, lists the minerals typically found in them, explains color etching techniques, and describes the metallography of the Odessa and Coahuila meteorites.
Meteorites are grouped into three basic types: stones, stony irons, and irons. Within these groups, the classification of meteorites is a complex subject.
For the iron meteorites, classification is based upon chemical composition, macrostructure, and microstructure. Basically, iron meteorites fall into
three categories – hexahedrites, octahedrites and ataxites. However, some do not fully fit the requirements of these categories and are classified as
