Metallography of Iron Meteorites

The presentation will describe the microstructures of various meteorite types, list the minerals typically found in them, explain color etching techniques, and describe the metallography of iron=based meteorites such as 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. This presentation will describe the microstructures, list the minerals typically found in them, explain color etching techniques, and describe the metallography.
