The Ore Minerals Under the Microscope

An Optical Guide


  • Bernhard Pracejus, Department of Geochemistry, Free University Berlin, Germany

This is a very detailed colour atlas for ore/opaque minerals (ore microscopy) with the main emphasis on name and synonyms, mineral group, chemical composition, information about major formation environment, optical data, reflection colour/shade comparison with 4 common/standard minerals of a similar colour or grey shade, up to 5 high-quality photos for each mineral with scale, and a short description of the pictures. A compilation from some of the prominent publications in the field of ore microscopy yielded a list of 431 minerals are included in this atlas.
