This reference set offers illustrated essentials to study mineralogy, applied to petrology. While there are some excellent reference works available on this subject, this work is unique for its data richness and its visual character.
This compact set will serve as a field manual to students, researchers and professionals in geology, geological, mining, and mineral resources engineering to observe and determine minerals in their studies or field work. Table of Contents
