Rocks and minerals / Породы и минералы

This guide covers over 320 of the most important rocks and minerals found all over the world. The book begins with a short introduction, which focuses on the process of identifying different rocks and minerals. The following pages divide rocks into three groups: sedimentary, igneous, and metamorphic; and minerals into two groups: ore minerals and rock-forming minerals. Introductions to each of these sections define the groups and explain how entries are organized within them.
