Abstract. Three minerals contribute to the built-up of Earth’s crust by almost ¾ and predominate in the group of industrial minerals. Feldspar is the top scorer with 56 vol.%; quartz is second most in abundance and accounts for 12 vol.% while phyllosilicates of the mica group are fifth among the top 10 with 4 vol.%.

9 Ore Deposits and Economic Minerals – Mineralogy

Many different mineral commodities are important to modern society. However, when mineralogists think about mining, they are generally thinking of ore minerals that are the sources of important metals, or of minerals that have specific, highly valued properties (e.g., asbestos, micas, potash, and gems of all sorts).That is what we will focus on in most of the rest of this chapter.

Hemley studied the stability of minerals common in hydrothermal systems, including K-feldspar, white mica, pyrophyllite, and kaolin-group minerals (kaolinite and dickite plus nacrite and halloysite). He recognized that the most important controls on the stability fields of these minerals are the activity ratio of K + /H + and temperature ( Fig ...
