Detailed explanation-1: -Familiarity with these few minerals – olivine, garnet, pyroxene, hornblende, muscovite, biotite, K-feldspar, plagioclase, and quartz – prepares you to identify and interpret the vast majority of rocks you will see on Earth’s surface.
Detailed explanation-2: -Of the approximately 600 known silicate minerals, only a few dozen-a group that includes the feldspars, amphiboles, pyroxenes, micas, olivines, feldspathoids, and zeolites-are significant in rock formation.
Detailed explanation-3: -Roughly 90 percent of Earth’s crust is made up of silicate minerals.
Detailed explanation-4: -Ortho silicates (or Nesosilicates) Pyro silicate (or Sorosilicates) Cyclic silicates (or Ring silicates) Chain silicates (or pyroxenes) Double chain silicate (or amphiboles) Sheet or phyllosilicates. Three dimensional (or tecto) silicates.
