d) Illite (Fine-grained micas, mica-like minerals) Illite is the most common clay mineral, often composing more than 50 percent of the clay-mineral suite in the deep sea. They are characteristic of weathering in temperate climates or in high altitudes in the tropics, and typically reach the ocean via rivers and wind transport. Illite type clays ...
Silicate Mineral Groups Common Minerals in Crust. Silicate minerals are the most common minerals on Earth, with the continental crust dominated by quartz, feldspar, and muscovite, and the oceanic crust dominated by olivine, pyroxene, and amphibole. All silicate minerals employ the silica tetrahedron as a building block, with covalent bonds.
