3 Minerals – An Introduction to Geology

In geology, the classic definition of a mineral is: 1) naturally occurring, 2) inorganic, 3) solid at room temperature, 4) regular crystal structure, and 5) defined chemical composition.

2.6: Classes of Minerals

SILICATES. Based on the polyatomic anion, (SiO 4) 4–, which has a tetrahedral shape.Most minerals in the earth's crust and mantle are silicate minerals. All silicate minerals are built of silicon-oxygen tetrahedra (SiO 4) 4– in different bonding arrangements which create different crystal lattices. You can understand the properties of a silicate …

4.5: Formation of Minerals

Most of the minerals of Earth's crust formed through the cooling of molten rock (magma or lava). Molten rock is very hot, typically on the order of 1000 (^{circ})C (1800 (^{circ})F) or more. Heat is energy and temperature is a measure of that energy. Heat causes atoms to vibrate and temperature measures the intensity of the vibration.

Optical Properties of Minerals

The optical properties of minerals refer to their behavior in the presence of light and how they interact with light when observed using various optical techniques. These properties include transparency/opacity, color, luster, refractive index (RI), pleochroism, birefringence, dispersion, extinction, and crystallography.
