This module, the second in a series on minerals, describes the physical properties that are commonly used to identify minerals. These include color, crystal form, hardness, density, luster, and cleavage.
On the basis of their origin, minerals may be divided into primary and secondary minerals. Minerals formed during solidi  cation of magma or lava are called primary minerals, and minerals formed by alteration of the primary minerals and by resyn-thesis and recrystallization during weathering are secondary miner als.
