Carbonates, Evaporites, and Accessory Minerals

Accessory Minerals Accessory minerals are those minerals that occur in small quantities in soils. They are generally inherited from the parent materials, and many of them are very resistant to weathering (i.e., they are relatively inert from a chemical perspective).

In rocks, some mineral species and groups are much more abundant than others; these are termed the rock forming minerals. The major examples of these are quartz, the feldspars, the micas, the amphiboles, the pyroxenes, the olivines, and calcite; except for the last one, all of these minerals are silicates.
