Mineralogy applies principles of chemistry, geology, physics and materials science to the study of minerals. Mineralogy [n 1] is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts.
The halide minerals are compounds in which a halogen (fluorine, chlorine, iodine, or bromine) is the main anion. These minerals tend to be soft, weak, brittle, and water-soluble. Common examples of halides include halite (NaCl, table salt), sylvite (KCl), and fluorite (CaF 2).
The resource curse, also known as the paradox of plenty or the poverty paradox, is the hypothesis that countries with an abundance of natural resources (such as fossil fuels and certain minerals) have lower economic growth, lower rates of democracy, or poorer development outcomes than countries with fewer natural resources.

Ferromagnesian minerals are the principal hosts for nickel, cobalt, copper and zinc in sulfide-poor mafic and ultramafic rocks, and are retained higher in the profile than sulfide-hosted metals. [1] They are leached from the upper horizons and reprecipitate with secondary iron-manganese oxides in the mid- to lower saprolite.
