Mineral resources are any component of the subsoil – in the form of solid, liquid, or gaseous matter – that could be extracted for industrial use, including not only minerals but also ores, oil, and natural gas. Reserves of mineral resources are concentrated in the Earth's subsoil (Federal Law 1992; Kotov 2002).

The mineral composition of igneous rocks plays a significant role in determining the rock's properties, appearance, and classification. Here are some common minerals found in igneous rocks: 1. Quartz: Quartz is a common mineral in igneous rocks, particularly in felsic rocks like granite and rhyolite. It's composed of silicon and oxygen and ...
Understanding the chemical and structural classification of minerals requires knowledge of bonding and crystal structure in inorganic solids, particularly solids in which oxygen is an anion.
