What is the simplest form of minerals?

The simplest form of minerals is often referred to as a "mineral species," which is defined by its specific chemical composition and crystalline structure. Minerals are naturally occurring inorganic substances, and their simplest form typically consists of a single chemical compound, such as quartz (SiO2) or halite (NaCl). These compounds can exist in various forms or varieties, but they retain their fundamental chemical and structural characteristics.
