What is the mineral composition of most rocks? About 200 minerals make up the bulk of most rocks. The feldspar mineral family is the most abundant. Quartz calcite and clay minerals are also common. Some minerals are more common in igneous rock (formed under extreme heat and pressure) such as olivine feldspars pyroxenes and micas.
