Common crystals found in coal mines include pyrite, calcite, dolomite, and quartz. These crystals are often formed through the mineralization process in the coal seams and surrounding rocks. Pyrite, in particular, is a common mineral found in coal that can form cubic crystals.
Orthoclase feldspar is commonly found in association with large muscovite crystals. This mineral combination is often seen in pegmatite deposits, where slow cooling allows for the growth of large crystals.
