What Are the Differences Between the Minerals Calcite and ...

Quartz and calcite are common minerals in the rocks around the world. Both minerals form in a variety of colors, such as purple, white, brown, gray and colorless, which at times makes them appear similar.

difference between quartz calcite and dolomite

Calcite mainly contains calcium carbonate and quartz mainly contains silicon dioxide. The hardness of quartz is higher than that of calcite. Quartz has Mohs hardness of 7, whereas calcite has Mohs hardness of 3. Therefore, calcite can be scratched by fingernail.
