Mineral Database | National Museum Wales

Introduction: calcite occurs in a great diversity of parageneses and geological settings. It is an important rock-forming mineral (e.g. as the major constituent of limestone); it is a widespread product of low to medium-grade metamorphism and hydrothermal alteration in many rock-types and it is a common hydrothermal vein-mineral.
