Calcite and dolomite are the major rockforming minerals in carbonatites. Other carbonates include the Ferich varieties and some of the much rarer REE (rareearth element) carbonates. Table 3 lists some of the minerals commonly found in carbonatites. The division of most carbonatites into three groups is based on whether calcite, dolomite, or Ferich carbonates (see MINERALS | Carbonates) are ...

· calcite calcite Origin and occurrence: A large percentage of the calcite in rocks was deposited in sedimentary environments; consequently, calcite is a constituent of several diverse sediments, sedimentary rocks, and their metamorphosed products. A minor amount of the Earth's calcite is of magmatic (, igneous) origin; it is the chief constituent of the rare rock called carbonatite.
· Calcite has a distinct level of hardness and in most cases, it can be distinguished from similar materials through simple scratch testing. Quartz and gypsum are often confused with calcite, but since calcite is much softer than quartz and considerably harder than gypsum, these materials can be easily identified from one another. Other similar minerals, such as aragonite and dolomite, can be ...
