Carbonates are also found in some types of igneous rock such as carbonatites and in relatively low temperature hydrothermal and mineralizing environments. The carbonates have several important uses—Ca carbonates in the manufacture of cement, dolomite in refractory materials, and siderite and rhodochrosite as sources of iron and manganese.
