Talc carbonate - Wikipedia
Talc carbonates are a suite of rock and mineral compositions found in metamorphosed ultramafic rocks.. The term refers to the two most common end-member minerals found within ultramafic rocks which have undergone talc-carbonation or carbonation reactions: talc and the carbonate mineral magnesite.. Talc carbonate mineral assemblages are controlled by temperature and pressure of …

Talc Mineral Production - Formation of Talc | Golcha Minerals
Talc is basically a mineral which belongs to the class of silicates. The formation of talc is achieved when the carbonate sediments undergo through contact metamorphosis.It is also formed when the magmatic rocks which are rich in magnesium undergoes the hydrothermal alteration.The rocks which contain talc are metamorphic in nature and therefore talc is produced as secondary mineral.
