how is talc formed

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 is also formed when the magmatic rocks which are rich in magnesium undergoes the hydrothermal rocks which contain talc are metamorphic in nature and therefore talc is produced as secondary mineral...
