Talc is found as a metamorphic mineral in veins, in foliated masses, and in certain rocks. It is often associated with serpentine, tremolite, forsterite, and almost always with carbonates (calcite, dolomite, or magnesite) in the lower metamorphic facies.It also occurs as an alteration product, as from tremolite or forsterite. One of the remarkable features of talc …
