Talc is formed by the alteration of magnesium rich rocks and many times is found as heavily metamorphosed schists. Talc is an alumino-silicate that is actually a form of Mica.

talc has a white streak
the way a surface reflects light is called talc luster
Talc is classified as a silicate mineral.

Talc is found in India
Talc is formed by the hydrothermal alteration of ultrabasic rocks, or low grade thermal metamorphism of siliceous dolomites.
Talc is a rare form of crystal. Talc is formed from serpentine, amphibole, and olivine. The metamorphism of these minerals with water and carbon dioxide form the rare talc crystal.
One of the softest rocks is Talc. Talc is a mineral not a rock!Minerals are pure, rocks can be formed from one or more minerals. A piece of talc is a rock formed of a single mineral.Clays, are rocks and can be very soft.
