Definition

Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar

Formation

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Talc Carbonate is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.
