Definition

Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase

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

Formation

Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.

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.
