Definition
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.
Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth

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.
Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

All about Talc carbonate and Basalt Properties
Know all about Talc carbonate and Basalt properties here. All properties of rocks are important as they define the type of rock and its application. Talc carbonate belongs to Metamorphic Rocks while Basalt belongs to Igneous Rocks.Texture of Talc carbonate is Very Soft whereas that of Basalt is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Talc carbonate appears Soft and Basalt appears Dull and Soft. The luster of Talc carbonate is pearly while that of Basalt is not available. Talc carbonate is available in colourless, grey, white colors whereas Basalt is available in black, brown, light to dark grey colors. The commercial uses of Talc carbonate are manufacturing of baby powder and that of Basalt are an oil and gas reservoir, commemorative tablets, creating artwork, used in aquariums.
