Rhyodacite and Talc carbonate

1 Definition
1.1 Definition
Rhyodacite is an extrusive volcanic rock intermediate in composition between dacite and rhyolite
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

5 Formation
5.1 Formation
Rhyodacite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
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.

All about Rhyodacite and Talc carbonate Properties

Know all about Rhyodacite and Talc carbonate properties here. All properties of rocks are important as they define the type of rock and its application. Rhyodacite belongs to Igneous Rocks while Talc carbonate belongs to Metamorphic Rocks.Texture of Rhyodacite is Earthy whereas that of Talc carbonate is Very Soft. Rhyodacite appears Skeletal and Talc carbonate appears Soft. The luster of Rhyodacite is greasy to dull while that of Talc carbonate is pearly. Rhyodacite is available in black to grey, dark greenish - grey colors whereas Talc carbonate is available in colourless, grey, white colors. The commercial uses of Rhyodacite are cemetery markers, creating artwork and that of Talc carbonate are manufacturing of baby powder.
