Definition
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing 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 Boninite and Talc carbonate Properties
Know all about Boninite and Talc carbonate properties here. All properties of rocks are important as they define the type of rock and its application. Boninite belongs to Igneous Rocks while Talc carbonate belongs to Metamorphic Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Talc carbonate is Very Soft. Boninite appears Dull and Soft and Talc carbonate appears Soft. The luster of Boninite is vitreous while that of Talc carbonate is pearly. Boninite is available in bluish - grey, brown, colourless, green, grey colors whereas Talc carbonate is available in colourless, grey, white colors. The commercial uses of Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo) and that of Talc carbonate are manufacturing of baby powder.
