The Main Components Of Granite

Granite is a deep acidic igneous rock formed by magma condensation deep underground, and some granites are gneiss or mixed petrified rocks formed by metamorphic magma and sedimentary rocks. The main minerals of granite are feldspar, quartz, black and white mica, etc. The content of quartz is 10% to 50%. The content of feldspar is about 2/3 of the total, and it is divided into orthoclase, plagioclase (soda lime) and microplagioclase (potash). The mineral composition of different species is different, and there may be pyroxene and hornblende.
