Everything about the granite

Granite rock Blutuna composed primarily of quartz, feldspar and mica usually also. Is the most abundant rock in the continental crust. Granite freeze happens slowly and very high pressure, with high silica content of magma from the merger in the rocks which form the continents, and under the mantle temperature at the bottom of this.

As this sediment contains less magnesium than of continental crust has the lowest specific weight, and thus rising through the crust in the distinctive structures inverted drop Khaybar, before reaching the surface. And to form granite necessary to consolidate slowly under high pressure. Feldspar size is an indicator of the rate of multiple sclerosis, and if a large feldspar lower rate. These structures appear on the surface due to erosion and called Batholat. Due to the high hardness, it is often at the top of the mountains, which has its own form close to typical.
