What type of rock is the granite?
In the field observation, sedimentary rocks often have a layered structure, layered structure is a unique feature of sedimentary rocks. In the area where the magmatic rocks develop, the joints are often seen, and basically do not see the bedding. In the mineral assemblage, minerals such as olivine, pyroxene, amphibole and other minerals present in magmatic rocks are at high temperatures Under high pressure conditions, the formation of crystals, under normal temperature and pressure conditions is not easy to save, therefore, in the magmatic rocks appear in the sedimentary rocks rarely seen. Even the same family of minerals, such as although there are feldspar, they are not the same in the composition. Feldspar in sedimentary rocks are generally potassium feldspar and sodium-rich acid plagioclase, and often in the magmatic rocks to see the relatively high calcium content and neutral plagioclase, which are not seen in the sedimentary rocks The
Magmatic rocks are also called igneous rocks, magma formed in the depths of the crust or in the upper mantle, formed in the upper part of the crust or ejected to the surface to cool and consolidate and crystallize. Because the conditions it generates are very different from sedimentary rocks, its characteristics are also significantly different from sedimentary rocks.
Granite is a magmatic rock.
Granite (Granite), the main component of the continental crust, is a kind of magma formed in the surface below the formation of igneous rocks, the main components are feldspar, mica and quartz. The granite language is the Latin granum, meaning grain or grain. Because granite is a deep diagenetic, often able to form a well-developed, visually discernible mineral particles, hence the name. Magmatic rock, also known as igneous rock, is formed by the magma sprayed on the surface or into the crust cooling and solidification of the formation of the rock, there are obvious mineral crystal particles or pores, accounting for about 65% of the total crust. Magma is hot and viscous in the depths of the crust or from the upper mantle, containing volatile silicate melts. Is the formation of a variety of magmatic rocks and magma deposits of the mother. The whole process of magmatic occurrence, migration, aggregation, alteration and condensing diagenesis is called magma.
