What Is The Sedimentary Rock Of Granite

It forms from the slow crystallization of magma below earth s surface.

What is the sedimentary rock of granite. Granite belongs to the intrusive category of igneous rock which means it formed below the earth s surface as magma slowly cooled and crystallized. Outcrops of granite tend to form tors domes or bornhardts and rounded massifs. Gneiss is a metamorphic rock granite is an igneous rock and sandstone is a sedimentary rock. It is the most abundant basement rock that underlies the relatively thin sedimentary veneer of the continents.

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of small particles and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the earth s surface. It erodes into sediment and then gets compressed into a sedimentary rock. Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals this mineral composition usually gives granite a red pink gray or white color with dark mineral. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye.

Granite containing rock is widely distributed throughout the continental crust. The mineral constituents that create these rocks get recycled over time. Sedimentary rocks can be organized into two categories. The first is detrital rock which comes from the erosion and accumulation of rock fragments sediment or other materials categorized in total as detritus or debris.

Sedimentary rock rock formed at or near the earth s surface by the accumulation and lithification of sediment or by the precipitation from solution at normal surface temperatures. These rocks primarily consist of quartz feldspar and mica. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment.

Sedimentary rocks are the most common rocks exposed on the earth s surface but are only a minor constituent of the entire crust. All rocks undergo a series of processes called the rock cycle where one type of rock changes into another. The sedimentary rock becomes metamorphic with heat and pressure. Much of it was intruded during the precambrian age.

Granite river rocks can have a speckled or banded appearance due to the coarse grains of minerals usually quartz and feldspar that form the granite composite. Its three main minerals are feldspar quartz and mica which occur as silvery muscovite or dark biotite or both.
