What Is Granite In Sedimentary Form

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

What is granite in sedimentary form.

Formally granite is a plutonic rock that is composed of between 10 to 50 quartz typically semi transparent white and 65 to 90 total feldspar typically a pinkish or white hue. A rock with a similar composition and appearance as granite gneiss can form through long and intense metamorphism of sedimentary paragneiss or igneousrocks orthogneiss. It forms due to crystallization from magma. No granite is an igneous rock.

It is the most abundant basement rock that underlies the relatively thin sedimentary veneer of the continents. Granite is an intrusive igneous rock which means it was formed in place during the cooling of molten rock. Sedimentary rocks are formed on or near the earth s surface in contrast to metamorphic and igneous rocks which are formed deep within the earth. All rocks undergo a series of processes called the rock cycle where one type of rock changes into another.

Sedimentary rocks form as a result of weathering and deposition from previously formed rocks and are usually much softer than igneous or metamorphic rocks. It is an igneous rock. Granite containing rock is widely distributed throughout the continental crust. This mineral composition usually gives granite a red pink gray or white color with dark mineral grains visible throughout the rock.

Outcrops of granite tend to form tors domes or bornhardts and rounded massifs. These rocks primarily consist of quartz feldspar and mica. The mineral constituents that create these rocks get recycled over time. Granite is not a sedimentary rock.

The most important geological processes that lead to the creation of sedimentary rocks are erosion weathering dissolution precipitation and lithification. Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals. The word granite comes from the latin word granum a grain in reference to the coarse grained structure of such a crystalline rock. Gneiss however is distinguished from granite by its strong fabric and alternating dark and light colored bands.
