Is Granite A Clastic Sedimentary Rock

The granite melts into lava then cools becoming igneous.

Is granite a clastic sedimentary rock.

6 1 clastic sedimentary rocks a clast is a fragment of rock or mineral ranging in size from less than a micron 1 too small to see to as big as an apartment block. If a sedimentary rock consists of the shells of organisms is it clastic biochemical organic or chemical. Conglomerate is a clastic sedimentary rock formed from pre existing. A clast is a fragment of geological detritus chunks and smaller grains of rock broken off other rocks by physical weathering.

In general the greater the distance traveled the smaller and more rounded the sediment particles will be. The formation of clastic and organic rocks begins with the weathering or breaking down. The sedimentary rock becomes metamorphic with heat and pressure. Sedimentary rocks form as a result of weathering and deposition from previously formed rocks and are usually much softer than igneous or metamorphic rocks.

Organic sedimentary rocks like coal form from hard biological materials like plants shells and bones that are compressed into rock. Breccia is a term most often used for clastic sedimentary rocks that are composed of large angular fragments over two millimeters in diameter. Deep marine deposits are wedge shaped deposits consisting of coarse sediments and a large amount of feldspar typically at the foot of an eroding mountain range whereas deposits consist mostly of. Geologists use the term clastic with reference to sedimentary rocks as well as to particles in sediment transport whether in suspension or as bed load and in sediment deposits.

Clastic rocks are composed of fragments or clasts of pre existing minerals and rock. Clastic sedimentary rocks are subdivided according to the dominant particle size. One easy way to. Clastic rocks are composed largely of quartz feldspar rock lithic fragments clay minerals and mica.

It forms due to crystallization from magma. Any type of mineral may be present but they in general represent the minerals that exist locally. Granite is an intrusive igneous rock formed from the cooling and solidifying of felsic magma at depth within the earth s crust. Various types of clasts are shown in figure 5 12 and in exercise 5 3.

Clastic sedimentary rocks are composed of other rock fragments that were cemented by silicate minerals. It erodes into sediment and then gets compressed into a sedimentary rock. No granite is an igneous rock. Clastic sedimentary rocks like sandstone form from clasts or pieces of other rock.
