Is Granite A Clastic Sedimentary Rock

Various types of clasts are shown in figure 5 12 and in exercise 5 3.

Is granite a clastic sedimentary rock.

It forms due to crystallization from magma. The sedimentary rock becomes metamorphic with heat and pressure. Clastic rocks are composed largely of quartz feldspar rock lithic fragments clay minerals and mica. Conglomerate is a clastic sedimentary rock formed from pre existing.

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. Granite is an intrusive igneous rock formed from the cooling and solidifying of felsic magma at depth within the earth s crust. Clastic rocks are composed of fragments or clasts of pre existing minerals and rock. Clastic sedimentary rocks are composed of other rock fragments that were cemented by silicate minerals.

The smaller ones tend to be composed of a single mineral crystal and the larger ones are typically composed of pieces of rock. The formation of clastic and organic rocks begins with the weathering or breaking down. 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.

If a sedimentary rock consists of the shells of organisms is it clastic biochemical organic or chemical. Sedimentary rocks form as a result of weathering and deposition from previously formed rocks and are usually much softer than igneous or metamorphic rocks. One easy way to. Any type of mineral may be present but they in general represent the minerals that exist locally.

The granite melts into lava then cools becoming igneous. No granite is an igneous rock. Organic sedimentary rocks like coal form from hard biological materials like plants shells and bones that are compressed into rock. Clastic sedimentary rocks are subdivided according to the dominant particle size.

Clastic sedimentary rocks like sandstone form from clasts or pieces of other rock. The spaces between the large angular fragments are filled with a matrix of smaller particles and a mineral cement that binds the rock together. 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. It erodes into sediment and then gets compressed into a sedimentary rock.
