Is Granite A Clastic Sedimentary Rock

Clastic rocks are composed of fragments or clasts of pre existing minerals and rock.

Is granite a clastic sedimentary rock.

Breccia is a term most often used for clastic sedimentary rocks that are composed of large angular fragments over two millimeters in diameter. Granite is an intrusive igneous rock formed from the cooling and solidifying of felsic magma at depth within the earth s crust. Clastic sedimentary rocks are classified according to the grain size of the sediment and the kinds of rock fragments that make up the sediment table grain size is largely a function of the distance the particle was transported. If a sedimentary rock consists of the shells of organisms is it clastic biochemical organic or chemical.

Clastic sedimentary rocks are subdivided according to the dominant particle size. No granite is an igneous rock. It forms due to crystallization from magma. 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.

One easy way to. It erodes into sediment and then gets compressed into a sedimentary rock. The formation of clastic and organic rocks begins with the weathering or breaking down. Various types of clasts are shown in figure 5 12 and in exercise 5 3.

Clastic sedimentary rocks like sandstone form from clasts or pieces of other rock. The granite melts into lava then cools becoming igneous. 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. The sedimentary rock becomes metamorphic with heat and pressure.

The spaces between the large angular fragments are filled with a matrix of smaller particles and a mineral cement that binds the rock together. Clastic sedimentary rocks are composed of other rock fragments that were cemented by silicate minerals. Conglomerate is a clastic sedimentary rock formed from pre existing. Any type of mineral may be present but they in general represent the minerals that exist locally.

The smaller ones tend to be composed of a single mineral crystal and the larger ones are typically composed of pieces of rock. Clastic rocks are composed largely of quartz feldspar rock lithic fragments clay minerals and mica. In general the greater the distance traveled the smaller and more rounded the sediment particles will be. Sedimentary rocks form as a result of weathering and deposition from previously formed rocks and are usually much softer than igneous or metamorphic rocks.
