clastic rock

There are two types of clastic rock, by shape.

These lower Proterozoic clastic rocks are subdivided into two groups.

A fairly rare form of clastic rock may form during meteorite impact.

Roundness is an important indicator of the genetic affiliation of a clastic rock.

Igneous clastic rocks can be divided into two classes:

Clastic rocks are classified according to their predominant grain size and their composition.

Cements are authigenic minerals precipitated in the pores of clastic rocks.

The two types of rocks found in Santa Cruz are alluvium and clastic rocks.

Shales, sandstones, and conglomerates are all clastic rocks.

Clastic rocks are composed of fragments, or clasts, of pre-existing rock.

Specific rock types in the "continental" northeast, include clastic rocks (sandstones and mudstones).

Clastic rocks have a 'clastic texture', which means they consist of clasts.

Rocks formed by sticking together pieces of previous rocks (clasts) are called clastic rocks.

This technique is particularly valuable for fine-grained clastic rocks such as siltstones, revealing otherwise unseen small-scale sedimentary structures.

These rocks types are usually termed clastic rock, and are further subdivided into fine, medium and coarse grained material.

Again, the small size of many heavy mineral grains means that they are often overlooked and easily underestimated in transmitted light petrography of clastic rocks.

This alluvium is adjacent to and probably underlain by volcanic clastic rock deposited by Mount Shasta in the course of its development.

Particle size, also called grain size, means the diameter of individual grains of sediment, or the lithified particles in clastic rocks.

These carbonate rocks contain variable amounts of chert, and are often interbedded with fine grained clastic rocks.

Masses of salt are pushed up through clastic rocks due to their greater buoyancy, eventually breaking through and rising towards the surface (see salt dome).

Clastic rocks in mafic and ultramafic intrusions have been found and form via several processes:

Many accessory minerals of clastic rocks contain at least traces of rare earth or transition metal impurities and are therefore liable to luminesce.

Peels are mostly used for limestones and calcite-cemented clastic rocks, although cherts and siliceous clastics can be successfully treated.

In sedimentary geology, maturity describes the composition and texture of grains in clastic rocks, most typically sandstones, resulting from different amounts of sediment transportation.

There are also continental clastic rocks of lower Cretaceous age and rocks of marine origin from the Upper Cretaceous.
