CoachClastic sedimentary rock texture is also influenced by factors such as mineral composition, sorting (uniformity of particle size), rounding (degree of edges and corners), and grain angularity (shape of grains). These factors can provide information about the energy of the environment where the rock was formed.

Is conglomerate a clastic rock?
No, conglomerate is a sedimentary rock composed of rounded rock fragments cemented together. Clastic rocks are composed of individual grains or fragments of minerals or rocks that have been compacted and cemented together.
Is bituminous clastic?
Bituminous is not clastic, as clastic refers to sedimentary rocks composed of fragments of pre-existing rocks. Bituminous, on the other hand, is a type of coal formed from the compression and heating of organic matter.
What type of sedimentary rock is chalk clastic chemical or organic?
Chalk is a type of sedimentary rock that is primarily composed of organic material, specifically the calcareous remains of marine microorganisms such as coccolithophores. It is not considered clastic, as it does not consist of fragments of pre-existing rock like clastic sedimentary rocks.
List three major groups of sedimentary rock?
Clastic sedimentary rocks: Formed from the accumulation of mineral and rock fragments that are cemented together. Chemical sedimentary rocks: Formed from precipitation of minerals dissolved in water. Organic sedimentary rocks: Formed from the accumulation of organic material, such as plants or animals.
How do geologist classify sedimentary rocks?
They are classified as clastic or non-clastic. Clastic sedimentary rocks are formed from rock particles of various sizes. Non-clastic rocks are formed from precipitation of minerals out of solution or by the lithification of organic matter.
