Sedimentary rocks with names

Sedimentary rocks make up 75 percent of the rocks at the earth's surface but only 5 percent of the outer 10 miles of the earth. Sediment, as distinguished from sedimentary rock, is a collective name for loose, solid particles and is generally derived from weathering and erosion of preexisting rock.

Rock permeability depends on ambient pressure, temperature and deviatoric stresses. In sedimentary rocks the permeability is affected by quartz content, gravel fractions and grain sorting. There are two different permeability models for rocks: the capillary model of pores and the fracture model.

Sedimentary rock - Classification, Deposits, Types: In general, geologists have attempted to classify sedimentary rocks on a natural basis, but some schemes have genetic implications (i.e.,knowledge of origin of a particular rock type is assumed), and many classifications reflect the philosophy, training, and experience of those who propound them.Following are the two types of igneous rock: Intrusive igneous rock: These rocks crystallise below the earth’s surface resulting in large crystals as the cooling takes place slowly.
