Clastic Sedimentary Rock Classification

Sedimentary rocks are classified on the basis of the texture (grain size) of the rock, and composition. The basic classification only concerned texture, using the Wentworth size scale.But any full rock name must specify both texture and composition. Thus, an arkose sandstone is a rock of sand sized particles, with a high percentage of those particles being feldspar.

Sedimentary Rocks Lesson #13 Oregon State University

Sedimentary rocks are formed in three ways from these different sized sediments. A sedimentary rock is a layered rock that is formed from the compaction, cementation, and the recrystallization of sediments. Compaction is the squeezing together of layers of sediment due to the great weight of overlying layers of rock.

Organic Sedimentary vs. Chemical Sedimentary Rock Sciencing

Organic. Organic or biological sedimentary rocks are formed by living organisms, typically when the remains of living organisms build up and are compacted by sediment. Coal, for example, is made from long-dead vegetation crushed by thick layers of sediment and

Origin and Classification of Sedimentary Rocks

Identifying Clastic Sedimentary Rocks. The basic criterion for classifying clastic textures is grain size, with subordinate subdivisions made on the basis of rounding, sorting and cementation . Particles are referred to as coarse grained (over 2mm in diameter), medium grained (1/16 to 2 mm in diameter),
