Classification based on grain size. Clastic (those composed of rock fragments) sedimentary rocks can be classified as: conglomerates. sandstones. siltstones. shales. claystones. Prefixes can also be added to indicate the dominant mineralogy.

2000-10-26 · A good classification is based on some theory that explains how the rocks form, and are related to each other. We want to group together rocks that form by similar processes. The most general theoretical model we have for sedimentary rocks is the simple ideal model.The basic classification is based on that model.

sedimentary rock - sedimentary rock - Classification systems: 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.

2000-10-26 · 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.
