Sedimentary rock - Wikipedia

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of small particles and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment ...

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.
