How is mechanically formed sedimentary rock formed?

I would focus on the general, physical mechanism. Sedimentary rock is formed as a sequence of two processes: * deposition * cementation Deposition means that pieces of minerals – i.e. read more

2 - clastic sedimentary rocks: solids formed of particles of pre-existing rocks, broken and transported generally by moving water (or gravity, or a combination) to a resting spot - typically on the floor of the sea, a lake or pond (or also, in the flood plains and deltas of rivers). read more

Mechanically formed sedimentary rocks are primarily formed by physical, rather than chemical processes. In other words, the components of these rocks are created by the physical breakdown of of other rocks into smaller particles, which then accumulate as sediment, which then becomes sedimentary rock. read more

Rocks formed by accumulation of materials from other rocks which are cemented together. Eg: sandstones formed from sand grains, granite made up of quartz. read more
