Explanation
Clastic sedimentary rock formed by sand cementation and curing. The detrital components such as quartze and feldspar account for more than 50%, and the particle size is 0.05~2mm. It is formed by weathering, denudation, transportation, sedimentation, cementation, curing and diagenesis of the surface rocks of the crust. It consists of two parts: debris and filler. In addition to quartze and feldspar, there are also muscovilte, caldte, clay mineral, dolomite, magnetite, etc.
