How Clastic Sedimentary Rocks are Formed: Pre‑existing rock undergoes chemical and mechanical weathering by roots, acid rainwater, gravity, wind, and water. The broken particles are carried through water or air until they settle out in a lower area when the current wasn’t fast enough to carry the particles.Sedimentary rocks are categorised according to the mode of formation into- A. Those formed chemically: Mineral-containing water evaporates at the mouths of springs or salt lakes, forming stalactites and stalagmites which are the deposits of lime left over by the lime-mixed water as it evaporates in the underground caves.Breccia forms where broken, angular fragments of rock or mineral debris accumulate. One of the most common locations for breccia formation is at the base of an outcrop where mechanical weathering debris accumulates. Another is in stream deposits a short distance from the outcrop or on an alluvial fan. Some breccias form from debris flow deposits.Conglomerate is a clastic sedimentary rock made up of rounded clasts that are greater than two millimeters in diameter.
