GEOLOGY

Detailed explanation-1: -cementation, in geology, hardening and welding of clastic sediments (those formed from preexisting rock fragments) by the precipitation of mineral matter in the pore spaces. It is the last stage in the formation of a sedimentary rock.

Detailed explanation-2: -If the sediments are small, they can stick together and form solid rock. This process is called compaction.

Detailed explanation-3: -At the same time the particles of sediment begin to stick to each other-they are cemented together by clay, or by minerals like silica or calcite. This process is called cementation.

Detailed explanation-4: -Cementation: The process by which clastic sediments become lithified or consolidated into hard, compact rocks, usually through deposition or precipitation of minerals in the spaces among the individual grains of the sediment. Compaction: The process of consolidating fine-grained sediments into rock.

Detailed explanation-5: -Cementation happens as dissolved minerals become deposited in the spaces between the sediments. These minerals act as glue or cement to bind the sediments together. The process of sedimentary rock formation takes millions of years to complete only to begin a new cycle of rock formation.
