During which stage of sedimentary rock formation do minerals crystallize at points of contact with other clasts? a. deposition b. cementation c. transportation d. burial

B. Cementation

Explanation:

The processes by which sediments are changed into rock are complex, but can be simplified into two processes, called compaction and cementation. Rounded sediment grains (ooliths) bound together with crystalline calcite.

The correct answer is option B, that is, cementation.

Explanation:

The procedures by which the sediments are modified into rocks are composite, however, can be simplified into two procedures, known as cementation and compaction. In geology, cementation refers to welding and hardening of clastic sediments, that is, those produced from the preexisting fragments of rocks due to the precipitation of the mineral matter in the pore gaps. It is the ultimate phase in the production of sedimentary rock.
