Clastic rock

Clastic sedimentary rocks are rocks composed predominantly of broken pieces or clasts of older weathered and eroded rocks. Clastic sediments or sedimentary rocks are classified based on grain size, clast and cementing material ... The most common stable mineral in siliciclastic sedimentary rocks is quartz (SiO 2).
