1. n. []

Silica-based, noncarbonaceous sediments that are broken from preexisting rocks, transported elsewhere, and redeposited before forming another rock. Examples of common siliciclastic sedimentary rocks include conglomerate, sandstone, siltstone and shale. Carbonate rocks can also be broken and reworked to form other types of clastic sedimentary rocks.
