1. Pertaining to fragments (such as mud, sand, and gravel) produced by the mechanical breakdown of rocks. 2. A sedimentary rock composed chiefly of consolidated clastic material.

pertaining to a sedimentary rock composed principally of fragments derived from pre-existing rocks, rather than chemical precipitates.

formed from fragments of pre-existing rock transported and deposited

sedimentary rock a sedimentary rock composed of fragents of rocks/minerals (clasts)

Said of rocks composed of particles of other rocks or minerals, including broken organic hard parts as well as rock substances of any sort, transported and deposited by wind, water, ice or gravity.

of or belonging to or being a rock composed of fragments of older rocks (e.g., conglomerates or sandstone)

consisting of fragments of rocks or of the hard parts of organisms.

Being or pertaining to a sedimentary rock composed primarily from fragments of preexisting rocks or fossils.

A general term used in sedimentology to describe mineral and rock fragments in sediments/sedimentary rocks that have been derived from pre-existing rock. Rock and mineral fragments in this context may be referred to as clasts.

A sedimentary rock composed of fragments (clasts) of pre-existing rock or fossils. (=Detrital sedimentary rocks)

Clastic - A rock made up of fragments (clasts) of pre-existing rocks, such as sandstones that are made up of fragments derived from igneous rocks such as granite.

A sedimentary rock mostly composed from fragments of the parent material & deposited by mechanical transport.

broken fragments of pre-existing rocks; sandstones are clastic rocks

Pertaining to a rock or sediment composed primarily of fragments derived from pre-existing rocks or minerals and transported from their place of origin.

Fragments of rocks that have been moved individually from their original place of formation

detritical rock composed of angular or more or less rounded rock or mineral fragments deriving from degradation of older rocks, mainly by erosion.

Composed of broken fragments that have been derived from pre-existing rocks by weathering and erosion and transported some distance from their place of origin

Rocks built up of fragments of pre-existing rocks which have been produced by the process of weathering and erosion and in general transported to a point of deposition.

Pertaining to a sediment or rock composed chiefly of fragments derived from pre-existing rocks or minerals;

Rock that consists of fragments of older rocks.

Made up of pieces (clasts) of older rock; rock derived from mechanical processes; generally sandstone, siltstone or shale
