DEFINITION

  • Clastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock. A clast is a fragment of geological detritus, chunks and smaller grains of rock broken off other rocks by physical weathering. Geologists use the term clastic with reference to sedimentary rocks as well as to particles in sediment transport whether in suspension or as bed load, and in sediment deposits. (en)
  • Roches formées par l'accumulation d'éléments provenant de la désagrégation d'autres roches et [qui] peuvent contenir des éléments à granulométrie grossière et très fine.
