Sedimentary rock

Sedimentary rocks are the result of the accumulation and compacting of mineral debris (i.e. other stones), organic debris (animal remains and vegetation, fossils), or chemical precipitation.

They are exogenous rocks, i.e. rocks which are formed on the surface of the Earth. Sedimentary rocks are present on 75% of the surface of the Earth's continents, but when considering its crust as a whole (from the surface to a depth of 22 miles (35 km)), they only represent 5% of its total volume.

The main sedimentary rocks are:

  • sandstone
  • sand
  • siltstone
  • loess
  • clay
