Residual or Residuum soils are found at moderately deep to very deep layer formed by natural weathering. Colluvium soils are formed from materials transported downslope by gravity.
In soils with distinct soil horizons, the bottom zone is the bedrock denoted as R.

All these soil types have a surface layer or the A horizon. These soils also have subsoils or a Bt horizon, parent material that is A C horizon, and bedrock or the R horizon.

If you are asking for the name of such soils, they are soils formed in residuum, or residual soils. Typically, the soil profile grades into a degraded bedrock called saprolite, with depth, before hiyting hard bedrock.

In soils with distinct soil horizons, the bottom zone is the bedrock denoted as R.
Parent bedrock is an underlying geological material that soil horizons from. Soils inherit a good deal of minerals from the parent materials.

Rocks form soils due to weathering by wind, sun, rain and ice.
