OFR19 Regolith Thickness of the Delaware Piedmont

OFR19 Regolith Thickness of the Delaware Piedmont

This map shows the total thickness (regolith) of both the loose, transported material and the weathered rock that overlies crystalline rocks of the Delaware Piedmont. Transported material is generally thin and the weathered rock in place (saprolite) usually makes up the bulk of the regolith. Saprolite may vary gradationally from a weathered rock that has retained much of the characteristics of the parent rock to a product mineralogically and texturally different from its source rock.
