Description :
Most pediments in the Gongola Basin are developed on bedrock. Field observations indicate erosion processes which have been affected by climatical dry conditions of the Late Pleistocene. Since that time, edaphical dryness on the pediment surfaces has been responsible for traditional continuous relief-forming processes also during following humid periods of the Holocene. Since the younger Holocene, erosion has been supported by anthropogenic influences.
