The bentonite deposit is connected to the volcanic rocks of the karroo formation and the bentonite is originated from the metamorphism of the rhyolitic rocks, tuffs and volcanic glass of the second eruptive phase. The thickness of the bentonite layer is varying considerable and is between 2.1 m to 10.6 meters. The overburden from 0.9 to 6 meters. 8
