Geology of Lesotho only large fault in the country, running northeast-southwest with a vertical displacement of 300 meters near Mafeteng, although there are other smaller faults. More than 50% of Lesotho's territory is underlain by fractured igneous rock aquifers, such as the low permeability basalt of the Lesotho Formation. Dolerite-dike related aquifers have high water productivity in fractures that formed in the surrounding rock due to the high temperature of the intrusion. The sandstones of the Clarens Formation, Elliot Formation and Burgersdorp Formation are small or low quality aquifers, but the Molteno Formation is regarded as the best aquifer in Lesotho with high
