[more ▼] 50 km south of Yaoundé, karst phenomena are developed in micaschists. A network of fractures dependent in thrusting area guided formation of caves, conduits and other morphologies comparable with those found in the karst limestones. The presence of a spring and the proximity of the Nyong river suggest that a chemical erosion within an aquifer is at the origin of most of forms. The position of certain conduits and tafonis dismisses the assumption of a genesis within a weathering mantle.
