The Mandhip Khol-Pyton cave, located in an area declared Protected Forest in the Rajnandgaon District about 7 km in a direct line wNw from the village of Thakurtola (N21°39’:E080°58’), consists of an upper level orientated essentially along NE-SW and NNW-SSE fracture systems, subsequently connected through a NE-SW structure with an independent karst system, at a lower level orientated predominantly along bedding planes. The speleogenesis controlled by various structural elements has manifested itself as having different morphologies in the two levels. In fact, fracture-controlled vadose passages prevail in the upper level, while water flow along the bedding planes in the lower level caused morphologies characterized by wide but low passages. The studied system constitutes a particular example of karst morphologies developed in a lenticular limestone formation within phyllite rocks of Precambrian metamorphic age.
