    Gabrovšek, Franci, 1968- ...
    During November 1996, group of 4 researchers from Slovenia and 4 researchers from China worked in the area of Tian Sheng Qiao - Natural Bridge, north of Liupanshui, NW Guizhou in China. In this paper ... are presented some results made by joint team in few days. The geomorphological mapping of about 2 km2 big area, exploration of three caves and their mapping, some measurement of main structural elements on the surface and in the caves, litology analyses, x-ray of sand and chemistry of the water from Swallow cave were done. The surface is well karstified, but shows surface fluvial forms, among which the deepest is the canyon of the Gan He river, which flows under the natural bridge. We visited seven caves but because of the lack of time and equipment we were able to survey only three of them. Cave system, and collapse depression between them are strongly related to main faults and fissures directions.
