Gejiu Tin Mine is located at the southern edge of the Zhengnan and Yungui Plateau in Yunnan Province. The surface of the mine exposes the Mesozoic Triassic Carbonate layer with a thickness of 3,000-5,000 meters and is located at the intersection of three regional large structural lines, namely: Northwest Sichuan-Tibet Yunnan-Myanmar giant zigzag structural belt, north-south Sichuan-Yunnan deep big fault zone and east-west south ridge zone. Large tectonic framework of the mining area, Proterozoic and before that has been formed, the north west side of Kang Dian axis, south east neighbor more
