Abstract

Pa Ben gold mine is located in the contact belt of the Gondwanaland and Laurasialand. The North West part of Laos Bau County is connected with the Sanjian fault belt in western Yunnan Province. The running of the Pa Ben gold mainly occurs in the Permian limestone, and the adjacent contact zone. By studying the fluid inclusions and deposits role geological features of Pa Ben gold mine, it indicates that the metallogenic salinity is lower than that of the basin brine salinity (greater than 20%), and the fluid temperature is between 140 and 295 DEG C, the characteristics of metallogenic depth is less than 1 km. Considering that the gold mine are subjected to the ductile-brittle shear deformation stage, the early stages of mineralization, the main mineralization stage, the late stage, and the late tectonic activity stage, which can broke into five mineralization stage in the area. It is concluded that the genesis of the ore deposit belongs to the typical magmatic hydrothermal gold ore deposit of the middle-low temperature.
