Geological Characteristics of the Dafulou Tin–Polymetallic Sulfide Deposits in Guangxi, South China

Abstract:

The Danchi mineralization belt is an important ore district in southern China. According to the tectonic characteristics, the Danchi mineralization belt could be devided into three mineralization belts, such as the east mineralization belt, the west mineralization belt and the middle mineralization belt. The Dafulou deposit, which belongs to the east mineralization belt, is located in the eastern flank of the NNW–SSE-trending Danchi anticlinorium. The key structures in the Dafulou ore district are the NW-trending faults, which developed parallel with the axis of the Dachang anticlinorium. In the Dafulou ore district, the Devonian stratum has a closed contact with the Sn–polymetallic deposits. In the Danchi mineralization belt, the granite belongs to alkali-calcium rock series or near to the alkali rock series. There are four different types of hydrothermal alteration, including silicification, carbonation, pyritization and pyrrhotitezation.
