Relationship between geological structure and mineralization of mercury-lead-zinc deposit in the Fenghuang area

Mercury-lead-zinc deposit is the dominant mineral in Fenghuang area of Hunan Province. Combined with the actual geological data, this paper introduced the basic geological characteristics and types of mercury-lead-zinc deposit. In addition, the tectonic control factors of mineralization were analyzed, and structural ore-controlling regularity was initially proposed. Mineralization types of mercury-lead-zinc deposit in the study area are stratabound superimposed (sedimentary reformation) deposit and mesothermal-epithermal filling of fault fracture zone vein deposit. The structure as the passageway for ore fluids of mercury-lead-zinc deposit is the NNE and NE regional faults (Baojing-Tongren fracture), and the controlled ore structure is the NNE and NE anticlinal core, two wings and the turning parts of anticline and syncline. Besides, the ore-hosting structure is NW small faults, let seam joints, interlayer fracture and fracture zone.
