A Further Discussion on Ore-controlling Factors and Genesis of the Dulong Sn-Zn Polymetallic Deposit in Southeast Yunnan |
The Dulong Sn-Zn polymatallic deposit is one of the largest cassiterite sulfide deposits in China. Geological exploration around the Dulong ore district is very important for the continual development of the mining company. Based on the previous exploration and research achievements, this paper discussed ore-controlling factors. It is suggested that this deposit is controlled jointly by Yanshannian granites, the detachment fault system and the Tianpeng Formation. The Yanshanian Laojunshan granites, which seemed to be the most important factor, provided major ore-forming materials and energy; the detachment fault system was favorable for the movement and precipitation of the ore-forming fluid; the Tianpeng Formation offered the profitable physical and chemical conditions for the concentration of ore-forming materials. On such a basis, the authors hold that this deposit should mainly be of magmatic hydrothermal genesis. The ore-prospecting orientations in the area are also pointed out in this paper. |
