Deep Mineralization Laws and Fitting of Ore Controlling Fold Axes in the 16th Penggong Section of the Woxi Gold-anti-mony-tungsten Deposit in Hunan Province
The Woxi gold-antimony-tungsten deposit belongs to the medium low-temperature hydrothermal quartz-vein-type de-posit,and the distribution of the ore body is strictly controlled by the structure.Through comprehensive analysis of deep structures,ore body characteristics,and ore control laws,it is believed that the deep V3 and V8 veins in the Shiliupeng Gong ore section are mainly controlled by the Woxi West syncline and the Woxi large fault.The ore body mainly occurs in the interlayer slip zone of the West syncline and is approximately parallel.Research has shown that the westward inclined fold belongs to the oblique oblique fold,and it slopes from NE to NEE,with an axial plane inclined to-wards NW-NNW and an inclination angle of 25°～60°.Based on the V3 and V8 veins exposed underground,fold hubs at different depths were determined.On this basis,an axial model of the ore controlling folds in the 16th Penggou mining section was estab-lished,providing a theoretical basis for further exploration and comprehensive research in the mine.
