The Study On Copper-molybdenum Polymetallic Mine Control Over Rocks And Ore-controlling Structure And Mineralization Forecast Of The JiuDingshan

The nine Hill copper-molybdenum polymetallic mine located in Midu County of Yunnan Province.Located Sanjiang metallogenic belt southern section.Typical copper-molybdenum deposits in porphyry-related activities.Mine is located between the Erhai Lake-Red River fault with the way the sea-Binchuan fracture.Lijiang-Heqing porphyry-type Cu-Mo-Au ore concentration area. and alkali-rich porphyry concentrated area.Mineralization geological conditions and prospecting potential is very good.Magmatic rocks in the mining area is more developed. complex rock types.The magma experienced several activities.From the the syenite porphyry changes to porphyritic granite. Then becomes granite porphyry. finally becomes alkali feldspar granite.Experienced a total of four evolutionary process.Second. three magmatic rocks and ore formation is closely related.The third of the alteration is strongest. lead to the formation of copper. molybdenum. gold.Mine complex tectonic setting. Intense tectonic activity.Jinsha-Ailao Shan fault zone occur over large-scale sinistral strike-slip shearing in the Himalayan period.Form a set of large-scale strike-slip fault system that Control the spatial distribution of the alkali-rich porphyry belt of the mine north western trending in the Himalayan period. Mine fold deformation structures control the main mine rock mass is Machangqing alkali-rich porphyry body of Himalayan period. Morphology and distribution of dykes. North West to the fracture to the Jinsha River-Ailaoshan and Xiangshui fault Control of the rock mass and the distribution of the ore body.The mine’s main ore-ore-controlling structure is alkali-rich porphyry body Of Machangqing and wall rock contact zone. Ore-controlling structure types include five categories.They are the control of the North East to the north west of the main faults of the ore zone; rock body structure fractured zones; structure of the contact zone; fissures (joints-cleavage fractured zone) on the control of the orebody; late tectonic mineband and the destruction of the ore body.Machangqing alkali-rich porphyry body of Himalayan period control of the mine. Porphyry copper (molybdenum) mineralization are mainly present in the alkali-rich porphyry body internal fault or fracture controlled by tectonic fissures of the rock mass. Skarn and hornfels-type copper (molybdenum) mineralization in the presence of alkali-rich porphyry body. Machangqing outer contact zone. the the orebody shape of the rock mass and wall rock contact zone shape control. The body of gold mineralization in the Ordovician sunny Formation and Lower Devonian system Kang Gallery Formation by fracture zones. the slippage between layers with or the tensile fractured zone control.In summary. After the study of the geological background of the mine area. the geological features. Analysis of the major structural features of the mine and its control rock and ore-controlling characteristics Summarizes the metallogenic regularity of copper. molybdenum. gold in mine. Combined with Prospecting logo of geological. geophysical. geochemical and remote sensing.I delineation of the two target volumes in Nine Mountain Mining Limited range of mining rights.The delineation of the two targets in the ore zones within.
