| Gaoling Gold Mine of Muping District,Yantai City,Shandong Province Located in the west of the northern section of the gold belt of Jiaodong East Mou(Ping)-Ru(Shan).Fracture structure development?Magmatic activity is high? Good ore-forming conditions of gold deposits in the region.There are small gold mines such as Shuangshantun Gold Mine and Xiayu Village Gold Mine and many gold ore sitesc,It shows a good metallogenic background in the area.The Shuangshantun gold deposit is an old deposit.Infrastructure began in 1993 and was rectified in 2013.It did not carry out mining.The proportion of reserves at the third level in the mine was unbalanced,the capacity of resource continuity was insufficient,and the mine faced the dilemma of scarce resources.Mining gold mining has a long history,and There are a large number of pits in the surface exposed area.Fracture structure development in the study area,NE,NNE and NW Among them,the NE and NNE faults are the most developed,and they run through the whole area.They are closely related to the formation of gold mines,and the characteristics of ore control structures are obvious.It is necessary to conduct in-depth exploration,especially the lack of detailed work on the laws of deep metallogenesis.The study on the metallogenic law of Shuangshantun mining area,especially the deep hidden ore body,has far-reaching significance for the construction and stable development of the mine.This paper analyzes the ore body distribution and the characteristics of ore control structure in the Shuangshantun mining area within the Ecliptic?Beltand Blind Eclipse Belt below-500 M.Explore new resource reserves.The following key results have been achieved:1?The metallogenic rock mass in Shuangshantun Gold Mine is basically the same as the Sanshandao Gold Deposit in Jiaodong,and belongs to the "Jiaojia type" altered rock type.In addition to silicification and sericite alteration,the alteration type of Shuangshantun Gold Mine is also seen in albite Mineralization alteration.When polymetallic sulphides occur in altered rocks,gold ore bodies are often formed,which is a direct sign of mineral prospecting for deposits.2?The mineral body is strictly controlled by the structure,and the change of the mineral body production form changes with the change of the fracture production form.In the fault cross composite site,it provides favorable ore-forming space for the formation of mineral deposits,especially the tectonic trend and tendency to produce changes and the eroded rock expansion complex area.It is easy to form industrial ore bodies with large thickness and high grade.3?below-500 M is the second concentration zone of gold in the deep part of the mining area.Under the elevation of-900 m in the mining area,the blind erosion zone is still deep and is affected by the structure.The gold ore body controlled by the deep part of the drilling project is not closed.Moreover,the deep part of the gold ore body and the shallow part of the production are inconsistent in the upward movement.The deep ore body is not closed and there is still a good prospect for prospecting. |
