The Geological Characteristics Of Gold Mine And Its Factor Analysis Of Ore-controlling Structure，the Southern Part Of Ailaoshan Orogenic Belts

The research of the type orogenic belt gold is a hot issue for tectonic geology res-earch in recent decades, At the same time Ailaoshan gold ore belt is one of the mostimportant gold mine prospecting and production base in southwest area of China.This paper aims to study the geological characteristics of gold mine and its factor an-alysis of ore-controlling structure，the southern part of Ailaoshan orogenic Yunnanprovince systemly,on that basis use the knowledge of Geological Sciences、structuralgeology、mineral deposits、sedimentology comprehensively,and use the latest theoryin orogenic belt research and Geological prospecting to discuss the con-tor action ofstructure on gold mineralization in the research area.On the field investigation and study of gold ore belt,the southern part of Ailaos-han,on mineralization geological features.deposit types,orebody characteristics,ore ch-aracteristics,origin of metallogenic materials,ore-forming age and regional structure,magmatic rock, formulate the relation between material sources of gold mineralizati-on and the material wich is rised from deep underground with interaction of crust andmantle, the characteristics of ore-forming fluids,and the relationship between the unu-sual on chemical elements and gold mineralization and so on.On the basis of the factthat the unusual on chemical elements is usually gold form area, we could find unkno-wn gold mineral more easily.We find the relationship between stratum and gold mineralization is not obviousby studying the type gold ore this research erea and analysising the other ores this are-a；however the relationship between magmatic rock and gold ore is very close,and theplace of gold mineralization is ofen where the magmatic exsists,even some rocks the-mselves are ore because their gold content is very high,and it makes clear that magm-atic rocks provide the source for gold mineralization; We also find that the place whe- re the magmatic rocks and the gold ore exist is often together in fracture zone,their sh-apes appearing ribbon pattern,lensing,schistose and so on,and their major axis directi-on being NW-SE,which is similar with the tectonic line this area.It explains that the p-laces and the shapes of the glod ore and the magmatic rocks are obviously controledby structure this erear.In addition,the types and the material source are also controledor affected by the structure,all this reveal that the characteristic of gold ore this area.Through the summary that the relationship of structural evolution is very closely.Mantle materials rise into crust through the fracture forming a variety magmatic rocksand gold mineralization is occurring at the same time.At last,I make a few suggestio-ns for prospecting this area.
