Comprehensive Information Mineralization Prediction Of Xiaoniuqun Copper And Gold Mine In Inner Mongolia

Copper and gold regional of xiaoniuqun metallogenic belt belonging to the northern margin of North China Craton metallogenic region?II?-Jining-Fuxin Archean Wulashan?Yanshan metallogenic belt of gold silver,iron,copper,lead,zinc,graphite and Muscovite?III?,The middle section of gold and copper metallogenic belt in dashuiqing-reshui?IV?,The southern West of gold and copper metallogenic belt in mingganshan-dashuiqing??₁??he study area is located in the east of the Reshui gold and gold between Kalaqin clear waters,The distribution of a large number of small gold and copper polymetallic deposits.Although the geological background of this area is quite different from that of the Dongfeng and Duqing gold deposits,there are many gold deposits in the southwest of Chifeng,But in a regional geochemical field,There is a similar regional tectonic environment,Intense magmatic activity in Yanshan period in the region,Superiority of metallogenic conditions,Through geophysical and geochemical exploration and the basic work of Geology,Many gold deposits have been found on the surface now,Gold deposits are closely related to NNE,NNW and SN.Mineral?chemical?body and sulfide quartz veins are the main ones,The phenomenon of expansion contraction,branch compound and apex annihilating is common.Research on comprehensive information and metallogenic prognosis in this area,Provide the basis for the follow-up prospecting work?The Middle Jurassic in the study area has a large porosity of acid volcaniclastic rock?imploded breccia and gravel,It is beneficial to the migration and precipitation of gold containing hydrothermal fluids.n the three Permian diorite contact Jinshan formation belt near the high copper background value,It can be used as the favorable source layer for the formation of copper polymetallic ore.The development of multi group ne structure in the area,the main structure is the deep groove boundary fault secondary deep fault,directly controlling rock and controlling basin,part of the fracture directly or indirectly control the formation of scale,shape and occurrence of ore bearing structure and properties;multi period magmatic emplacement,especially in Triassic flash three long rock,late Jurassic and early Cretaceous rhyolitic porphyry granite porphyry ore source or heat source can provide respectively for each period of copper polymetallic ore or silver ore formation.Through comprehensive research and analysis,the alteration that is closely related to gold mineralization is mainly faded,silicified,red and sericite,and more commonly known as"burning skin".The alteration is closely related to copper polymetallic ore,which is silicification,chlorite,epidote and carbonation.The low and high magnetic anomaly zone is weakly positive and negative abnormal contact mineralization favorable areas for ore prospecting is high magnetic anomaly mark.Resistivity is greater than500?·m,The polarizability is greater than that of 2.0%,The characteristics of high?middle?resistivity and high polarization are important electrical prospecting indicators for gold prospecting in mining area,and relatively low resistance and high polarization anomalies at fault junction sites,which are also important prospecting indicators.Large area,abnormal high value,obvious zoning and obvious concentration centers of Au anomaly is the direct prospecting exploration marks,and Au associated As,Sb,Hg and other elements is abnormal ore prospecting and indirect prospecting.Based on the preliminary data collection,according to the development scale and concentration degree of mineralization alteration belt,combined with the metallogenic geological conditions for mineralization of each genetic type,three prospecting targets in the area of the?gold deposit are established,The Xiaoxigou section,dasonggou section,dabeigou-dalianggou section.There are one target areas of copper polymetallic ore prospecting in zone II,The luoboqigou section.Geological and geophysical and geochemical conditions for the formation of a small medium temperature hydrothermal vein type copper polymetallic deposit in luoboqigou Section,The outer circumference still has a great exploration space?The surrounding rock is volcanic breccia and sand conglomerate in xiaoxigou and dasonggou Section,The mineralization body is influenced by the porosity of the surrounding rock,the general grade is lower,the mineralized alteration is wider,and the wall rock alteration zoning is not obvious.The surrounding rock is rhyolite in dabeigou and dalianggou Section,The grade of mineralized body is high,the mineralized alteration is narrower,the alteration of surrounding rock is more obvious?...
