Mineralization Characteristics And Prospecting Direction Of The Weishahe Iron Polymetallic Deposit In Linjiang City,jilin Province

The weishahe iron polymetallic deposit is located in the southwest of the Dalizi iron deposit,which belongs to the periphery of the Dalizi iron deposit in district.The newly discovered iron ore body in this study area broke the previous understanding in depth and opened up the second space for the exploration of iron ore body;And the silver-polymetallic ore belongs to the first discovered large-scale ore body in the Dalizi region,breaking the single situation that only the iron ore body exists in the Dalizi region.The discovery of the weishahe iron polymetallic deposit has far-reaching significance for solving the resource crisis of the Dalizi iron mine.This paper which comprehensively collecting,sorting and contrast research predecessors' information,taking modern deposits science,metallogenic prediction theory as the instruction,basing on geological survey,drilling,pit and tunnel geological record,using the geotectonics,petrology,mineralogy,deposits and other multidisciplinary analysis method,combining geochemical characteristics of rare earth elements in the Dalizi strata with metallogeny research,summarizes the deposit geological characteristics,metallogenic regularities and prospecting indicators,and determines the prospecting direction.The overland strata of the deposit are simple,and the structure developed.According to the degree of engineering control and research,the genetic type of silver-polymetallicdeposit belongs to the carbonate silver deposit.The iron deposit belongs to the Dalizi type iron deposit,which is similar to the Xiaolizi type iron deposit in terms of ore features and occurrence rules,and belongs to the sedimentary metamorphic carbonate type iron deposit.This paper comprehensively studied the regional low-delay magnetic anomaly,the original rock property of the Dalizi formation,the geochemical characteristics of the rare earth elements in the Dalizi formation,the genesis of the deposit,the occurrence law of the ore body,and the ore prospecting signs,and pointed out the direction for future deep and peripheral prospecting work in the Dalizi region.
