Geological Characteristics And Prospecting Direction Of Pb-Zn Deposit In Yuanjiatun,Heilongjiang Province

Yuan Jia Tun Pb Zn deposit is located in the south of Xiaoxing’an-Zhangguangcainon-ferrous metal iron and copper metallogenic belt,Bindong mineralization area, wherethe tectonic location of Xiao Xing an Ling-the eastern margin of Songnen massif andYichung eosyncline in the west margin of the extension,the area is an importantmetallogenic zone of hydrothermal type and skarn deposit, special tectonic environmentand related magmatic activities,provide favorable conditions for the formation of copper,lead, zinc in the region, ironpolymetallic deposit.Yuan Jia Tun lead-zinc deposit is a recently discovered small deposits and, LowerPermian tu men ling formation is the main host rocks of the polymetallic ore zone in theregion, Yanshan lategranodiorite mineralization were developed in the region.Ore bodiesoccur in tu men ling group of marble and granite diorite contact metasomatism skarn inthe external zone.Under the influence of NNW Yuan Jia Tun faults,the formation of aNorth West to South East to the mineralized alteration zone in the region,in themineralized zone within the eight industrialoutput lead zinc ore.Ore bearing position is thecontact zone and contact zone skarn rock layerlateral tectonic fracture belt.The type ofveinlet disseminated,vein,lenticular.The main metalminerals are alena,sphalerite,chalcopyrite, pyrite etc..The type of deposit is contact metasomatic skarn.Study shows that tu men ling formation area constitute an important geologicalconditions of lead-zinc mineralization,it provided some important material source andmetallogenic environment of copper zinc iron ore.Yanshan granodiorite rocks closelyrelated with mineralization.The great heat of magmatism is the main energy to metalelements dissolved in medium and migration.Rock and stratum contact zone structure,tumen ling formation carbonate formation layer brokenbelt, constitute an important ore controlling conditions in the region of copper zinc iron ore and control the lead-zincmineralization alteration zone and the shape,scale,occurrence and spatial distributioncharacteristics of the ore body.According to the regional geological conditions and prospecting results,this area hasa good prospecting potential further,with good prospects for medium-sized CuPbZndeposits.According to the geological background of the study area,that is looking for thesame type of deposit potential in mining area.
