| Gold mineralize section of fuxing-duhuangling in Yan bian is located thesouth of peace and tranquility mountain intumesce belt and the east of Jurassicsystem volcano-hypo-volcano structural magmatic rock belt in the Middle EastYanbian. And its physical position is E: 130°22′30″~130°37′30″,N:43°17′00″~43°22′30″。There are big, suffer and minitype golddeposit and 30 mineral occurrence. It is importance area ore-direction amongMesozoic volcano hydrothermal gold mine in east of my nation, mineralresources potential is grestness.The deposit is located in the conjunct area between the Paleozoic E-Wcontinental margin active belt of Siberia to North China plates and metaphaseCenozoic N-E continental active belt of west Pacific.Mineralize section and mineralize is relation with suffer-late Jurassic—early Cretaceous volcano magma activity, controlled area gathered EWstructure magma belt of baicaogou-xiaoxi'nancha and near SN crack.Hypo-lava controlled by volcanic institution more submit small stock. It'ssequence is granule diorite, quartz dioritic porphyrite and plagio granite-porphyry, and quartz dioritic porphyrite is osculation with Au mineralize,mostly the condition of ore-controllability. Autoecious crypto-explosivebreccia canister and periphery crack endow gold ore body. Petrochemistry indicate that hypo-lava is suffer kalium partialalkalescence autunite alkalescence rock, from west to east of district it seriestransfer from abundant alkalescence high kalium to feebleness alkalescencesuffer kalium and litmusless to suffer acidity rock series; lanthanon distributemode and isotope testing indicate that magma root deep upper mantle, take oncharacter of same fountain, same member, same evolvement, take oncoherence in cause of formation; microelement Au, Ag etc. correlationalvariety indicate that rock-grown epoch is same with ore-grown epoch,ore-grown and volcano magma activity take on coherence in time. Form investigating employment indicate: the EW baicaogou-xiaoxi'nancha deep big crack control volcano-hypo-lava structure magma beltin space; the position of the conjunct between EW rift (belt) and SN rift andNE crack control volcanic institution and the center of volcano out-break;diggings brecciated structure of volcanic institution and periphery crackendow gold ore body. Accordingly, it make of the current section importancediffer level structure condition ore-controllability. Quartz dioritic porphyrite submit small stock, it is relation withore-direction, and submit volcano-neck phase, and concomitant with crypto-explosive breccia canister. Controlled by region structure, quartz dioriticporphyrite take on disciplinarian of similar rank space in EW direction, itmake up of absolutely necessarily magma condition in search of gold mine inmineralize area. Ore body mostly submit anomaly veins, vesica; primary ore types ofmineralization section is native gold+ brazil + enargite + copper pyrite ore,and brazil + arsenikstein + native gold ore. Ore structure mostly is cross veintexture, crushed texture, vein-stockwork and brecciated structure etc. Fromcenter forth is silicification, pyritization, sericitization, jarositizationchloritization and kaolinization. So you say ore body inner-exterior character...
