The Analysis Of Ore-controlling Structure And Target Section Forecast Of The Ⅶ Ore In Qinghai Qimantage Hutouya Orefield

The Hutouya polymetallic deposit is located in the north slope of the Qimantage Hill inEast Kunlun, north of the East Kunlun fault,north of the Nalingguole river fault.The tectonicposition is in the North Qimantage early Paleozoic magmatic arc and Qimantage earlyPaleozoic suture zone.The deposit is located among east longitude91°30’-91°49’,northlatitude37°02’-37°06’,with a total area208km2,which is one of the more significant depositsin Qimantage area. Select hutouya typical structural development within the ore field researchⅦore constructed ore control, aims anatomy special belt within the typical Orefieldore-controlling structure to build the initial ore controlling structure-prospecting model todetermine prospecting signs, forecast prospecting targets, similar studies in the region toprovide a technical basis for the deposit, to make recommendations on the ore field andprospecting work week adjacent areas.We have did a lot of field research and many indoor analysis research work on Hutouyapolymetallic deposits, and made the following progress and achievements:1.We have carried out a detailed structural features characteristic analysis of Ⅶ orebeltin Hutouya ore field. The ore-controlling structural system is divided into EW, NEE and nearthe north-south three groups.2.We made the sub-division of Ⅶ mineralized zone ore-controlling structure: TheStructure before the mineralization period is the deep regional faults. The Mineralizationtectonic metallogenic period or earlier formed EW trending F5, F6. The structure afterMineralization constructed is the north-east, north-south faults.3. The Ductile shear zone which developed between C1dg and Jxl is real after we did thefield research, statistics joints and ductile deformation analysis.4. The mineralization superimposed features of Hutouya Orefield Ⅶ belt type: skarn+fracture zone superimposed hydrothermal type, instead of stratabound type.5. We did the deep and prospecting target forecast by combining geophysical dataanalysis and Ⅶ belt tectonic features of the study area. There are four class Ⅰt argets,two class Ⅱ targets and two class Ⅲtargets.
