Abstract:

Songshudaban gold deposit in Yanqi County is located in the middle part of the Southwest Tianshan of Xinjiang gold polymetallic metallogenic belt，and near north margin of suture zone between the Tarim plate and Kazakhstan-Erie plate.Songshudaban gold deposit produced in the Sahentuohai-Dashankou brittle-ductile shear zones.The ore-bearing rock are a set of fine clastic rocks and quartz veins from the middle Devonian Saaerming formation.The NW and NWW trending faults developed in the mining area，and metallogenic geological conditions are superior.1∶10 000 geological survey，1∶10 000 soil geochemical survey and explora-tory trench reveal，and other works have been carried out in the area.Four gold orebodies were found，but these orebodies have the features of small scale，low grade and extends unsteadily，the prospecting results are not outstanding.To identify abnormal sources of soil geochemical anomalies and search mineralized rich areas of gold，expand the size of the existing gold orebodies or find new gold orebodies in Songshudaban area，the 1∶2 000 rock geochemistry profile measurement were carried out，two primary halo comprehensive anomaly zones of Au，As，Sb，Hg，Cu，Bi with NWW trending were delinead.The anomalies are mainly distributed in limonite mineralized，kaolinized sericite phylliterelated to ductile shear zone.The mineralization and alteration of sericite chlorite slate，andesite porphyry，marble and other strata on both sides of the shear zone is relatively weak.After anomaly verification，three new gold orebodies and mineralization spots were found.The engineering control gold orebodies are 60~120 m long and 1.00~3.25 m thick with a grade of 0.65×10^-6~2.85×10^-6，it means that the good geochemical anomalies and ore prospecting results have been achieved.According to the features of rock geochemistry and gold mineralization，it is believed that the first subgroup of middle Devonian Saaerming formation is the favorable strata for searching gold deposits，and it is very important ore-searching criteria.The gold deposit is strictly controlled by ductile shear zones.There is great potential to find ductile shear zone gold deposits in Songshudaban mine area.

Key words: rock geochemistry, profile measurement, characteristics of geochemical anomalies, ductile shear zone, Songshudaban gold deposit, Yanqi County, Xinjiang
