东天山同成铅矿地球化学特征及找矿意义

The Geochemical Characters and Ore Potential Analysis of Tongcheng Lead Ore in Easten Tianshan,Xinjiang

同成地区位于东天山阿齐山-长城山岛弧带(觉罗塔格岛弧),南部有彩霞山铅锌矿,东部有红柳沟铜铅锌多金属矿及维山铅锌矿等。该地区处于新疆重要的铜、镍、金等多金属成矿带,是新疆重要成矿带,成矿条件有利。研究区内元素异常受地层控制明显,主成矿元素Pb、Zn富集度高、范围广,且元素异常整体重叠,所圈定的化探异常与地表发现的铅矿化带走向一致。根据目前取得的化探及找矿成果,认为同成地区具有寻找新型铅矿的较大潜力。

Tongcheng area is located in the Aqishan-Great Wall Island Arc Zone of the East Tianshan Mountains(Juro-tag Island Arc).Caixia Mountain Lead-Zinc Mine in the south side of Tongcheng area,Hongliugou Copper-Lead-Zinc Polymetallic Mine and Weishan Lead-Zinc Mine in the east side of Tongcheng area.The area is located in an important iron,copper,nickel,gold and other polymetallic metallogenic belt,it is an important metallogenic belt in Xinjiang and favorable for metallogenic conditions.Elemental anomalies in the study area are obviously controlled by strata,The main metallogenic elements Pb and Zn has the characteristics of high enrichment and wide range,the element anomalies overlap as a whole.The geochemical anomalies delineated coincide with the trend of the lead mineralization belt discovered on the surface.According to the results of geochemical exploration and prospecting, it is considered that Tongcheng area has great potential to find new lead deposits.
