    新疆希勒库都克铜钼矿床成矿地质特征与找矿勘查模型

    Metallogenic geological characteristics and exploration model of Xilekuduke Cu-Mo deposit in Xinjiang

    • 摘要: 新疆希勒库都克斑岩型铜钼矿床是近年来在新疆准噶尔盆地东北缘发现的隐伏矿床。为了理清该矿床成矿特征,构建找矿勘查模型,指导区内找矿,针对矿床的地质特征进行系统的研究,结合矿化特征、蚀变特征、地球化学、地球物理和蚀变矿物分布规律等研究,建立了找矿勘查模型。通过野外地质调查、地球化学、地球物理等勘查研究手段发现,该矿床矿化主要赋存于早石炭世花岗斑岩-花岗闪长岩体及接触带围岩中,深部的花岗斑岩提供成矿物质和流体来源;矿区内北北西向、近南北向断裂及岩体侵位导致的裂隙构造是重要的导矿和容矿构造;土壤中的主要成矿元素具有分带性,地球化学异常、矿化蚀变、高精度低磁异常和激电异常可以圈定蚀变矿化体。矿区地表圈定的1~2 km2的椭圆状蚀变异常内发育的褐铁矿化、细脉状硅化、绢云母化、粘土化、绿泥石化、绿帘石化、角岩化等蚀变,是重要的找矿标志。建立的找矿勘查模型对东准噶尔地区斑岩铜钼矿床及中亚造山带斑岩矿床找矿勘查具有借鉴意义。

       

      Abstract: The Xilekuduke porphyry Cu-Mo deposit is a concealed deposit discovered in the northeastern margin of the Junggar Basin, Xinjiang in recent years.In order to clarify the mineralization characteristics of the deposit, construct a prospecting and exploration model, and guide the exploration in the mining area, this paper focuses on a systematic study on the geological characteristics of the deposit.Using the study of mineralization characteristics, alteration characteristics, geochemistry, geophysics, and distribution of altered minerals, a prospecting and exploration model is established.Through field geological surveys, geochemical and geophysical exploration and research methods, the mineralization of this deposit mainly occurs in the Early Carboniferous granite porphyry granite diorite and contact zone surrounding rocks.The deep granite porphyry provides the sources of mineral and fluid.The fracture structures caused by the northwest and nearly north-south faults and rock emplacement in the mining area are important guiding and hosting structures.The main ore-forming elements in soil have zoning characteristics, and geochemical anomalies, mineralization alteration, high-precision low magnetic anomalies, and induced polarization anomalies can delineate altered mineralization bodies.The elliptical alteration of 1~2 km2 delineated on the surface of the mining area is often accompanied by alterations such as limonitization, fine-grained silicification, sericitization, clayification, chloritization, epidotization, and hornfelization, which are important prospecting indicators.The established mineral exploration model has reference significance for the exploration of porphyry copper molybdenum deposits in the eastern Junggar and the porphyry deposits in the Central Asian Orogenic Belt(CAOB).
