Geological Characteristics of Zhaselekule Iron Deposit and its Prospecting Indicators in Xinjiang

摘要: 扎色勒库勒铁矿床处于南天山造山带北部,产于下石炭统大哈拉军山组与石炭纪酸性侵入岩接触带矽卡岩中,铁矿床成矿母岩为钾长花岗岩,成矿方式主要为接触交代作用。围岩蚀变强烈,形成各种矽卡岩矿物组合,与磁铁矿关系密切。该矿床成因类型为酸性岩浆与碳酸盐岩地层接触交代形成的矽卡岩型铁矿床。研究对比发现,可利用地层标志、围岩蚀变特征以及物探异常标志等可作为区域性找矿标志。Abstract: The ore deposits of Zhaselekule of Xinjiang lies in northern part of Southern Tianshan. The ore depos-its are situated in Skarn of the contact zones between the Lower Carboniferous Dahalajunshan formation and acid-ic intrusive bodies in Carboniferous. The ore mother rock is moyite, and main ore-forming way is contact metaso-matism. A variety of Skarn mineral ssemblage was produced with intensive wall rock alteration, and it is closely associated with magnetite. The genetic types of the ore deposit is contact metasomatism Skarn type from the con-nection of acidic magma and carbonate strata. Comparative study found available stratigraphic markers, rock al-teration and geophysical anomaly characteristic signs can be a regional prospecting mark.
