摘要
秦岭地区为我国卡林型金矿重要产地之一 ,矿床明显受地层层位及构造控制 ,呈层状、似层状及透镜状产出。金矿化与硅化、黄铁矿化等蚀变关系密切。成矿流体以渗流热卤水为主。成矿主要发生在印支—燕山期。本文总结的我国秦岭地区卡林型金矿地质特征 ,对寻找此类型金矿具指导意义。
Qinling area is one of the important producing areas of Carlin-type gold deposit in China.Deposits are controlled obviously by stratigraphic horizons and structure and the shapes of Au-ore body are layer and lens.The gold mineralization is closely related to the alteration,especially to the quartzitification,pyritization.The ore-forming fluid is mainly vadose hot brine.The mineralization mainly occurred in India-Yanshan period.The analysis about the geological feature of Carlin-type gold deposit in Qinling area of China is very important to guide the explorer of Carlin-type gold deposit.
