摘　　要：石窝地区金银矿主要为构造蚀变岩型矿床,其成矿作用一方面与该区早期的以基底剥离断层为特征的变质核杂岩有关,矿床主要分布在剥离断层控制范围内的岩石中,形成特定的"矿化层位"效应;另一方面金、银矿的最终成矿定位与燕山期岩浆活动及其伴生的脆性断层有关,容矿构造主要为该地区的燕山期脆性断层或剪切带,最终定位的成矿热液主要来自燕山期岩浆岩。The gold-silver ores in Shiwo area are structure-controlled alteration-type deposits. Their mineralization are related to the metamorphic core complex characterized by denudational fault belt in basement rock. The gold-silver ores mainly occur in the range of denudational fault belt, forming the specific ore forminglayer effect. The mineralization is also related to the Yanshanian magmatic activity, which provided accommodate structures mainly consist of fragile faults and shear zone and most part of hydrothermal fluids for the formation of the deposits.
