摘要
通过对铧厂沟金矿床矿区地质、矿床地质以及矿石类型、矿石矿物、矿石组构的研究,认为铧厂沟金矿床的形成至少经历了基性火成岩和凝灰质绢云千枚岩的退化蚀变作用期,构造热液矿化蚀变作用期和表生氧化作用期的三个主成矿演化期。
Based on the study of ore area geology and ore deposit geology in the Hua-Chang-Gou gold mineral deposit, especially according to the characteristic of ore type, ore mineral, ore fabric and metallizing alteration,it was concluded that the formation of Hua-Chang-Gou gold ore deposit came through at least three main metallogenesis phases:(1) metallizing alteration of basic igneous rock and tuffaceous sericitic phyllite; (2) tectonic hydrothermal metallizing alteration; (3) supergene oxidizing.
