| 摘 要： | 枣子沟金矿位于新堡—力士山复背斜南翼之合作—岷县区域断裂带南侧,是西秦岭西段近些年发现并勘查的大型金矿床之一。其围岩蚀变发育,类型多样。发育有区域地层变质期的面型热液蚀变作用和构造热作用的线型热液蚀变作用两类主要蚀变,其中线型蚀变中的硅化、黄铁矿化、毒砂化及辉锑矿化等蚀变与金矿化关系密切,可作为夏河—合作金矿富集区找矿...

| Abstract: | Zaozigou gold mine is situated the south side of Hezuo-Minxian Fault zone which is the south limb of Xinbao-Lishishan anticlinorium.It is a large scale gold deposit discovered in the west section west Qinling in rescent years.Among the various type of wallrock alteration,the most important types are these two： planar hydrothermal alteration occurred during regional metamorphic period,and linear hydrothermal alteration caused by structural heat activities.Silicification,pytization,arsenpyritization and animonitization of linear alteration were close to gold mineralization. |
