    • Abstract
  • In this paper, macroscopic characteristics, ore material composition and structural features, wall rock alteration, geochemistry of Chen'er gold deposition of the Xiaoqinling gold field was analyzed.Combining with previous researches on diagenesis and mineralization chronology, it is indicated that this region has mainly experienced two metallogenic and superimposed mineralization stages:early Indosinian when altered mylonite-type gold deposit was formed, whose mineralization effects was related to ductile shear, and late Yanshanian, when the quartz vein type gold depositwas formed, whose mineralization was related to magmatic hydrothermal process.The ore type, ore texture and structure, ore controlling tectonic direction properties, wall rock alteration, fluid inclusion characteristics formed in the two stages of mineralization are quite different, with a certain degree of superposition in space but not completely overlap. Superimposed mineralization further enriches the ore bodies.It is indicated that Chener gold deposit has superimposed and reformed mineralization characteristics. East-west and south-north intersectionsare favorable target areas for gold deposit prospecting.
