摘要
西倾山地区是近年来新发现的岩溶—热泉式金矿成矿带,其形成是在未形成“硅帽”的情况下由突发涌入(出)的硅质热液沉淀结晶形成的。西倾山弧形构造机制所导致的次级构造(裂隙)以及沿其裂隙侵入的中酸性岩脉或沿裂隙发育的古岩溶构造是主要的容矿控矿构造。在剖面上由上向下具有热泉型—岩溶型—交代蚀变岩型“三层”式的成矿规律。西倾山及李卡如山弧形构造带具有进一步找矿的良好前景。
Xiqingshan region is a newly discoved metallogenic zone for karst hot spring type of gold deposit, which was formed by the pricipitation and crystalization of suddenly emerged siliceous hydrothermal before the formation of ' silicon cap' .The secondery tectonics (fissures), caused by arcuate tectonics mechanism of Xiqingshan, and the intermediate acid dike or paleokarst tectonics developing in fissures are the main host structure and ore-control tectonics. On the section,from top to bottom,it presented a 'three beds'type of metallogenic regularity, that is hot spring type ?karst type ?metasomatic alteration rock type. Xiqingshan and Likarushan arcuate tectonics zone possess better future for furtherprospecting.
