| Abstract: | Xiaoshan-Yanshan alunite deposit is a large type one. Its host rock, Shangxiwu group,is calci -alkali volcanic series, and consisted mainly of middle-acidic pyroclastics, and which formed in Proterozoic volcanic arc evironment. The Yanshan deposit area underwent volcanic eruptive-sedimentation, volcanic hydrothermalsolution and tectonics, It was formed as a complex and multi-origin superimposed. The origin of Yanshan alunite deposit was volcanic eruptive sedimentation - hydrothermal replacement; the minerogenetic epoch was volcanic eruptive-sedimentary period of Yanshan formation of Proterozoic Shangxiwu grou. The gold ore body was strictly controlled by failts, and its main minerogenetic epocj was fanlt active period of Yanshan deposit area. According to the new thought obtained from minerogenetic characteristics of Yanshan alunite deposit, we discovered Shangxiwu reservior and West -Dayanshan alunite mineralizing zones. Furthermore, the minerogenetic geological setting is good and there is a prospective to discover a certain scale alunite deposit |
