| 摘 要： | 作者将本区的构造演化划分成三个阶段，即海西－印支期、燕山期和四川期。海西－印支期应力作用以近ＳＮ向挤压为主，成矿作用为Ｐｂ－Ｚｎ－Ｃｕ多金属硫化物矿床；燕山期应力作用以ＮＷ－ＳＥ向挤压为主，成矿作用为Ｐｂ－Ｚｎ－Ａｇ为主，平均差应力值１２０．５ＭＰａ；四川期应力作用呈ＮＮＥ－ＳＳＷ向，成矿作用以Ａｇ－Ａｕ为主，平均差应力值１０１．４ＭＰａ。

| Abstract: | Tectonic evolution of southern Daheishan Horst is divided into three tectonic stages, i. e.Hercynian- Indosinian stage,Yanshanian stage and the Sichunian stage. In Hereynian-In-dosinian stage,a series of folds with EN trending axis were formed by north-southward compressioil.It belongs to Pb-Zn-Cu sulphide deposit on metallegenesis. Themaxilnum principal axis of compressive stages in Yanshanian stage is NW SE trending,withmainly Pb-Zn-Au-Ag metallogenesis. The average value of differential stress is 120. 5 Mpa.The stress axis in Sichuanian stage is NNE SSW trending.The average value of differentialstress in the Yanshai1ian stage is 101. 4Mpa. The metallogenesis in Sichuanian stage is domi-nated by Ag-Au deposits. |
