| 摘 要： | 本文通过山门银矿区小型构造的研究，将本区中，新生代构造应力场划分为三期，即侏罗纪，白垩纪，老第三纪构造应力场。最大主压应力方向分别为ＮＷ－ＳＥ向，ＮＮＥ－ＳＳＷ向和ＥＷ向。估算出侏罗纪差应力值１０６．１ＭＰａ，白垩纪差应力值１０．１７Ｍｐａ利用白垩纪构造应力场数学模拟成果，结合物，化探资料，划分出三个成矿远景区。

| Abstract: | In this paper,the Mesozoic Cenozoic tectonic stress fields of Shanmen silver mining area are divided into three tectonic stages, i e the Jurassic stage,Cretaceous stage and Tertiary stage The maximum principal axis of compressive stress in Jurassic trends NW SE,in Cretaceous it is NNE SSW,and that in Tertiary is EW The average value of differential stress in the Jurassic stage in 106 1 Mpa,and that in Cretaceous is 101 7 Mpa On the basis of tectonic stress field mathematical simulation integrated with geophysical and geo chemistry data,three minerogenetic provinces are regionalized |

| Keywords: | Mesozoic and Cenozoic era Principal direction of stress axes value of differential stress Shanmen silver ore deposit |
