Examples
- The fault faults from basemet to quaternary system , and has the feature of contemporaneous and normal fault
该断裂自基底一直断到第四系，具同生正断特征。 - The fault zone passes through the offshore between the changdong islands and the dazhudao island , and consists of a group of nw trending faults , which are dominated by normal and reverse slips with strike - slip component
该断裂带由一系列北西走向的次级断层组成，主体在长岛至大竹岛之间的海域，多数断层以正断兼有走滑运动为主，部分断层具有逆冲运动性质。 - The first phase involves the formation of thrusting and napping towards nww accompanied by extensive igneous activity and mineralization . the second phase corresponds to the development of asymmetrical small fold downwards north and south . the final phase the cenozoic is marked by strong brittle fractures activity resulting in the sharp heave of the landform of xiaoqinling aera
太华群内的褶皱及南北两侧断裂分析表明，小秦岭燕山期至少经历3期变形，第一期为sse nww向的褶皱变形作用；第2期为南北向正断下滑剪切作用；第3期为脆性正断作用。 - Because of those , the paper systems analysis the complicated geological environment , the character of rock mass ' s stress field and the stability of landslide on the right bank , in addition , the paper also deeply studied the geological engineering problem after the dam was builded in order to provide science datum for engineering decision , and elicited several conclusion : ( 1 ) the character of rock mass ' s stress - strain and new structure stress fieldrfrom the middle of q3 to today , the direction of the maximal principal stress has already changed to the sn , the stress - strain action and three direction of stress have been changed from " potential positive break " to " potential slide "
同时通过以上的分析研究本文得出了以下主要的结论与认识： ( 1 )最新构造应力场与地壳岩体应力?形变作用的现今特征：自晚更新世( q _ 3 )中期以来，区域应力场的最大主应力( _ 1 )作用方向转为近南北向( n10 w )作用并一直持续至今，地壳岩体的三向应力状态及应力?形变作用经历了由早期的“潜在正断型”转变到近期的“潜在走滑型”两个不同的发展阶段。
