补充资料:滑脱构造
以一个相对低的岩石强度和高剪应变为特征的软弱层为滑脱面,其上盘岩石从下盘滑脱而形成的构造。滑脱面常由不同规模的一条断层或一个断层系(脆性或韧性)组成,一般顺层发育,如地层或岩系分界面、不整合面或地层中岩性显著差异的分隔面等。该面分割了上下不同应变特征和力学性质的岩片。滑移距离很大的上部岩片组成了外来构造岩片。滑脱作用可以发生在盖层各岩系之间、盖层与基底之间,上、下地壳之间、地壳与上地幔之间以及岩石圈与软流圈之间。岩石圈中多级分层及滑脱构造的发现是构造地质学认识上的重大突破。
根据变形过程中的应力状态可将滑脱构造分为两类:①伸展型滑脱构造,即拆离构造,是指在伸展(拉伸)作用下沿层间近水平或低角度的正断层滑移的构造。它将块体划分为上拆离盘和下拆离盘。上拆离盘是由叠瓦状铲式(上陡下缓)正断层系或多米诺正断层系组成的脆性变形域;下拆离盘往往由糜棱岩带组成、具面理及线理构造的塑性变形域(见图)。②压缩型滑脱构造,在挤压作用下沿层间近水平或低角度的冲断层而滑移的构造。欧洲侏罗山式褶皱及加拿大落基山前陆的冲断褶皱带都是沉积盖层沿基底表面滑脱所成的典型构造。底部的滑脱带在地壳深部表现为韧性滑脱剪切带及糜棱岩带,有时伴随中、高压变质带。压缩型滑脱构造的上部岩片发育一系列叠瓦状的铲式冲断层,自上而下褶皱轴面及劈理面常表现为由陡立、倾斜向水平呈递进演变的规律。
