    断裂、褶皱

    Fault and Fold

    断层是岩层受力后发生破裂,断裂面两侧的岩(地)层产生位移。褶皱是岩层受力后发生的弯曲现象。本处断层是逆断层,上盘(西侧)上升,下盘(东侧)下降;上盘岩层发生弯曲,形成了N型同斜褶皱。

    A fault is a geological structure in which rocks strata were fractured under stress, with the obvious displacement happening along the fractured plane. A fold is a geological structure which the strata were bent after stress. Here, the fault is a thrust fault with an up-block uplifted and a lower-block moved down. The fold, consisting of syclines and anticlines here, was produced during fault movement.
