摘　　要：本文通过对泰前断裂显微构造,石英组构特征进行研究,认为该断裂是一条自中生代形成以来经历了四次不同力学性质的活动断裂:断裂受到NE-SE向主压应力作用,发生了右旋压扭活动;断裂受到近东西向的主压应力作用,发生了右旋张扭活动;断裂受到NNW-近南北向的主压应力作用,发生了左旋压扭活动;断裂受到NE-SW向的主压应力作用,发生了左旋张扭活动。ABSTRACT The microstructures and fabrics of quartz in the fault zone in the fore of Taishan Mountain have been studied. From this study,it is sug- gested that the fault is an active fault of the repeated activities. The move- ments along the fault started from Mesozoie and have been continuing activi- ties for four times. Since the fault had been compressed by the stress near NW-SE direction, the compression-torsion movement along the fault took pl- ace with clockwise torsion developed; Since the fault had been compressed by the stress near east--west direction, the stretching-torsion movement along the fault took place with clockwise torsion developed; Since the fault had been compressed by the stress near NS--NNW direction, the compression-to- rsion movement along the fault took place with counterciockwise torsion de- veloped; Since the fault has been compressed by the stress near NE--SW di- rection,the stretching-torsion movement along the fault has taken place with counterclockwise torsion develooed.
