准噶尔盆地南缘断裂带显微构造特征与活动时代 - Field investigation reveals that the latest time when yumen fault , western part o f qilian mountains was active is the end of the late pleistocene , and that the fa ult is coincident with other faults around west jiuquan basin . it is also found t hat yumen fault had not simply restricted to dip - slip motion ， strike - slip moti on is indicated . the results suggest that west jiuquan basin block might have rot ated clockwise
新的证据显示，位于祁连山西段酒西盆地南部的玉门断裂的最新活动时代为晚更新世末，并兼有一定的走滑分量这一结果表明，酒西盆地块体周边断裂的活动具有同时性的特点，酒西盆地块体可能发生过顺时针旋转 - Base on the definition of active fault and its meaning to engineers , this paper reviews some geological aspects and problems , such as the application of dating results in determination of active faulting ages , seismo - tectonics background studying on moderate - strong earthquakes , estimating earthquake recurrence from geological investigation , and probabilistic evaluation of the ground offset of active fault
摘要本文在对活动断层的工程涵义进行了简要分析后，讨论了断层物质测年的工程应用进展及其断层活动时代鉴定问题，并就如何加强中强地震发震构造判别、应用地震地质资料评估大地震年平均发生率、以及活动断层地表断错位移的概率评价等问题作了初步探讨。
