地震韵律研究方法初探--以郯庐断裂带龙泉山西麓剖面研究为例

通过对郯庐断裂带龙泉山西麓剖面的精细观测，样品微观和超微观测试，断层物质活动时代测定和综合分析研究，发现断裂带在第四纪曾有过多次活动（其中晚更新世以来也曾有过活动），并呈现粘蠕滑交替的变形特征，其最新活动方式以蠕滑活动为主，这些结论修正了前人对郯庐断裂带南段的基本认识，丰富和深化了该断裂新活动的研究内容。

Preliminary Research Method of Seismic Rhythms--Taking the Research on the Longquanshan West-foot Profile in the Tancheng-Lujiang Fault Zone as An Example

By means of fine field observation, Microscopic-untromicroscopic testing of the samples, dating of fault materials and synthetic analysis for the Longquanshan west-foot Profile in the Tancheng-Lujiang fault zone, we found there were many times of activities in the fault zone in Quaternary(including Late-Pleistocene), which presents the deformation characteristics that the sticky and creep slipping alter activity. The latest activity takes sticky slipping as the main. These results have corrected the basic understanding of previous researchers to the south segment of Tancheng-Lujiang fault, richened and deepened the researching content of new activity in this fault segment.
