Abstract:

温泉盆地西缘断裂在晚第四纪期间经历了多期活动。沿断层至少可以识别出高度分别为0.33~0.62m、4.3~5.2m、6.8~8.3m、10~11.8m、约16m、20-28m、45-50m和65-80m的8套断层崖或断层陡坎,以及与各级断层崖大致对应的河流阶地、洪积扇和泉华台地。地质地貌体的相对时代分析和泉华、河流沉积物中的砾石钙膜、钙质胶结物的U系、ESR测年结果表明,高45~50m、20-28m、约16m、10~11.8m、6.8~8.3m和4.3~5.2m的断层崖可能分别形成于约127kaBP、54kaBP、25kaBP、18kaBP、11kaBP和4kaBP以来或更早。综合分析断裂不同地点的断层崖的高度和时代发现,不同时期的断裂活动强度可能是不同的。其中在约127-25kaBP、25~4kaBP期间,断裂平均的垂直活动速率分别为0.3-0.23mm/a、0.8-0.36mm/a,而约4~1.1kaBP期间的断层最大垂直活动速率可能达1.65mm/a。
