广从断裂飞来岭-象岗山段最新活动性研究
The Latest Activity of Feilailing-Xianggangshan Segment in Guangzhou-Conghua Fault
【摘要】 本文采用野外地质地貌调查、联合钻孔探测、浅层地震勘探、14C测年和ESR测年等技术方法,对广从断裂飞来岭-象岗山段最新活动性进行了综合研究。结果表明:广从断裂飞来岭-象岗山段最新一次活动发生在中更新世晚期。晚更新世以来,该段基本上处于比较稳定的状态。
【Abstract】 The tectonic activity of the Feilailing-Xianggangshan segment of Guangzhou-Conghua fault was investigated with the application of geological and geomorphic survey, combined borehole detecting, shallow seismic prospecting, and 14C and ESR dating technique. The results indicate that the latest activity occurred at the late period of middle Pleistocene. Since late Pleistocene, this segment was relatively inactive on the whole.
