摘要
通过搜集资料和野外地质调查,对胶南块体周边及内部主要断裂的最新活动进行了判定,结合研究区的地震活动情况进行分析,得出了该区构造活动较弱、与地震活动情况较为一致的结论,据前人研究,胶南块体隶属于苏鲁造山带,其周边断裂都具有一定的新活动迹象,而内部断裂活动性弱,证明胶南块体内部相对稳定。
Through data collection and field geological survey on major faults of the Jiaonan terrane ,the latest activity of the faults is determined ;combined with seismic activity in the study area it can be proved that the Jiaonan terrane is a weak tectonic activity area ,and the result is consistent with the seismic activi‐ty conclusions .According to previous studies ,Jiaonan terrane is part of the Sulu orogenic belt and its sur‐rounding faults have some new signs of activity ,w hile the internal faults activity is less than the surround‐ing faults .T hese evidences prove that the Jiaonan terrane is relatively stable .
