| 摘 要： | 通过对胶州湾湾口海区磁力异常进行的定性和定量解释,并结合其它地质地球物理资料的综合分析认为,测区内存在1条NW向断裂、2条WNW向断裂及3条NE向断裂。其中NW向断裂(F3断裂)是1条新发现的断裂,属右旋断裂构造,并被多种中基性岩脉所填充。根据区内断裂构造的组合交切关系推定,F3断裂比沧口断裂活动时代要早,为非全新世活动断层。

| Abstract: | It is shown from the interpretation results of magnetic anomalies and the analysis results of other geologic and geophysical data in the Jiaozhou Bay mouth sea area that there are a NW trending fault,2 NWW trending faults and 3 NE trending faults in the survey area.Among them,a NW trending fault F3 is a new found fault with a right-lateral fault structure,and was filled by several kinds of medium-basic dikes.It is concluded from the combination and intersection relations of fault structures in the area that the active age of fault F3 is earlier than that of the Cangkou Fault,and the fault F3 is not a Holocene active fault. |
