摘要:

文中利用遥感影像分析了徐州废黄河断裂带的空间展布及与邵楼断裂的交切关系,利用重磁资料研究了废黄河断裂带的深部几何结构及与郯庐断裂带西边界的交切关系。二阶布格重力异常小波变换细节图反映出徐州废黄河断裂带的深度为7~8km,而三阶和四阶重力异常细节图反映的深度分别为9~11km和15~18km。研究结果表明,废黄河断裂带向SE延伸至九顶附近,向下的切割深度约为 8~9km。NW向的废黄河断裂带截切邵楼断裂致使邵楼断裂构造线自东北向西南由N60°E转至N45°E。废黄河断裂带与郯庐断裂带不相交。废黄河断裂带属于前第四纪断裂,活动性较弱。

Abstract:

Based on the remote sensing images interpretation,the spatial distribution of the Fei Huanghe(the ancient Yellow River)fault zone in Xuzhou area was studied and the intersection relationships between Fei Huanghe Fault and Shaolou Fault,and Tan-lu Fault were discussed in the paper.Besides,we researched the deep-seated geometric structure of Fei Huanghe Fault by studying the gravity-magnetic data,and discussed the intersection relationships with the west boundary of Tan-lu Fault. The cutting depth of Fei Huanghe Fault reflected by second order-wavelet transform detail of the Bouguer gravity anomalies is up to 7~8km.The depth reflected by the third order-wavelet and fourth order-wavelet transform detail of the Bouguer gravity anomalies is up to 9~11km and 15~18km,respectively.The results show that the Fei Huanghe Fault extends to Jiuding in southeast direction.The cutting depth is up to 8~9km.The NW-trending Fei Huanghe Fault cut the NE-trending Shaolou Fault,resulting in the change of the tectonic line of the latter from striking N 60°E to N 45°E.Moreover,the Fei Huanghe Fault didn't cut the Tanlu Fault.It is a pre-Quaternary Fault with weak activity.

Key words: Fei Huanghe Fault zone, remote sensing, gravity and magnetic anomaly, historical earthquake, Xuzhou
