| 中文摘要: |
| 本文依据江苏如东滩涂区综合地球物理调查工作，对小洋口地区断裂构造空间展布进行了解译，分析了解译断裂与栟茶河断裂的关系。解译结果主要参考实测无人机航磁资料，辅以浅层地震和电磁法资料。综合两个子测区的断裂构造解译结果，同时参考华东地区航磁和重力资料，对栟茶河断裂的空间展布位置进行了推断，认为其是近EW向大型断裂，延伸距离长，同时控制测区其他断裂的展布。实测数据未发现金坛—如皋断裂在测区范围内存在的地球物理证据，分析认为其未发育至栟茶河断裂以北。 |
| 英文摘要: |
| Based comprehensive geophysical surveys in the mudflat area, Rudong County, Jiangsu Province, this work inferred the extension of faults in the Xiaoyangkou area, especially the Benchahe fault. The structural interpretation relied on measured UAV-borne magnetic data in combination with shallow seismic and electromagnetic data. Integrating interpretation results of the two sub-areas, with reference to aeromagnetic and gravity data in East China permitted to infer the spatial extension of the Benchahe fault. Research suggested that this fault is a large-scale nearly EW trending feature with a long extension distance and controls the distribution of other faults in the survey area. No geophysical evidence was found for the existence of the Jintan-Rugao fault from the measured data and it was considered that this fault doesn’t extend to the north of the Benchahe fault. |
