通过对下辽河地区古地磁样品分析。发现缺失松山反向时的磁性地层,即没有早更新世的沉积地层,讨论了此现象和郯庐大断裂的应力场的变化关系。古地磁分析对本区第四纪磁性地层的划分提供了依据。
Analysis of paleomagnetic samples in the Lower Liaohe River. It is found that there is no early Pleistocene sedimentary strata in the absence of the Songshan reverse magnetic stratum, and the relationship between this phenomenon and the stress field of the Tanlu Fault is discussed. Paleomagnetism analysis provides the basis for the division of the Quaternary magnetic strata in this area.
