鲁北地区和鲁西南地区古近纪盆地在地层、沉积和构造演化上都具有可对比性。鲁西南露头区古近纪地层及其沉积特征的研究对鲁北覆盖区古近纪古环境的恢复和沉积特征研究起到重要的参考作用。本文对两个地区的地层和沉积特征进行了对比。根据官庄群在鲁西南地区的沉积分布,发现了在晚白垩世至早始新世鲁西南盆地发生时间有从南向北、由东向西推迟的规律。通过对鲁西南和济阳坳陷沉积和断层发育特征的对比研究发现,郯庐断裂在晚侏罗世至早始新世以左旋剪切活动为主,派生了鲁西南和济阳坳陷NW向的断层;早始新世末期是一个构造转型期,鲁西南和济阳坳陷发育了近EW向的断层;中、晚始新世是郯庐断裂右旋剪切活动最强烈的时期,鲁西南和济阳坳陷发育了NE向断层。
The Paleogene basins in the Lubei area and the southwestern Shandong area are comparable in terms of stratigraphy, sedimentation and tectonic evolution. The study of Paleogene strata and their sedimentary characteristics in the outcrop of Luxinnan plays an important reference role in the research on the restoration and depositional features of Paleogene paleoenvironment in Lubei area. This article compares the stratigraphic and sedimentary features of the two regions. According to the sedimentary distribution of the Guanzhuang Group in the southwestern Shandong region, it was found that the occurrence time of the southwestern and eastern-western regions from the Late Cretaceous to the Early Eocene was found to be delayed. By comparing the sedimentary and fault features of the southwestern Shandong and Jiyang Depression, it is found that the Late Lunar-to-Early Pliocene faulting in the Tancheng-Lujiang fault mainly dominated the left- The late Early Pleistocene is a tectonic transitional period, and near EW trending faults are formed in the southwestern Shandong and Jiyang Depression. The middle and late Eocene are the most intense periods of right-lateral shearing of the Tan-Lu fault, NE-trending faults develop in the southwestern Shandong and Jiyang depressions.
