摘　　要：静北潜山的油气勘探始于上世纪70年代初,并将钻井揭示的未见化石的碳酸盐岩和石英砂岩沉积划归中元古界长城系,沿用至今。2002年在对该区的地层研究中,首次发现了晚古生代孢粉化石,从而证实静北潜山存在晚古生代地层。本文以孢粉化石为主要依据,对潜山地层进行了重新划分,并与邻区进行对比。在此基础上对本区的构造和沉积作一讨论。Petroleum exploration in the Jingbei buried hills began in the early 1970＇s, and drilling data revealed that carbonatite and quartz sandstones contain no fossil and can be classified to the Changcheng Period, Mesoprotozoic, which is still in use nowadays. Sporopollen fossils were first found in the stratum of this area in 2002, which proved the existence of Late Paleozoic stratum. Based on sporopollen fossils, the paper reclassified the stratum in the buried hills and compared it with adjacent area, and further discussed the structure and sediment.
