郯城-庐江断裂带纵贯我国东部,北起黑龙江省,南至安徽省并继续向南延伸,在我国境内长达三千余公里。本文主要讨论渤海海域中的一段,即北起辽宁营口,南至山东潍坊,长约五百公里。为了讨论的方便,我们将其称为营潍断裂带。该带完全被海水或第四纪地层复盖。对它的了解过去只是根据周边地质情况予以推断,自航磁工作开展以来,对此问题的认识有所深入,认为该断裂带自山东向北延入莱州湾属于深断裂性质,继续北延,虽仍为大断裂存在但由于无岩浆活动,而被认为属“干断裂”性质。随着海洋石油勘探事业的发展,近十几年来在渤海海域进行了重力、磁力、地震综合物探普查
Tancheng - Lujiang fault zone runs through the eastern part of our country, north of Heilongjiang Province, Anhui Province to the south and continue to extend to the south, up to 3,000 kilometers in our territory. This article mainly discusses a section of the Bohai Sea, namely Yingkou in Liaoning Province in the north and Weifang in Shandong Province in the south, about 500 kilometers in length. For the convenience of discussion, we call it Camp Ying fracture zone. The belt is completely covered by seawater or Quaternary formations. Its understanding of the past is only based on the surrounding geological conditions to be inferred, since the commencement of aeromagnetic work, the understanding of this issue has been further deepened, that the fault extending from north to laizhou Bay in Shandong belong to the deep-fracture nature of the North, Although still a major fault, it is considered a “dry fracture” due to no magmatic activity. With the development of offshore oil exploration, geophysical surveys of gravity, magnetism and earthquake have been carried out in the Bohai Sea area in recent decades
