海州湾地区新构造运动及其水系变化

一、海州湾地区新构造 运动特征 本区系沂沭断裂带与黄海断陷所夹持的楔形断块,南隔响水断裂带,濒临下杨子断块,北接山东文登—日照断隆与胶东断块构成一体。其间又有芎海隆起作东西穿过。 盱眙—响水深断裂,在海州湾南侧经灌南县田楼至燕尾港灌河口作北东向延伸,将海州湾沿岸及其邻近地区分成截然不同的两部分,

THE NEOTECTONIC MOVEMENT AND THE CHANGE OF WATER SYSTEM IN THE REGION OF HAIZHOU BAY

Our study indicates that the rifts of Xiangshui, Yishu and Jiaonan edged the region of Haizhou Bay with distinct boundary. This region, with the second-class rifts lying northeast and northwest, shows its structure of fault block clearly. Because of the obvious neotectonic movement and its variation in this region, the relief was higher in the northwest and lower in the southeast, with the Mount Yuntai being raised as a fault block, hence the coast and surface water system were changed.
