苏北盐阜地区中、古生界地层分布特征
|
摘要
应用钻井、测井及古生物资料,对下扬子苏北盐阜地区中、古生界地层进行研究,同时综合了重、磁、电、二维地震、MT二维剖面等资料,探讨盐阜地区中生界残留地层展布规律。研究结果表明,中生界白垩系浦口组在研究区广泛分布,厚度较大,且分布稳定,而赤山组、葛村组及侏罗系、三叠系局部零星分布;上古生界地层残存在滨海隆起—建湖隆起引水沟凸起一带,下古生界地层残存在淮阴凹陷—盐城凹陷地区。
The Mesozoic and Palaeozoic strata in the Lower Yangtze Region, particularly in the Yanfu area of northern Jiangsu have been studied using drill hole, well log and paleontological data, as well as gravity, magnetic, electrical, 2-D seismic, and 2-D MT data. Spatial distribution of the Mesozoic and Palaeozoic strata is described. The Late Cretaceous Pukou Formation is very thick and distributed widely. But the Chishan Formation, the Gecun Formation, and the Triassic-Jurassic strata have a sporadic spatial distribution. Upper Paleozoic strata are distributed mainly in a zone from the Binghai uplift to the Jianhu uplift to the Yinshuigou uplift, and Lower Palaeozoic strata are distributed mainly in a zone from the Huaiyin sag to the Yancheng sag.
