Numerical ocean model investigations of north-south epicontinental seaways : unraveling the jurassic thermohaline circulation ?

南北陆表海通道的大洋数值模型研究：侏罗纪温盐环流的解释

In early permian period , the epicontinental sea of north china platform receded conti-nously to the south , thus the-coal accumulations of continental delta facies are generated inthe southeast of north china platform .

二叠纪早期，华北地台的陆表海不断向南退缩，从而在华北地台东南部开始了陆相三角洲的聚煤作用。
