| 摘 要： | 在计算覆盖整个黄晔裂谷２００口人工井（包括少部分探井）沉降量的基础上，总结本区二种基本沉降曲线模式。统计出热沉降（Ｓｔ）与初始沉降（Ｓｉ）之比为０．６，依此为约束条件与大陆岩石圈伸展的地球动力学正演模式进行对比，与简单剪切模式预测的热沉降与初始沉降之比值及几何效应更接近。进一步证实黄骅裂谷以简单剪切机制形成的地球动力学模式更合理，这与著名的以纯剪模式形成的北海伸展盆地不同

| Abstract: | On the basis of subsidence data calculated on over two-hundred artificial wells in the Huanghua rift , the authors of this paper got two kinds of subsidence curves. The ratio of the thermal subsidence to the initial subsidence is also calcuiated. In comparison with the previous geo - dynamical models of the continental lithosphere extension , ours is more similar to the simple shear model. So it is proved that the rifting in Huanghua basin accommodated under the simple shear pattern, which is different from the North Sea extensional basin formed by pure-shear model. |
