摘要
前陆盆地发育于前陆褶皱冲断带之上。它是在褶皱冲断带负载的作用下,岩石圈通过区域性均衡调整及流变挠曲而形成的。本文从流变学角度讨论了在前陆地区褶皱逆冲作用下,岩石圈流变、盆地形成及沉积充填三者间的内在成因联系,并着重介绍了前陆盆地形成过程中的两种岩石圈流变挠曲模型及前陆盆地充填演化的模拟反演。
Foreland basins developed between fold-thrust belts and cratons which had been overthrusted by thrust faults. They were formed through regional isostatic adjustment and Theological flexure under the load of fold-thrust belts. This article discussed the internal relationship among lithospherical rheology, basin's forming and sedimentary filling under thrusting in the foreland area, and introduced two models of lithospherical rheological flexure during the development of foreland basins and the simulation of foreland basin-filing evolution.
