盆山耦合与沉积盆地成因

我国的沉积盆地成因研究主要遵循盆山耦合的研究思路进行 ,关注重点为盆山体系的构造、沉积和深部结构上的耦合现象。构造耦合研究是指盆山结合带的统一变形特征 ,沉积耦合研究是通过沉积响应去重塑盆山耦合过程及相邻造山带的演化过程 ,深部结构耦合的重点是研究盆山体系在岩石圈尺度的动力学统一性。国际上相应领域的研究重点为岩石圈深部过程与近地表构造过程的耦合。国内外研究既有相同之处 ,又有差异之处。建议在未来的沉积盆地成因研究中更加开阔思路 ,采用天然实验室的工作模式 ,进行多学科综合研究。

Basin-Orogen Coupling and Origin of Sedimentary Basins

The study on origin of sedimentary basins in China followed approach of basin-orogen (range) coupling, including the structural and sedimentary coupling, as well as coupling in deep structure. The structural coupling can be revealed with deformation in the place at which basin and orogen (range) are jointed. The sedimentary coupling implies the tectonic-sedimentary responses that could reconstruct the orogenic process. The coupling in deep structure focuses on lithosphere dynamics revealed by deep structures. Parallel to this, international study on origin of sedimentary basins concentrated on coupling of lithosphere and near-surface processes. Keeping open eyes, integrating different approaches, and co-working in natural laboratories are all important in the future research on sedimentary basins.
