【摘要】：源-汇系统研究已成为世界范围内地球科学领域广为关注的重要课题.陆相盆地作为源-汇系统研究的重要方面,相对于洋陆边缘源-汇系统,其源-汇系统要素多样、过程复杂、沉积体系多变,耦合模型预测难度大,且尚处于起步阶段.陆相盆地源-汇系统研究主要集中于驱动机制及地球动力学过程、深时古气候、沉积盆地古物源区演化恢复与古水系重建、源-汇系统要素分析及剥蚀-搬运-沉积过程单因素分析与耦合模式探讨.基于钻井、岩心、分析化验数据的多方法物源示踪分析与三维地震数据的地震地貌学或地震沉积学分析,为地下陆相盆地古源区恢复、古水系重建及沉积体系的沉积地貌和沉积过程研究提供了重要的技术支撑.关注不同母岩区源-汇系统差异,开展现代考察与古代源-汇相结合,并尝试定量化源-汇系统耦合-过程研究,最终形成工业化标准与规范是陆相盆地源-汇研究的发展趋势.
[Abstract]:The study of source-sink system has become an important subject in the field of earth science worldwide. As an important aspect of the study of source-sink system, the continental basin, compared with the oceanic margin source-sink system, has a variety of elements, complex processes, variable sedimentary systems, and the coupling model is difficult to predict, and is still in its infancy. The studies of source-sink system in continental basins are mainly focused on the driving mechanism and geodynamic processes, the deep paleoclimate, the evolution and restoration of the source region of sedimentary basins and the reconstruction of paleodrainage systems. Source-sink system element analysis and denudation-transport-deposition process single-factor analysis and coupling model. Multi-method source tracer analysis based on drilling, core, analysis of test data and seismic geomorphology or seismic sedimentology analysis of three-dimensional seismic data are used to restore the paleo source area of the underground continental basin. The reconstruction of paleodrainage system and the study of sedimentary geomorphology and sedimentary process provide important technical support. Paying attention to the differences of source-sink systems in different parent rock regions, combining modern surveys with ancient source-sink systems, and trying to quantify the coupling and process of source-sink systems, It is the development trend of source-sink research in continental basins to form industrialization standards and codes.
