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.
Source-to-Sink（S2 S）system has attracted a wide attention,and currently becomes the important issues covered in earth science field.As important composing of S2 S,the continental basin,unlike marine continental margin basin,consist of multiple units or elements,complex sediment process,various sedimentary system,and unpredictable coupling model in the source to sink system.However,at present such domestic concern of S2 Sin the continental basin is still at an early stage.The S2 Ssystem in the continental basins consist essentially of sediment supply,transport and depositional dynamic processes and mechanisms,deep-time paleoclimate and S2 Sanalysis,the morphological and sedimentological aspect of erosional-depositional systems,elemental analysis and coupling model investigation of S2 Ssystem.Multiple methods in sediment tracing based on borehole,core and other test data to reveal paleo-provenance and reconstruct paleo-drainage in the continental basin.Then,seis-mic geomorphology or sedimentology based on high resolution 3 Dseismic data provides a tool for study of subsurface depositional geomorphology and processes.Focus on S2 Srelationships for various source-rock combinations,new method for S2 S study by integrating modern system and subsurface interpretation,establishment of quantitative relationship from source to sink,and form industrial application standard are the research trends of S2 Ssystem in the continental basins.
