盆地沉积动力学：研究现状与未来发展趋势

盆地沉积动力学或称盆地沉积充填动力学分析,即强调盆地沉积特征与形成过程的响应关系及控制机制的研究,是沉积盆地分析和油气地质研究的一个前缘领域。文中结合中国沉积盆地的特色和研究实践,阐述了这一领域的研究现状,展望了未来的发展趋势。当前盆地沉积充填动力学分析的主要热点方向包括：①盆地的沉积层序结构、沉积体系（域）构成和演化及其响应机制研究;②盆地构造沉积学或构造地层学分析;③源-汇系统与盆地沉积物分散体系研究;④盆地沉积充填动力学过程的模拟分析等。盆地沉积充填动力学分析将不断为地球动力学系统研究提供高分辨的沉积记录,并继续为难度日益增大的沉积地质资源的勘探和开发提供新的理论支撑。盆地沉积动力学研究预示了深远和广泛的发展前景。

Sedimentary dynamics of basin: Status and trend

Sedimentary dynamics of basin or sediment filling dynamics of basin, a frontier in sedimentary basin analysis and petroleum geologic research, highlights the response relationship between basin filling characteristics and formation processes, as well as its controlling mechanisms.The status and trend of the study were documented considering the geographical features and research practices of sedimentary basins in China.The main themes include:① sequence architecture of sedimentary basins, as well as structure, evolution and process responses of depositional system tracts;② tectono-sedimentology or tectono-stratigraphy;③ "Source-to-Sink" system and sediment dispersal systems in basins;④ simulation of basin filling processes and so on.Analysis of sedimentary basin filling dynamics will continue to provide high-resolution sedimentary records for geodynamics, and theoretical support for the exploration and development of depositional geological resources, which have become increasingly difficult.The study betokens profound and new prospects.
