沉积盆地动力学研究新进展

Progresses on the research of geodynamics in sedimentary basins

盆地动力学是一门通过研究发生在地球深部(包括地壳和岩石圈以下)的物质、能量交换和平衡过程,来揭示盆地的成因、演化机制、成矿过程及其全部动力学过程的科学。作为当代地学的前沿课题之一,在近10 a之内取得了一系列研究进展。在大量文献调研的基础上,分别从深部作用、热动力、动力学模拟、盆山耦合、盆地充填动力学、流体成矿动力学、成藏动力学及成煤动力学等方面,分析总结了国内外沉积盆地动力学研究现状与研究进展。认为沉积盆地动力学仍是今后地质学研究的前缘和热点,盆地动力学研究趋向于定量化、整体化、动态化和综合化,注重深部信息的获取和深部作用的研究。

Basin geodynamics is to reveal genesis,evolution,mineralization and all dynamic processes in basins by study on material and energy exchanges and balance process in deeper earth(include crust and under lithosphere).A series of progresses on geodynamics has been made in the past ten years.Based on a great amount of literature investigation,the status and progresses on geodynamic research of sedimentary basins both at home and abroad are summarized and analyzed in terms of deep response,thermal dynamics,dynamics simulation,coupling of mountains-basins,sequence-filling dynamics,dynamics of fluid mineralization,dynamics of reservoir formation and dynamics of coal genesis etc.It is proposed that geodynamics of sedimentary basins is still the front and hotspot of geologic study.The study is tending to quantification,macrocosm,dynamics,integration, and attaching importance to acquiring information in deeper formation and research on deep reaction.
