中国盆地动力学研究现状及展望

Research Reviews and Prospects of Sedimentary Basin Geodynamics in China

沉积盆地既是人类最重要的资源宝库,又包含了丰富的全球气候变化、流体流动和地球动力学等相关信息。人类社会对矿产资源和水资源的大量需求推动盆地分析领域的快速发展,地球科学家对沉积盆地开展了多年的系统性探索,在盆地形成和演化机制、沉积充填、盆地流体及相关资源的聚集过程等诸多方面的研究取得了一系列重要的进展和突破,形成了一门新兴的学科—盆地动力学。近年来,我国学者在大型叠合盆地和大陆边缘盆地的动力学过程、陆相盆地层序地层、深水沉积、源—汇系统等方向取得了显著成绩和突出进展。相关成果不仅有效地服务于能源、矿产、水资源等各类资源勘探,而且为地球动力学、重大构造事件、全球环境变迁及气候演变研究提供了丰富资料和详实证据。

Sedimentary basin,a huge and important treasury of resources,comprises significant information of global climate change,fluid flow,geodynamics,and so forth.The requirements of mineral products and water resources for economic construction have speeded the development of sedimentary basin analysis.With years of systematic exploration towards sedimentary basin,a series of significant progresses and breakthroughs have been achieved in various aspects,which involve the formation and evolution mechanism of sedimentary basin,basin fillings,basin fluids,accumulation of the related resources,and so on.Subsequently,a new discipline termed as sedimentary basin geodynamics come into being.For the past few years,Chinese scholars have made outstanding achievements and progresses in many aspects,such as the dynamics processes of large superimposed basins and continental margin basins,continental sequence stratigraphy,deep-water sedimentation,and source-to-sink system,and so on.These researches not only serve various resource explorations comprising energy sources,mineral products,water resources,but also provide abundant information and detailed evidence for the researches on earth geodynamics,significant tectonic events,and global climate and environment changes.
