近廿多年来,随着人类对油气资源和其它矿产需求的增加和对人类生活环境的保护,以及边缘学科与新技术的兴起,使沉积学的研究领域更为扩大和深入。它已从人类熟知的大陆扩展到两极和荒漠的研究;从陆地和大陆边缘海域扩展到深海的研究;从区域地质调查扩展到全球的研究;从寒武纪以后的地层扩展到前寒武系的研究;从地壳浅部扩展到地球深部地幔地核以至宇宙其它星球的研究等等,这些都标志着地质科学发展的新阶段。

This paper is a part of the "Opening Speech" of the Second National Sumposium on Sedimentary Facies of Clastic Rocks held in Daqing City in sept. 1985. It introduces and studies the recent developing trends of sedimento-logy at home and abroad.Moreover, it proposes a new way for the national researches on sedimentology in the future. In these years, the sedimentology emphasizes the integrated analyses on the indicators of multiple facies and opens up a new frontier for the development of production. Meanwhile, it attaches a great importance to modern sedimentation, event deposition and modelling experiments of flume, seeking for a new depositional mechanism and its model. The oil/gas and saline deposits in China are closely related to the depositional environment of non-marine, lacustrine facies. Therefore, it is a great significance for the national sedimentologist to establish and develop the lacustrine sedimento-logy.
