南沙海区海洋沉积学研究进展

A DVANCEMENT OF MARINE SEDIMENTOLOGY IN NANSHA SEA AREA

简要介绍了中国科学院南沙综合考察队有关海洋沉积学十年科考取得的研究进展，包括现代沉积作用过程、沉积地球化学、礁碳酸盐地质学、盆地分析、古海洋学与全球变化等方面。

Advancement of marine sedimentology in Nansha sea area, which include aspects ofmodern sedimentation,sedimentary chemistry,stratigraphy,reef carbonate geology,pa-leocenography and global change,are indicated and comented.The research of modermsedimentation involved shelf deposite,coral growth, biogenic and gravity flow sedimenta-tion.The following reports the development of element and isotope geochemistry of sedi-ments,late quaternary stratigraphic sequences and reef carbonate faces and model.Thelast part of this paper introduces general development of late quaternary paleoceanographyand global change.These results promote the understand of rnonsoon climate.
