碳酸盐与陆源碎屑混合沉积体系研究进展

RESEARCH ADVANCES IN THE MIXED SILICICLASTIC-CARBONATE SEDIMENTARY SYSTEMS

广义的碳酸盐与陆源碎屑的混合沉积是指碳酸盐岩与陆源碎屑岩高频率交互沉积及岩石中碳酸盐组分与陆源碎屑组分的混合产出。本文综述了混合沉积体系的研究意义；评述了８０年代以来的国内外研究现状和成果，认为海平面变化是混合沉积的主要控制因素，其次有构造升降、物源供应、气候以及突发性事件等因素；提出了混合沉积体系的研究应该以沉积相、微相分析为基础，并与沉积地球化学、阴极发光研究相结合。

Mixed siliciclastic-carbonate sedimentation is interbeds of siliciclastic and carbonate rock with high-frequency or Mixed rock with both siliciclastic and carbonate components.This paper discussed research significance of mixed siliciclastic-carbonate sedimentary sys-tems,reviewed present reseach situations and achievements since 1980s, proved that sea level changes are main controlling factors in mixed siliciclastic-carbonate sedimentation,other controlling factors are tectonics,climates,provenances and geological events,and suggested that the study of the mixed siliciclastic-carbonate sedimentary systems should be hased on sedimentary facies and microfacies analysis,sedimentary geochemistry and cathodoluminescence study.
