摘要
全球性旋回沉积是全球海平面变化、全球气候条件、全球构造演化、全球古地理背景及沉积特征综合作用的产物。全球旋回地层学是综合应用概念性的、定性的和定量的方法研究地层记录中由气候和构造过程引起的旋回沉积模式的一门学科，它是脱胎于层序地层学的一门新的地层学分支。全球旋回地层学通过估算沉积盆地中沉积物类型和沉积环境变化来预测地层学特征，实际上是一种过程－响应模型。文内较为系统地介绍了全球旋回地层学的基本原理和应用方法，并借用两个实例阐述了全球旋回地层学在预测盆地中的地层厚度、岩相分布和碳酸盐岩生长方式等方面的应用。
Cyclic deposition on a global scale is the product of the changes in sea-level,tectonics,climate, geography and depositional features of the global or the combination of these. Globalcyclostratigraphy is defined as the study of cyclic depositional patterns in the geologic recordproduced by the interaction of climate and tectonic processes. It is a stratigraphic branchwhich is developed based on the sequence stratigraphy. Stratigraphic changes through estimating sediment types and depositional environment in a basin can be predicted by means ofthe global cyclostratigraphy. This paper introduces systematically the fundament of theglobal cyclostratigraphy and application to predicting the stratigraphic thickness,lithofaciesdistribution and growing patterns of carbonate
