| 摘 要： | 粘土矿物普遍存在于各种类型的沉积物和沉积岩中。作为次生矿物，粘土对环境的变化极为敏感，因而粘土矿物的沉积分异、组合特征、矿物成分及其含量和矿物结晶度都从不同的角度记录了粘土矿物形成过程中各种环境因素的变化。这些对恢复古环境，研究全球变化具有重要的指示意义

| Abstract: | Clay minerals are distributed in different types of deposits and sedimentary rocks. As secondary minerals they are highly sensitive to environmental changes. The characteristics of clay minerals such as sedimentary differentiation, composition and assemblage, crystallinity and stable isotope has recorded the information of environmental change during the processes of clay minerals formation.These information will help to reconstruct the paleoenvironment and have huge significance in global change research. |
