在古环境和古气候的重建中,粘土矿物和碳-氧同位素、孢粉、树轮、冰芯等代用指标一样具有同等重要的地位。在没有地质构造运动影响时,气候是影响粘土矿物形成的主要因素,沉积物中的粘土矿物可用来分析古气候和古环境。粘土矿物及其组合可以独立或作为主要指标反映气候和环境变化,并已应用于高分辨率的晚第四纪地层的气候环境研究中。粘土矿物在很短的时间内也会发生明显地变化,不仅可以反映千年-百年尺度的气候环境变化,而且也可以反映几十年尺度的古气候环境变化过程。粘土矿物与其它指标对同一气候环境响应的相位差有待深入研究。不同的半定量分析方法测量出的同一剖面中粘土矿物的含量变化趋势和特征具有一致性。
In the reconstruction of paleoenvironment and paleoclimate, clay mineral has the same important status as those of carbon-oxygen isotope, pollen, tree-ring and ice core. In the absence of geological tectonic movement, climate is the main factor affecting the formation of clay minerals. Clay minerals in sediments can be used to analyze paleoclimate and paleoenvironment. Clay minerals and their assemblages can reflect climate and environmental changes independently or as primary indicators and have been used in high-resolution climate studies of late Quaternary formations. Clay minerals also change obviously in a short period of time, not only reflecting the climatic and environmental changes in the centennial scale but also reflecting the decadal paleoclimate and environmental change processes. The phase difference between clay minerals and other indicators responding to the same climatic and environmental needs to be further studied. Different semi-quantitative analysis method to measure the same profile of clay mineral content trends and characteristics of the same.
