摘    要:粘土矿物是一种广泛分布于地表的沉积物,其组合及含量的变化记录了源区过去气候环境变化的信息。因此,可以根据粘土矿物的含量和组合变化等信息推知其形成时期的气候环境,重建古环境,揭示气候环境演变的规律。粘土矿物是一种研究古环境演化重要的代用指标,在过去气候环境变化研究中有广阔的应用前景。

关 键 词:粘土矿物  古环境  代用指标

Abstract:Clay mineral recording plentiful environmental information of source areas during the course of its formation is one of the deposits distributed extensively on the surface of the earth. According to the contents and assembiling changes of clay minerals, the rules of palcoclimate evolution can be inferred, and the paleoenvironment can be reconstructed. So, clay mineral is one of the important proxy indexes for studying the paleoenvironment evolution, the same as loess, ice core and tree ring, In arid region where there are no other proxy indexes such as loess, ice core, tree ring and so on , clay minerals may be the most important proxy to be used to reconstruct palcoclimate. Thus, it can be seen that clay minerals will have a vast application prospect in the future study on paleoenvironment evolution.
Keywords:Clay minerals  Paloeenvironment  Proxy index
