Abstract: Clay minerals are widely applied in reconstructing paleoclimate, and many analysis methods are involved. Among them the X-ray diffraction analysis(XRD) is mainly used to confirm clay mineral assemblages and their crystallinity; chemical analysis and electronic microscope are used to study the source, the genesis and the evolvement process of clay minerals; radioactive isotopes analysis can make up the relationship between the time and space which is based on the climate index and the chronology; Hydrogen and oxygen isotopes also provide important evidence for reconstructing paleoclimate. This paper summarizes what paleoclimate information is contained in clay minerals, and it is intent to use clay minerals synthetically as the means to reconstruct paleoclimate.

Key words: Clay minerals, paleoclimate, XRD, chemical analysis, electron microscopy, isotopes
