Carbon , hydrogen oxygen isotope studies on imbedded old tree ring and paleoclimate reconstruction
埋藏古木树轮碳氢氧同位素研究与古气候重建
Among them the x - ray diffraction analysis 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
其中， x射线衍射分析主要用来确定黏土矿物组合及其含量以及某些黏土矿物的结晶度化学分析电镜分析主要用于黏土矿物的来源成因演变过程的研究放射性同位素的研究使气候指标和年代学建立起时间和空间上的联系而氢氧同位素分析亦能对古气候重建提供重要佐证。
