14过渡矿物是广泛发育的典型成土作用产物,其矿物学特征及含量变化不仅能记录成土时期的气候、环境条件,也可以作为这些土壤发生分类和类型区分的依据。通过对有关14过渡矿物研究成果系统全面的分析,阐明了这种过渡矿物的谱学特征、层间离子类型、鉴定依据及其成因,并在此基础上提出对14过渡矿物的鉴定实验流程。此外,高分辨透射电子显微技术的应用给14过渡矿物的研究提供了极大的保障,利用高分辨透射电子显微镜可以研究14过渡矿物的形成、转化关系。14过渡矿物对气候环境十分敏感,且形成于特征的干湿交替、适度的风化及弱酸性环境条件,因此,这种过渡矿物有望作为成土时期的气候环境代用指标。
14 Transitional minerals are typical products of extensive soil-forming activity. Their mineralogical characteristics and variations not only record the climatic and environmental conditions of the soil-forming period but also serve as a basis for the classification and type discrimination of these soils. Through the comprehensive analysis of the results of the 14 transitional mineralization, the author has elucidated the spectral characteristics, the type of interlayer ions, the identification basis and their causes of this transitional mineral. On this basis, Process. In addition, the application of high-resolution transmission electron microscopy provides a great guarantee for the study of 14 transitional minerals. The formation and transformation of 14 transitional minerals can be studied by using high resolution transmission electron microscopy. 14 Transitional minerals are very sensitive to climatic and environmental conditions, and formed in the characteristics of alternating wet and dry, moderate weathering and weak acid environmental conditions, therefore, this transitional mineral is expected to serve as proxy indicator of climatic and environmental conditions during the soil formation.
