| 摘 要： | 喀斯特地区的泉水和溪流水中沉淀下来的一种次生沉积物，是由碳酸钙过饱和沉淀产生的．碳酸钙沉积或沉积多寡受到多种因素的控制和影响，其中古环境，特别是古气候，影响尤甚．我们通过同位素测年工作，探讨了云贵高原第四纪以来的古环境的演递及其发育历史．

| Abstract: | Calcium carbonate is a kind of secondary sediment from springS and brooks in karst regions,which is formed from deposition of CaCO3 super-saturated water.The formation of calcium carbonatesediment and its amount are controlled and affected by many factors, of which paleoenvironment, especially poleo-climate is one of main conditions controlling its deposition. This poper further exploresthe paleoenvironment evolution of Yunnan-Guizhou plaleau and its development history since the Quaternary by means of analysing isotope dating. |
