本文较详细地介绍和论述了土壤年代学方法及其测年原理,以及该方法的国内外研究现状和发展应用前景.作者将该方法的基本思路引入榆木山和阿尔金山山前地区的活动构造测年工作,并初步建立了土壤CaO、CaCO3和CaCO3累积指数值与发育年代之间的定量计算关系式,统计得到了土壤中砾石钙膜的平均累积速率.通过回检和应用对比分析,认为土壤年代学方法适用于中国西北地区,并具有广阔的应用前景.
This paper introduces and discusses in detail soil geochronology and its dating principles, as well as the current research status and development prospects of the method at home and abroad. The author introduced the basic idea of this method into the active tectonic dating of the Yumu Mountain and the Altun Mountains, and initially established the quantitative relationship between the cumulative index of soil CaO, CaCO3 and CaCO3 and the developmental age, Average accumulation rate of gravel calcium film in soil. Through the comparison of backtesting and application, we think that the geochronology method is suitable for the northwestern China and has a broad application prospect.
