摘　　要：定量地层学是利用统计学的观点，使定性的资料通过数学的方法，变为定量的资料。通过对川东北达县地区的达县铁山金窝剖面和开江温泉剖面应用定量地层学的方法，进行化石事件时限的研究、探讨，为地层的划分、对比提供又一证据。Quantitative stratigraphy applies the statistical viewpoint to transform the qualitativedata into the quantitative data with mathematical methods. Quantitative stratigraphical method is ap-plied to the researches and discussion of the time limits of fossil event in the sections of Tieshan andKaijiang hot spring,Daxian County,northeast of Sichuan Province to provide another evidence for thedivision and correlation of the strata.
