| 摘 要： | 碎屑岩的粒度特征和岩石矿物学特征是判别沉积时的自然地理环境、水动力条件、物源和母岩区性质的良好标志,因此,粒度分析和岩矿数据分析是碎屑岩沉积学研究中的一个重要方面。本文在建立粒度和岩矿成分数据库的基础上,设计了编绘粒度分析直方图、累积曲线图、概率图和C-M图以及岩矿成分图解的程序,同时计算统计参数,给出了利用粒度参数建立判别函数,自动判别沉积环境的方法。

| Abstract: | The grain size and petrological and mineralogical characteristics of clasticrocks are good indicators of physiogeographic setting, hydrodynamic conditions,source of sediments and parent rock region during deposition. Therefore, theanalysis of grain size and rock and mineral data is an important part of clasticsedimentological study. Base on the grain size database and rock and mineraldatabase, the grain size histograms, cumulative curves, probability plot and CMdiagram as well as rock and mineral diagrams have been compiled. The grain sizeparameters have been calculated. The authors recommend the methods of estab-lishing the discriminant function and judging sedimentary environments with grainsize parameters. |
