齐宝林与《地质与勘探》编辑部等,都曾提出根据钙镁碳酸盐岩中的CaO、MgO含量换算其主要矿物成分并确定岩石类别的图解法(见《地质科技》1977年第4期与冶金工业出版社出版《野外地质工作参考资料》一书).前者给出了维什尼亚科夫三角形图解上各岩石类型区分界点的CaO、MgO含量值;后者则在同种图解上给出了等CgO、MgO含量线.实践证明,上述图解法是可取的.尤其是后者,较为直观而为广大地质工作者所采用. 笔者在使用过程中,鉴于该图解的三个端元
Qi Baolin and the editorial department of “Geology and Exploration” have all proposed the graphic method of converting the main mineral components according to the CaO and MgO contents of calcium-magnesium carbonate rocks and determining the rock types (see Geological Science and Technology, 1977, No.4 Period and Metallurgical Industry Press published “Field Geological Reference Materials,” a book.) The former gives the Visnick Cove triangle diagram of the rock types of the boundaries of the CaO, MgO content values; the latter in the same species Graphically given the CgO, MgO content line. Practice has proved that the above graphic method is desirable, especially the latter, more intuitive and for the majority of geological workers used in the process of using the author, in view of the diagram of the three End yuan
