为了形象地表达地球化学测量所取得的成果,需要编制各种类型的地球化学图。目前用于编图的方法很多,移动平均分析、趋势面分析及常被采用的勾绘等含量线的方法等,多用于单元素地球化学图的编制。而各种形象地用符号、图式表示含量变化的编图方法,虽然也用于多元素
In order to vividly express the achievements of geochemical measurements, various types of geochemical maps need to be compiled. At present, there are many methods for compilation of graphs, such as moving average analysis, trend surface analysis, and the method of content lines such as drawing and drawing, which are often used for the preparation of single element geochemical map. The various images with symbols, schemas that change the contents of the coding method, although also used for multiple elements
