Research and development of the lithogeochemical plot information analysis support system

Based on the lithogeochemical and interdisciplinary research methods, this study described the processes of lithogeochemical data processing and data analysis with the thinking of a geochemist, and designed a rational and effective algorithm. Plots in the system were used in geochemical data processing, which could provide a simple, direct and convenient way to reveal the geological regularities in nature. According to the data features and analyses of the two-variable and three variable plots, the data for calculation were subdivided into related parameter calculation of major and trace elements, standard mineral calculation and some associated calculations. Finally, this study developed a geochemical plots mapping system that achieved the automation of data management, graphic selection, plots calculation and graphic rendering.
