GDA (Geochemic al Data Analysis) is a comprehensive IBM PC-based geochemical data processing system. It is designed to use whole-rock geochemical data retrieved from the ORACLE database, but can be adapted for other databases, or data can be entered into files from the keyboard. The programs are written in FORTRAN 77 (microsoft compiler) and use the MicroGlyph Systems SciPlot graphics package for plotting. The system includes facilities for generating plots (histograms, XY plots, triangular plots, spidergrams, box-whisker plots, etc.), calculating statistical functions (e.g., mean, standard deviation, regression lines, correlation coefficients and cluster analysis) and CIPW norms, printing tables, and carrying out petrogenetic modelling calculations. Plots can be displayed on a PC screen for inspection and editing before being output to a plotter or other device. Other programs allow samples to be assigned to groups for plotting purposes, and allow editing and merging of datafiles.
