There are many working programs with different functions in GeoKit such as Scatter for Geochemistry, REE Pattern Diagram, Trace Element Ratio Spidergram, Calculation for CIPW Normative Minerals and Petrochemical Parameters, PbSrNd Isotope Parameters and so on. The GeoKit is friendship in interface and convenient in use and is a useful tool software for geological and geochemical workers.
