Using this system, the data can be loaded, individual analyses grouped into coherent groups or searched according to various criteria. They can be plotted into commonly used classification diagrams (e.g. Harker plots, TAS, AFM, R1-R2) as well as a variety of user-defined plots (binary and ternary plots, multiple plots, spider diagrams).
Moreover, some basic statistical methods are implemented (both for the whole data set and individual groups) using a fraction of the power built in R. Included are the descriptive statistics, boxplots, histograms, principal component and cluster analysis. GCDkit also makes possible the most common normative calculations to be performed.
Functions for interpreting radiogenic (SrNd) isotopic compositions have been also included  (calculating Sr and Nd initial compositions, Nd model ages etc.).
The long-term aim is to built a single, coherent and eventually platform-independent system with high-level plotting capabilities for interpretation of whole-rock geochemical data, that would be straightforward to use by ordinary users but, at the same time, easily expandable by the more demanding ones.
