GCDkit is a program for management and recalculation of whole-rock geochemical data for igneous and metamorphic rocks. To address the major drawbacks of the existing geochemical software, we have developed a new package called Geochemical Data Toolkit for R ( GCDkit).
The solution: Geochemical Data Toolkit ( GCDkit) For more complicated calculations the worksheet soon becomes too complex and prone to errors. Concerning spreadsheets, they have low efficiency for repeated tasks, poor quality of graphic output, as well as limited protection of the primary data. Even if it is, any modifications or additions to the original program can be tedious, or impossible for legal reasons.

In addition, the usability of many of these tools is hindered by the fact that it is often difficult to determine exactly which algorithm has been employed, because documentation is not detailed enough and it is not a common practice to make the source code available. Most of these otherwise useful programs are, however, not well suited to management and interpretation of larger datasets. An alternative preferred by many researchers are spreadsheets, sometimes aided by special macros ( Sidder, 1994 Su et al., 2003). NewPet- Clarke et al., 1994 IgPet- Carr, 1995 MinPet- Richard, 1995 PetroGraph- Petrelli et al., 2005).

The interpretation of whole-rock geochemical data is not different, as it requires complex and time-consuming calculations, which on PC compatible computers are mainly performed using dedicated, stand-alone programs (e.g.

Such an approach leads inevitably to a flood of numerical data, which have to be analysed by an appropriate software tool. The need to quantify aspects of the world in which we live is inherent in contemporary scientific thinking. INTRODUCTION The challenge: geochemical recalculations and plotting

The product is actively maintained and updated to provide additional functionality Unix/Linux and Mac OS versions are being developed. GCDkit is available as Free Software under the terms of the Free Software Foundation's GNU General Public License and can be downloaded from. The system can be further expanded by means of plug-in modules that provide specialist applications. The graphical output is publication ready but can be further retouched if required. binary and ternary graphs, Harker plots, spider plots, and several dozens of classification and geotectonic discrimination diagrams).
Included are a variety of calculation and normative schemes, for instance CIPW and Mesonorm, as are the common geochemical graphs (e.g. Data management tools include import and export of data files in a number of formats, data editing, searching, grouping and generation of subsets. GCDkit was designed to eliminate routine and tedious operations involving large collections of whole-rock data and, at the same time, provide access to the wealth of statistical functions built into R. It is built using the Windows version of R, which provides a flexible and comprehensive language and environment for data analysis and graphics. Geochemical Data Toolkit ( GCDkit) is a program for handling and recalculation of geochemical data from igneous and metamorphic rocks.
