Download & useful links
Download the latest version of the program (Version 2020-02-24) here:
This version updated to include thermodynamic data file 6.3.3. and meemum 6.8.9. therefore the latest HGP solution models are now available including Ti in Melt amongst many other changes. To see an example of how to use this consult the project file "Example_HGP".
*Caution R version 3.6.0 or higher recommended for optimal functioning
**Caution I am currently adding a routine to approximate trace elements supersolidus, this functionality is still in progress
Within the latest Rcrust version you will find an updated manual labelled "Getting Started (Rcrust Manual)" which takes new users through 3 practice examples to become familiar with the program, in addition there is a pdf file called "Summary" which provides a broad overview of features to refresh experiences users of the modelling procedure and features available.

Analysing outputs with GCDkit
The GeoChemical Data ToolKIT, is a system for handling and recalculation of whole-rock analyses from igneous rocks. GCDkit can directly access outputs from Rcrust providing a highly efficient means of analysing geochemical results.

Writing functions in R
R is a simple easy to use freeware language and environment for statistical computing and graphics. Knowledge of R will not only help the writing of custom functions in Rcrust but also the quick interpretation of results using GCDkit. An extensive resource on the subject has been published by
