CSpace (Composition Space) is a program aimed at facilitating the graphical and algebraic analysis of data representing compositional coordinates, such as chemical analyses of minerals, rocks or other substances or systems. CSpace focuses on techniques that are particularly suited to the needs of petrologists and mineralogists, but could also prove useful for geochemists and other environmental scientists.
The program also allows interactive visual inspection of composition relations by means of customizable barycentric plots that can be readily made into a variety of composition diagrams.CSpace offers a powerful, yet friendly, implementation of matrix analysis, called the MAW. This is a multipage dialog, or task "wizard", that guides the user through a number of steps from building a composition matrix from a set of cases in the Datasheet, to inspection and analysis of its null-reaction space relationships (i.e. of any linear relations among the composition forming the matrix). The final report may include a full description of the null/reaction space (the set of independent relations in it), a formatted listing of all existing "univariant" relations, and the set of these that imply certain (specified) relationships (e.g. assemblage incompatibility).
