A new computer program TecDIA written in Java, for the application of 35 previously-defined multidimensional diagrams for the tectonomagmatic discrimination of intermediate and acid magmas is briefly described. A detailed Readme document is presented in the Supplementary Electronic Material file. As an innovation, this program provides a ready to publish report containing a synthesis of all diagrams, including the total percent probabilities.
The use of this program is illustrated by two examples of the Bohemian Massif (Czech Republic) for older Carboniferous (granitoids of the Central Bohemian Pluton) and younger Late Carboniferous-Early Permian igneous rocks (volcanics from late Variscan continental basins and granitoids of the Žulová Pluton). According to the results, the tectonic setting for the Early Carboniferous rocks was collisional, whereas for the Late Carboniferous-Early Permian igneous suite it was either a collision or a transition from collisional to a within-plate setting. The acid rocks probably dominated by a crustal component may provide a somewhat different result as compared to the intermediate rocks. TecDIA freely available from http://tlaloc.ier.unam.mx will certainly be useful for all interested in applying these 35 multidimensional diagrams.
