Spinel group minerals are excellent indicators of geological environments(tectonic settings). In 2001, Barnes and Roeder defineda set of contours corresponding to compositional fields forspinel group minerals. Geologists typically use this contours to estimatethe tectonic environment where a particular spinel compositioncould have been formed. This task is prone to errors and requirestedious manual comparison of overlapping diagrams. We introducea semi-automatic, interactive detection of tectonic settingsfor an arbitrary dataset based on the Barnes and Roeder contours.The new approach integrates the mentioned contours and includesa novel interaction called contour brush. The new methodology isintegrated in the Spinel Explorer system and it improves the scientist?sworkflow significantly.
