The successive stages in the plate-tectonic cycle (see below) produce igneous rocks that have geochemical patterns distinctive for each stage. Consequently, the igneous petrologist is able to use both the major and trace element abundances of rocks to define the possible tectonic environment in which they formed. The metamorphic petrologist can use the bulk
