FastGAPP – Fast Geochemical Analysis Plotting Program

Geochemical studies of igneous rocks are fundamental to classify rock types in terms of main-, minor-, trace element whole-rock chemistry. Together with petrographic observations from thin sections it is possible to classify igneous rocks and to draw interpretations about: The petrogenesis and evolution of igneous rocks. The thermal and barometric conditions in which a primary magma have formed. The magmatic processes that might be involved in the evolution of igneous rocks. The geotectonic environment in which igneous rocks might have formed. Specific programs for the evaluation of geochemical data of igneous rocks are rare and often very difficult to use.…
