Granitoids are the dominant component of the continental crust. This session examines all aspects of granite petrology and geochemistry: the formation and extraction of melts; the processes that control the evolution from melt to granite; the emplacement, cooling and textural development of granites; the ore systems associated. Contributions from the fields of experimental petrology, geochemistry, mineralogy, field studies, etc. are welcome in this session. A particular focus of this session is the long term evolution of granitic magmatism, from the past to the present.
