Abstract

As a major component of continental crust, granites have been served as the most important subject in geology. Based on advancements obtained during past decades, this paper provides a comprehensive overview about the issues related to granitic formation. As for genetic types, the classifications between I-, S-and A-type granites are sometimes difficult, especially for those of highly fractionated rocks. It is stated that the concentrations of zirconium in whole-rock and titanium in zircon can be used to provided information on the temperature of partial melting and magma crystallization, but the pressure under which the source partially melted is hard to estimate. The granites are mostly occurred in the subduction zones and post-orogenic extensional settings, where the inputs of volatile and heat resulted in crustal partial melting of orogenic roots, and then the formation of granites. The traditionally used geochemical diagrams for the tectonic discrimination could not get right answer in most cases. This paper also presents a concise summary about the recent achievements of granitic study in China. Finally, potential breakthroughs for the Mesozoic granites in eastern China are explored.
