‘I fact, just about everything that was taught as recently as ten years ago about granitic magmatism has been turned on its head.’1 So concludes John Clemens in his overview paper about the origin of granite, published in the UK in the Proceedings of the Geologists’ Association. In his introduction to Clemens’s paper and the accompanying discussion, editorial board member W.J. French explains t...

Post-rift magmatism associated with seafloor spreading (∼32 Ma to ∼15 Ma) and post-spreading tectonics (from the present day) is widely recorded in South China Sea (SCS). However, phenomena originating this are still under debate, hindering a full understanding of SCS’ evolution. In study, extensive voluminous magmatic bodies northern SCS investigated based on integration 3D/2D seismic borehole...

Between the western and the eastern parts of the southern Alaskan Sanak–Baranof belt there exist variations in pluton spacing, geochronology, geochemistry and metamorphism. All such characteristics can be explained by increase in heat flux towards the eastern parts of the belt. Despite such differences, the initiation of magmatism propagated eastward at a constant rate of 19 cm/year throughout ...
