...W. McCarthy; M. S. Petronis; R. J. Reavy; C. T. Stevenson Abstract Granitoid plutons account for much of the continental crust and are critical in the generation of several economic resources. Despite over a century of research, the fundamental process by which large felsic bodies intrude remains...

... Ma) and find ourselves in a rare exposure of the plutonic roots of ancient central volcanoes (Vesturhorn, Slaufrudalur, Austurhorn). These intrusions, exposed by glaciation and visible along the coast, reveal the complex interactions of mafic, intermediate, and felsic magmas that likely occur beneath...
