Vogel, Thomas A.

Our group has been concentrating our recent effort on the origin of silicic magmas in oceanic arcs particularly in areas where there is no evolved continental crust. We have projects in Central America and the Philippines, and recently we have been working on the large volume silicic magmas from the Taupo Volcanic Zone in New Zealand. A basic question that these studies address is "what is the origin and evolution (petrogenesis) of these silicic magmas"? Answering this question will lead to a better understanding of the origin of the continental crust.
