Comparative studies on the Tectonics and Volcanism of Circum-Pacific Arcs

Abstract

Foreword (Part B)
The features of the Mexican Arc (Trans-Mexican Volcanic Belt, TMVB) are quite unusual (Delgado, 1994). We now have a better picture of the morphology of the subducting plate beneath southern Mexico (Pardo and Suarez, 1994), but several questions remain to be solved e.g., the anomalous chemistry and distribution of volcanic rocks (lamprophyres on the volcanic front in western TMVB) along the arc (e.g. Lange and Carmichael, 1992).
