***************************************************************** From: Johan Varekamp <jvarekamp@xxxxxxxxxxxx> ***************************************************************** Dear All, At AGU fall we have organized a session on continental arc volcanism in honor of Jim Luhr, who died in January 2007. As many of you know, Jim worked extensively on Mexican volcanoes but also in many other arc environments worldwide (e.g., Italy, Kuriles). We encourage you to submit papers to this session in memory of Jim Luhr and the carefully crafted science that he produced. Joop Varekamp Subduction Volcanism at Continental Margins This session has its focus on volcanism at the edge of continents, as exemplified (but not exclusively) by the Mexican volcanic belt. Mass flow in subduction environments from the mantle to the surface is influenced among others by differentiation processes, crustal contamination, degassing, magma ascent rates and eruption type. Presentations are invited on volcanic products ranging from volcanic rocks, melt inclusions in crystals, and gases to xenoliths that provide insight into the origin, evolution and transport processes of such continental arc magmas. Fundamental topics to be addressed may include 'the role of subduction volcanism in the formation of the continents', 'estimates on the amount of crustal contamination in a volcanic suite', 'the composition of the mantle wedge at continental margins', 'the volatile budget in specific subduction zones', and 'the application of the stratigraphic and petrologic history of a volcano to better predict future eruptions'. This session invites contributions thematically linked and/or inspired by the lasting and fundamental work of James F. Luhr. Conveners: Anne H.
