Generating magmas in the mantle


In this work, we are primarily interested in understanding where magmas form in the mantle.  We are currently interested in the generation of arc magmas in the mantle.  What modulates the depth of magma generation in arcs?  How does the thickness of the over-riding plate control melt generation?  Are there important feedbacks in this process that limit melting or promote melting?  What does the migration or lack of migration of the arc front tell us about magmatism at depth?  We are also interested in what controls the origin and fate of magmas in intraplate environments.
