Based on the Symposium on Magma Transport and Storage from Source to Eruption Site, held at the 28th International Geological Congress, in Washington DC, July 9-19, 1989. The symposium brought together scientists working from a broad range of perspectives to explore the processes, pathways and mechanics of magmatic movement, combining their individual focuses into a unified theme. Combines treatments of the current research on magma movement in the earth's mantle, oceanic and continental crusts and volcanic centers based on approaches from continuum mechanics, fluid dynamics, heat transfer, experimental high-pressure geophysics, seismology and seismic tomography, observational volcanology and geodesy, field and structural geology. Chapters blend review material with new research results to promote accessibility and provide a measure of self-containment.
