Physical properties of upper mantle rocks in relation to geodynamic processes



A major target of research during the Geodynamics Project is the study of the physical properties and processes of the earth's interior with the objective of establishing a dynamical model of plate tectonics. The principal source of information about the physical state of the earth's interior comes from seismological investigations. The ability to translate seismological and other geophysical data into information regarding composition, phase, temperature, and stress state in the earth's interior requires extensive laboratory experimentation on natural and synthetic materials and theoretical equations with which to extrapolate these laboratory data to mantle conditions.
