Dr. Marshall's research interests involve the application of a variety of methods of pressure, temperature and age determination to problems in metamorphic petrology, aqueous geochemistry, ore deposits and tectonics. The majority of my research has been focused upon applying these various analytical techniques to metamorphic rocks and ore deposits in order to establish the tectonic histories of the enclosing geological terranes and to develop and refine the genetic models for the ore deposits studied. Pressure-Temperature-time (PTt) studies of ore deposits in conjunction with their regional host units can be a very effective approach as ore minerals and alteration systems have been the subject of extensive thermodynamic study and thus offer a rich source of mineral equilibria useful for PTt determinations.
