Mineralogical Evidence for Fluid–Rock Interaction Accompanying Prograde Contact Metamorphism of Siliceous Dolomites: Alta Stock Aureole, Utah, USA

Contact metamorphism of siliceous dolomite in the southern part of the metamorphic aureole of the Alta stock (Utah, USA) produced the prograde isograd sequence: talc (Tc), tremolite (Tr), forsterite (Fo), and periclase (Per). Calcite (Cc)-dolomite (Do) geothermometry and phase equilibria define a ge...
