Regional metamorphism and P-T evolution of the Ross Orogen in northern Victoria Land (Antarctica): a review
The main focus of this paper is on the petrological evolution of medium- to high-grade metamorphic units in the Wilson Terrane, the westernmost lithotectonic unit of the Ross Orogen in northern Victoria Land. The petrological data set is reviewed for all areas where P-T-t paths have been reconstruct...
