Structural and metamorphic control on the exhumation of high-P granulites: The Carvalhos Klippe example, from the oriental Andrelândia Nappe System, southern …
High-pressure granulites are formed within the lowermost continental crust. If exhumation is
driven only by erosion, these granulites will remain at their site of formation indefinitely. Their …
