Garnet-Rich Veins in an Ultrabasic Amphibolite from NE Sardinia, Italy: An Example of vein Mineralogical Re-Equilibration during the Exhumation of a Granulite Terrane

A complex system of mono- and polymineralic centimeter-thick veins occurs within the ultrabasic amphibolites of Montigiu Nieddu hill in northeastern Sardinia, and they are filled with garnet, amphibole, chlorite, and epidote. Some garnet-rich veins are margined by an amphibole layer at the interface...
