Uhp Kyanite Eclogite Associated With Garnet Peridotite

Uhp Kyanite Eclogite Associated With Garnet Peridotite Jun 01, 2015 Kyanite eclogites and garnet pyroxenites, forming dykes or veins in garnet peridotite, are well known from several UHP metamorphic terranes, for example, in the Scandinavian Caledonides Griffin et al., 1985, indicating melt intrusion into peridotites while these were still in the mantle Brueckner and Medaris, 2000, Medaris, 1980.Jun 01, 2015 Kyanite eclogites and garnet pyroxenites, forming dykes or veins in garnet peridotite, are well known from several UHP metamorphic terranes, for example, in the Scandinavian Caledonides Griffin et al., 1985, indicating melt intrusion into peridotites while these were still in the mantle Brueckner and Medaris, 2000, Medaris, 1980.Mar 01, 2016 Petrography of kyanitegarnet schists from the Variegated Formation. In the vicinity of the town of Chepelare, kyanitegarnet schists outcrop as decimeter to meter sized packages found in close association with marbles, amphibolites, and gneisses, although contacts are often masked by vegetation or erosion.
