Norway - Verpeneset eclogite Norway - Verpeneset eclogite Norway - eclogite adjacent to Verpeneset body Norway, Western Gneiss Complex  Homogeneous bimineralic garnet-omphacite eclogite, Western Norway. [photo: A L Wain] Norway, Western Gneiss Complex  Eclogite facies, ultrahigh pressure division. Metabasic garnet-omphacite-orthopyroxene eclogite. Coesite has been recorded as inclusions in minerals from this rock. Western Norway. [photo: A L Wain]
Norway, Western Gneiss Complex  Eclogite facies, partly retrogressed. Margin of metabasic eclogite body against amphibolite-facies gneiss. Fresh eclogite on the right grades into darker-coloured rock in which omphacite is replaced by diopside-plagioclase-amphibole intergrowths. Western Norway. [photo: A L Wain] Norway, Western Gneiss Complex  Eclogite facies. Contact between metabasic garnet-omphacite eclogite (below) and eclogite-facies metasedimentary rock (garnet kyanite phengite gneiss), with very little retrogression. Western Norway.

Western Alps: Val Clavalite, Aosta valley  Blueschist/eclogite facies (transitional). A metabasic rock consisting of blue glaucophane, green omphacite, red garnet porphyroblasts with long included prisms of glaucophane, and rusty-brown carbonate (ankerite). Aosta valley, Western Alps. Western Alps: Val Clavalite, Aosta valley Western Alps: Val Clavalite, Aosta valley Western Alps: Val Clavalite, Aosta valley  Eclogite facies. Metabasic gneiss consisting of interbanded eclogite and glaucophane-bearing eclogite. Aosta valley, Western Alps. Western Alps: Val Tournanche
Western Alps: Val Tournanche  Eclogite facies. Foliation surface of eclogitic metabasic schist with garnet, omphacite, clinozoisite and needles of dark glaucophane. Lago di Cignana, Western Alps, Italy. Western Alps: Lago di Cignana, Val Tournanche Western Alps: Val Tournanche Western Alps: Lillianes, Sesia Zone  Eclogite facies (partly retrogressed). Gneiss probably derived from intermediate igneous rock, with omphacite-bearing assemblage now partly retrogressed to albite and actinolite (greenschist facies). Sesia Zone, Western Alps, Italy. Western Alps: Lillianes, Sesia Zone  Eclogite facies. Thin folded metabasic layer with green omphacite enclosed in high-pressure schist. Sesia Zone, Western Alps, Italy.
Western Alps: Lillianes, Sesia Zone Western Alps: Monviso, Pian del Rei, Valle Po Western Alps: Monviso, Pian del Rei, Valle Po  Eclogite facies. Banded eclogite, possibly derived from ocean-floor basalt, cut by a small shear zone that has allowed fluid to enter and cause retrograde blue (Na-) and green (Ca-Na-) amphibole growth. Monviso unit, Italian Western Alps. Western Alps: Dora Maira massif Western Alps: Dora Maira massif  Eclogite facies, ultrahigh pressure division. Schist with pale pink Mg-rich garnet, phengite, kyanite and quartz. The quartz is all recrystallised from coesite, the high-pressure polymorph of SiO2, and coesite relics can be found inside the garnets. Dora Maira massif, Western Alps, Italy.
Western Alps: Schistes Lustres, Col Agnel  Carpholite porphyroblasts in schist Western Alps: Queyras, France Western Alps: Queyras, France Western Alps: Queyras, France  Blueschist facies metagabbro, Western Alps, France. Coarse-grained gabbros occur as blocks in the blueschist-facies 'schistes lustres' of the Western Alps. Here igneous augite is fractured and rimmed by dark blue glaucophane. Western Alps: Queyras, France  Sub-blueschist facies. Yellowish lawsonite and quartz in a vein cutting Permian volcanics, Western Alps, France.
Oman, As Sifah: eclogite-facies schist  Eclogite facies, low T. Metapelitic schist with large garnet porphyroblasts and schistosity comprising greenish phengitic muscovite. These are rocks subducted beneath the Oman ophiolite.
