Eclogite.
Eclogite (high pressure origin, with tectonic introduction from upper mantle depths) pod enclosed within amphibolite-facies gneisses.
Two-distinct generations of amphibole are recognized :
- Early amphibole co-existing with garnet and clinopyroxene (hydrous-eclogite-facies),
- Later symplectitic amphibole co-existing with plagioclase formed by retrogressive amphibolitization.
Associated with the eclogite pod are a quartz vein formed by pyroxene carbonation and a barroisite pegmatite.
