FLUID INCLUSIONS IN ECLOGITES OF LARGE CA UCASUS

The eclogites of Peredovoy range of Large Caucasus subjected to maxima l metamorphic alteration at 700-degrees-C and 18 kbar pressure are fou nd to incorporate the fluid inclusions in quartz from the eclogitic as semblage. Physical peculiarities of fluid in inclusions are correspond ing to P-T conditions of the amphibolitic facies (6-10 kbar, 600-degre es-C). It is suggested that metamorphogenic fluid portions were captur ed by quartz within its regressive recrystallization.
