MELT INCLUSIONS IN MINERALS OF SCAPOLITE-BEARING GRANULITE (LOWER CRUSTAL XENOLITHS FROM DIATREMES OF THE PAMIRS)

Abstract

The study of scapolite-bearing eclogite-like rocks and granulites, experimental data, and finds of scapolite in igneous rocks showed that high-Ca scapolite can be of both metamorphic and magmatic origin under the high partial pressure of CO2 and/or SO3 in the fluid or melt. This communication presents the first direct data on scapolite crystallization in the lower crust with participation of CO2-saturated melts.
