Melt Inclusions in Minerals of Scapolite-Bearing Granulite (Lower Crustal Xenoliths from Diatremes of the Pamirs)

摘要

The study of scapolite-bearing eclogite-like rocks and granulites, experimental data, and finds of scapolite in igneous rocks showed that high-Ca seapolite can be of both metamorphic and magmatic origin under the high partial pressure of CO_2 and/or SO_3 in the fluid or melt. This communication presents the first direct data on scapolite crystallization in the lower crust with participation of CO_2-saturated melts.
