| Реферат: | eng: Data on mineral-hosted inclusions indicate that the charoite rocks crystallized in a heterogeneous medium of carbonate-silicate and carbonate melts, gaseous and H2O-salt fluids. Our results indicate that the early rock-forming minerals of the charoite rocks started to crystallize at high temperatures (>800 degrees C), and crystallization may have terminated at lower temperatures (600-450 degrees C). Data on the melt and fluid inclusions confirm the conclusion that the charoite rocks are of magmatic origin. The facts that these rocks are typically found as vein- and lens-shaped bodies, the composition of these rocks does not correlate with the composition of the host rocks, and the occurrence of chilled fine-grained domains of the charoite rocks also suggest that these rocks crystallized from magmatic melt.
