Fluid and melt inclusions in deep-seated xenoliths from the Kongarovskaya pipe (Khakasia, Russia)

摘要

Basanites of the Kongarovskaya pipe (North-Minusinsk depression, SW framing of the Siberian Platform, Khakasia, Russia) contain a lot of deep-seated xenoliths (lherzolites, pyroxenites and augite megacrysts) up to 25 cm in size. Secondary fluid and melt inclusions were found in clinopyroxene of spinel werhlite (Cpx + Ol + Sp) and garnet websterite (Cpx + Opx + Gr) xenoliths. Temperature estimations for these xenoliths paragenesis corresponds to 980-1147°C (Sobolev et ah, 1988). Secondary melt and sulphide inclusions also occur in augite megacrysts.
