摘      要：Crystalline and melt inclusions were studied in garnet,diopside,potassium feldspar,and sphene from the garnet syenite porphyry of the carbonatite-bearing complex Mushugai-Khuduk,southern ***,clinopyroxene,albite,potassium feldspar,spheric,wollastonite,magnetite,Ca and Sr sulfates,fluorite,and apatite were identified among the crystalline inclusions. The melt inclusions were homogenized at 1010～1080℃and analyzed on an electron ***,salt,and combined silicate- salt melt inclusions were *** melts show considerable variations in SiO_2 concentration(56 to 66wt% ),high Na_2O+K_2O (up to 17wt% ),and elevated Zr,F,and C1 *** terms of bulk rock chemistry,the silicate melts are alkali *** thermometric experiments,salt melt inclusions quenched into homogeneous glasses of predominantly sulfate compositions containing no more than 1.3wt% SiO_*** melts are enriched in alkalis,Ba,Sr,P,F,and *** investigation of the silicate and salt melt inclusions in minerals of the garnet syenite porphyries indicate that these rocks were formed under influence of the processes of crystallization differentiation and magma separation into immiscible silicate and salt(sulfate)liquids.
