Abstract: 

Fell down particles (xenoliths) of garnet–biotite-kyanite schist cropped out in the northwest of the Qori regional metamorphosed complex, Neyriz, emplaced in the southern part of the Sanandaj-Sirjan metamorphic zone, when the Talle-Pahevani anorogenic magmatic intrusion, leuco-quartz diorite-anorthosite in composion, was injected into this part of the complex about 170 Ma years ago. These xenoliths underwent severe contact metamorphic event. Some schist xenoliths endured small degrees of partial melting; hence, migmatite textures were expanded in these xenoliths, and also extraction and accumulation of some partial melts were formed the small peraluminous granite patches.
Field observations, microscopic studies, and chemical data show that there are close relation among the schist xenoliths, partial melting, and occurrences of the migmatites and small peraluminous granite patches. Decrease in SiO2, Na2O, and K2O contents, increase in Al2O3, TiO2, FeO*, and MgO contents, and relation of the elemental ratios such as Sr/Y, K/Sr, Lan/Ybn, Lan/Smn, and Gdn/Ybn, suggest that the formation of granite patches were extracted from diatexitic migmatite xenoliths. Therefore, muscovite and biotite-dehydration melting caused to be changed schist xenoliths to the migmatite and formation of the small granite patches.
