  The volcano of Kuh-e-Gharineh is one of the volcanic areas of Ghorveh-Tekab in Sanandaj - Sirjan belt andlocated in Ghezelche Kand area. guartz xenocryst, plagioclase and granitoid xenolithe are seem in thecomposition of these rocks.Phenocrysts, xenocrysts, xenolithe are seem in a backgrand of microcrystalline withporphyric texture and microlytic matrix to glassy vesicular. On the basis of conducted petrographic researches,all rocks are consisted of basalt, olivine basalt and andisi basalt compounds. According to geochemical studies,the studied alkaline basalt rocks (ultrapotassic) are categorized as intraplate alkaline shoshonitic rocks. Thenegative and positive anomalies of normalized patterns of incompatible rare elements show the contaminationwith the crust and the phenomenon of assimilation. The analysis of the portion of the LILE)Litofil Ion LargElements(, HFSE)High Field Small Elements(, and REE )Rare Earth Elements( elements shows a sign of anenriched source similar to OIB)Ocean Island Basalt( oceanic basalt and also considers the role of upper /lowercrusts to be more effective than that of the subcontinental lithosphere in magmas‌contamination.
