Abstract :
The gabbroic bodies are outcropped in the East and south-west of Hourand (East of Kaleybar) and in the East Azarbaijan province. The gabbroic body of Leghlan forms frequent sills injected in the Upper Cretaceous-Paleocene flysch deposits. The gabbroic body of Hashtsar along with associated pyroxenite were injected into these deposits. The mineral composition of the gabbroic body of Leghlan is plagioclase, clinopyroxene, potassium feldspar and biotite, and the major minerals of the gabbroic body of Hashtsar includes plagioclase, clinopyroxene and amphibole. Plagioclases in gabbroic body of Hashtsar (anorthite) is more calcic than those in the gabbroic body of Leghlan and show no chemical zoning. The composition of clinopyroxene in both bodies is in the range of diopside and amphiboles in gabbroic body of Hashtsar are pargasite to tschermakite. The parental magmas of these bodies, based on mineral chemistry and composition of clinopyroxene, was shoshonit and the melting occurred at a rate of about 5% of the enriched spinel-garnet lherzolite mantle and with garnet in the residue. The rocks were developed in a volcanic arc setting.
