Abstract

The HASAN SALARAN GRANITOID COMPLEX consists of two distinct granitoid types with various genesis. This complex is situated in NW of the SANANDAJ-SIRJAN METAMORPHIC BELT. Major stratigraphic units of the study area and its adjacent areas are Permian limestones, andesitic-basaltic lavas of Jurassic age and shale, sandstone, limestone and andesitic volcanic rocks of Cretaceous period. Two granitoid plutons are distinguished: The first type is G1 granitoid which is mainly composed of alkali-feldspar granite, syenogranite and alkali-feldspar quartz syenite. This complex displays geochemical characteristics of the ferroan alkalic to ferroan alkali-calcic, peralkaline, A-TYPE and A2 subtype. The intrusion under study shows mineralogical and geochemical characteristics of post-orogenic or post-collision (within plate) granites. Also the mineralogical and geochemical properties indicate an enriched mantle origin with contribution from the crust in generation of source magma of this intrusion. The second type is G2 granitoid is composed of monzogranite, granodiorite and tonalite. The above mentioned complex has calc-alkaline, magnesian calcic, metaluminous with I-TYPE geochemical characteristics. The presence of abundant mafic microgranular enclaves points to mingling of mafic and felsic magmas and is responsible for generation of G2 granitoid magma, which may be formed in a volcanic arc environment.
