nezam-abad area is located in southwest of shazand (arak) which is a part of sanandaj-sirjan zone. major intrusive rocks of nezam-abad are quartz diorite and minor amount of granodiorite. leucogranitic, pegmatite dykes and quartz-tourmaline veins were intruded the quartz diorite. quartz diorites are mainly composed of plagioclase, hornblende, biotite, quartz and pyroxene as major minerals. majo...

study area is located in west of iran with relatively rough topography. lithologic units in the region belong from jurassic and cretaccous till recent era. the study area of the alvand mountain region is related to the tectonic zone of the sanandaj-sirjan region and the area dominant neo-tectonic regime appears to be compressional-extensional type. one of the identification tools to find out th...

baneh pluton is located in northwest of kordestan province and sanandaj-sirjan zone. this body has been injected into low-grade metamorphic rocks in cretaceous and so it is attributed to upper cretaceous-paleocene. this complex is composed of three distinct intrusive phases. these phases are diorite, biotite-granite and garnet-bearing granite. diorites is the first constituent unit that is intr...

almabulage complex is located in the north of asadabad city, northwestern hamedan province, in sanandaj-sirjan structural zone. the complex includes several types of low-grade metamorphosed rocks with various protoliths as well as two intrusion having different chemical compositions of synogranite and gabbro. the synogranite intrusion rock has perthite and granophyric co-growths textures and au...

zafarabad iron deposit is located northwest of divandareh, in the northern margin of sanandaj-sirjan plutonic-metamorphic zone. the deposit is in lentoid to tubular shape, within a shear zone and occrrued in host rocks of calc-schist and limestone. magnetite with massive, cataclastic and replacement textures are the main phases, while pyrite and other sulfide minerals are found. major and trace...

the subduction of the northern part of the tethys is documented by arc magmatism from upper triassic to lower eocene crosscutting the sanandaj-sirjan zone and from upper eocene to plio-quaternary in the urumieh-dokhtar magmatic zone, situated north of the ssz. neyriz ophiolite is part of middle eatern neo-tethyan ocean of mesozoic that geographically is related to ophiolites of nw-se iran, alon...

Background & Aim: Since traditional knowledge is base of producing new herbals and other natural products, and old people of ancient cities know about characteristics of such herbals, therefore, death of such people will gradually causes demolishing of their knowledge about herbals. Therefore, it seems it is necessary to register and save such information. The goal of this research is to study ...
