Abstract

Both SANGAN and TANNURJEH magnetite deposits are Iron-oxides type. Geochemistry and petrography of SOURCE ROCKS at TANNURJEH and SANGAN were studied in detail. The SOURCE ROCKS at SANGAN are compused of quartz hornblende alkali syenite porphyry and quartz biotite-hornblende alkali syenite porphyry; while The SOURCE ROCKS at TANNURJEH varies between hornblende quartz diorite porphyry and hornblende granodiorite porphyry. The AU content of SANGAN deposit is up to 32 ppb, while TANNURJEH contains up to 700 ppb AU. Based on major oxides analyses, the SOURCE ROCKS at SANGAN is ultra-potassic (K2O is 8.5 to 13%), but in TANNURJEH the K2O is lower than 3.5%. The MgO, TFeO, and CaO content of TANNURJEH SOURCE ROCKS is higher, therefore the rocks are slightly mafic in comparison with SANGAN SOURCE ROCKS. The content of HFSE elements such as Cu, Ni, Co, Cr, V are higher in SANGAN SOURCE ROCKS and the LILE elements such as Th, Zr, Ba, Rb are higher in TANNURJEH SOURCE ROCKS. The La and Ce content of TANNURJEH is higher. At TANNURJEH the Sr and Zn content is higher while at SANGAN Nb and Y is higher. The SOURCE ROCKS for IOCG deposits in Chile, coastal belt of Peru, and kirona areain Sweden are high to medium K-content, and alkaline to calc-alkaline diorite-monzonite-granodiorite; there fore the SOURCE ROCKS at TANNURJEH have very ligh similarity in composition to these rocks.
