Petrology and geochemistry of intrusive body of iron deposit of Sarab-3, east of Takab-north west of Iran
The Sarab-3 intrusive bodyis located in the NW of Iran, in Sanandaj-Sirjan zone and in the east of Takab city. Based on field observations as well as petrographic features, the lithologic composition of intrusion (Miocene age) ranges within the diorite-leucodiorite, monzodiorite, quartz monzodiorite...

| description | The Sarab-3 intrusive bodyis located in the NW of Iran, in Sanandaj-Sirjan zone and in the east of Takab city. Based on field observations as well as petrographic features, the lithologic composition of intrusion (Miocene age) ranges within the diorite-leucodiorite, monzodiorite, quartz monzodiorite, granodiorite and granite. In terms of geochemical characteristics, the rocks studied, are I-type, with calc-alkaline affinity and meta-aluminous character. Enrichment of LILE (K, U, Sr, Ce, Th, Pb, Ba) and LREE relative to HFSE (Zr, Y, Ti, P, Nb) and HREE, low Ce / Pb and Nb / U ratios and high Ba / Nb reveal that the rocks under study were originated in an active continental margin subduction-related tectonic setting. The negative anomalies of Ti, Nb and P on the spider diagram also confirm this fact. Low ratios of (Na2O + K2O / (FeOt + MgO + TiO2) and (Al2O3 / FeOt + MgO + TiO2) along with low Rb/Sr concentration (< 0.6) propose that the Sarab-3 intrusive rock is derived from a meta-basaltic source. |
