FE SKARN MINERALIZATION AT THE LAJANEH DEPOSIT, NORTHEASTERN OF IRAN
Abstract
Lajaneh Fe skarn deposit is located in so uth of Shahrood City, North East of Iran. Mineralization is occurred as massive, veins and breccias in the c ontact of the dioritic intrusion with limestone. The dioritic intrusions in Lajaneh Fe skarn deposit display calc alkaline and metaluninous nature with I type characteristic. Tectonic setting discrimination diagrams show that dioritic intrusions in Lajaneh deposit belongs to volcanic arc granitoids (VAG). Negative anomalies of HFS elements like Nb, Ti, Ta and P and positive anomalies of K and Pb show a volcanic continent arc related to subduction. SiO 2 content of intrusive rocks in Laja neh deposit coincide with pluton rocks related to worldwide Fe skarn mineralization. But major oxide content of Al 2O3, TiO2, MgO, P 2O5 of dioritic intrusions of Laja neh deposit coincide with pluton composition related to Cu and Fe skarns mi neralization. The content of trace elements like V, Cr and Ni in Lajaneh deposit is similar to pluton composition of worldwide Fe skarn deposits.
