Abstract

Abstract

To understand the electrical structure in Narusongduo ore concentration district in the Tibetan Plateau and its constraints on mineralization, the magnetotellurics data in the district were carefully processed and analyzed, obtaining a reliable 2-D electrical model. The study shows that there are some conductors at depths of about 40-50 km, 20-30 km and 10 km, which may be resulted from the partial melting and aqueous fluids. As the deposits in the district belong to the magmatic-hydrothermal type, and the upwelling deep-seated magma played an important role in the mineralization, the crustal conductors may offer constraints to the ore-related magma reservoirs, and connecting these conductors also may represent the ancient ascending channels. The electrical structure indicates the relationship between the crustal conductors and the regional metallogenic dynamics in our study. The ascending ore-bearing magma also may migrate to the Pb-Zn and Fe-Cu locations by the local hidden structures, and subsequently evolved into the ore body.
