Abstract

Abstract

The Pulang Cu deposit, located in the Gezan ore-concentrated area of the Sanjiang Tethyan belt, is the largest porphyry Cu-Mo polymetallic deposit formed during the Indosinian orogeny. The north section of the first mining area is a key resource area of the deposit, but its metallogenic characteristics are quite different from those of the first mining area. It remains unclear whether the first mining area and its northern section are products of the same genetic magmatic activity, limiting the in-depth exploration of its relationship with the mineralization of the first mining area and the general understanding of the metallogenic law. In this study, we present new Re-Os geochronology of molybdenite from this section, aiming to provide basic geological data for further exploration and evaluation of metallogenic regularity and resource prospects in the northern region, and to guide further exploration efforts. The molybdenite Re-Os data yield a weighted mean model age of (202.35±0.84)Ma and an isochron age of (200.7±9.2)Ma, slightly younger than the orebody in the first mining area. The mineralization in the No. Ⅰ composite intrusion in the south zone of Pulang spanned a long period (ca. 20 Myr), possibly related to multiple pulses of ore fluids, suggesting a high potential for undiscovered resources in the north section of the first mining area. The Re content of molybdenite ranges from 1.50×10^－4 to 4.45×10^－4, with an average of 2.64×10^－4, indicating a mantle-derived ore-forming materials. The tectonic setting for mineralization was the flat subduction of the Ganzi-Litang ocean beneath the Yidun arc in the southern Gezan area, which triggered partial melting of the oceanic crust and generated voluminous adakitic magmas and associated ore fluids.
