| Abstract/Notes | The newly discovered Xiaohongshilazi deposit located in Panshi City, central Jilin Province, NE China, is a medium-scale PbāZnā(Ag) deposit. The PbāZnā(Ag) orebodies are divided into layered and vein-type orebodies, which have different ore geneses. The layered PbāZn orebodies are mainly hosted within and spatially controlled by the volcanic rocks. To constrain the age and tectonic setting of the layered PbāZn mineralization, we completed laser-ablationāICPāMS zircon UāPb dating and whole-rock major and trace element analyses of the ore-bearing volcanic rocks. The dacite samples were confirmed as belonging to the Daheshen Formation and were the main ore-bearing volcanic rocks for the layered orebodies. They yielded concordia UāPb ages of 278.1 Ā± 1.8 Ma and 278.3 Ā± 1.8 Ma, respectively, indicating that the volcanic rocks from the Daheshen Formation and related layered PbāZn mineralization were formed in the early Permian. The andesite and rhyolite located above the layered orebodies yielded concordia UāPb ages of 225.0 Ā± 1.1 Ma, 225.3 Ā± 1.5 Ma, and 224.7 Ā± 1.2 Ma, respectively; these substances are considered to be of the Sihetun Formation and were first reported in the area. The dacite samples associated with layered PbāZn mineralization were high in SiO2 (62.54ā65.02 wt.%), enriched in LREEs and LILEs (e.g., Rb, Ba, and K), and showed depletion in HFSEs (e.g., P and Ti). It showed slightly negative Eu anomalies (Ī“Eu = 0.60ā0.65) and negative Nb anomalies, with Th/Nb (1.12ā1.21) and La/Nb (2.8ā4.7) ratios, presenting subduction-related arc magma affinity formed in an active continental margin setting. In agreement with previous studies on zircon Hf isotopes (ĪµHf (t) = + 0.23Ā + 10.60) of the volcanic rocks from the Daheshen Formation, we infer that they were derived from the partial melting of the depleted lower crust. In conclusion, mineralization characteristics, geochronological data, geochemical features, and regional tectonic evolution suggest that two PbāZnā(Ag) mineralization stages from the Xiaohongshilazi deposit occurred: the layered VMS-type PbāZn mineralization associated with the marine volcanic rocks from the early Permian Daheshen Formation, which was induced by the subduction of the Paleo-Asian oceanic plate beneath the northern margin of the North China Craton, and the vein-type PbāZnā(Ag) mineralization caused by the subduction of the Paleo-Pacific Plate in the early Jurassic. Considering this, along with the mineralization characteristics of the same-type polymetallic deposits in this region, we propose that the early Permian marine volcanic rocks have great prospecting potential for the VMS-type PbāZn polymetallic deposits. |
