Special Issue Information

Dear Colleagues,

W-Sn deposits provide numerous resources valuable and critical to the world. In 2022, we organized the first Special Issue on “Mineralogy, Geochemistry and Geochronology of W-Sn Polymetallic Deposits”, which received significant attention from many scholars. The recent progresses on W-Sn deposits call for further concentrated discussion on their mineralization processes. At present, the study of W-Sn deposits mainly focuses on two aspects. First, the genesis of highly differentiated granites, including the determination of major/trace elements, Sr-Nd isotopes of rocks, and Hf-O isotopes of related accessory minerals (such as zircon and apatite). These studies provide a good method for understanding the tectonic background of the deposits, sources, and evolutionary processes of magmas, ore-forming factors (such as redox environment, water content, sulfur fugacity, temperature, and pressure conditions), and the close relationship between magmas and ores. Second, with the development of in situ analysis, the texture, trace elements, and isotopes (e.g., W, Sn, Sr, Mo, and B) of a variety of metal minerals (e.g., scheelite, cassiterite, wolframite, molybdenite, and tourmaline) as well as gangue minerals (e.g., quartz and mica) related to W-Sn mineralization have been studied, providing insights that help reveal the multi-stage mineralization processes. This Special Issue will continue to focus on recent advances in W-Sn polymetallic deposits research, including but not limited to topics such as magma sources and the evolutionary processes of mineralization-related granites, in situ analysis of W- and Sn-bearing minerals, fluid exsolution and mineral precipitation processes, and the geochemistry/geochronology of typical W-Sn polymetallic deposits worldwide.

The Jiulongnao W–Sn ore field in the eastern Nanling Range is characterized by large-scale early Yanshanian magmatic activity and W–Sn mineralization. In recent years, increasing attention has been given to the close relationship between Indosinian magmatic activity and Sn mineralization. The Aotou quartz vein-type Sn deposit is unique for only Sn mineralization without W during the Indosinian period. Seventeen thin-to-thick cassiterite–quartz veins are densely distributed in Ordovician metasandstone and slate, and these veins extend down to the top of the concealed granite. However, both the diagenetic age and the petrological characteristics of the concealed granite remain unclear. This contribution shows that the Aotou muscovite intrusion is a highly fractionated S-type pluton, characterized by a peraluminous, high-K composition, enrichment in LREEs, and depletion of Ba, Sr, Ti, and Eu. In this study, LA–ICP–MS zircon U–Pb dating of the concealed muscovite granite yields emplacement ages of 238.7 ± 1.0 Ma and 225.4 ± 0.9 Ma, indicating that at least two stages of magmatic intrusion occurred in the Triassic, with the diagenetic environment transitioning from a compressional setting to an extensional setting. The εHf(t) values during the two stages are −0.98 to −0.95 and −0.98 to −0.96, and the TDM2 values are 1.78–2.08 Ga and 1.78–2.06 Ga, indicating that two-stage magma was derived from the late Paleoproterozoic lower crustal materials. Comprehensive analysis reveals that the second stage of Indosinian magma intrusion (232–225 Ma) in the Jiulongnao ore field is closely related to Sn mineralization, and the northern Wenying pluton has good prospecting potential for quartz vein-type Sn(–W) deposits.

The Karamaili Granite Belt (KGB) in the southern margin of the Eastern Junggar is the most important tin metallogenic belt in the southwestern Central Asian Orogenic Belt. The plutons in the western part have a close genetic relationship with tin mineralization. The zircon U-Pb ages of the Kamusite, Laoyaquan, and Beilekuduke plutons are 315.1 ± 3.4 Ma, 313.6 ± 2.9 Ma, and 316.5 ± 4.6 Ma, respectively. The plutons have high silica (SiO2 = 75.53%–77.85%), potassium (K2O = 4.43%–5.42%), and alkalis (K2O + Na2O = 8.17%–8.90%) contents and low ferroan (Fe2O3T = 0.90%–1.48%), calcium, and magnesium contents and are classified as metaluminous–peraluminous, high-potassium, calc-alkaline iron granite. The rocks are enriched in Rb, Th, U, K, Pb, and Sn and strongly depleted in Ba, Sr, P, Eu, and Ti. They have strongly negative Eu anomalies (δEu = 0.01–0.05), 10,000 Ga/Al = 2.87–4.91 (>2.6), showing the geochemical characteristics of A-type granite. The zircon U/Pb ratios indicate that the above granites should be I- or A-type granite, which is generally formed under high-temperature (768–843 °C), low-pressure, and reducing magma conditions. The high Rb/Sr ratio (a mean of 48 > 1.2) and low K/Rb ratio (53.93–169.94) indicate that the tin-bearing plutons have undergone high differentiation. The positive whole-rock εNd(t) values (3.99–5.54) and the relatively young Nd T2DM model ages (616–455 Ma) suggest the magma is derived from partially melted juvenile crust, and the underplating of basic magma containing mantle materials that affected the source area. The results indicate the KGB was formed in the tectonic transition period in the late Carboniferous subduction post-collision environment. Orogenic compression influenced the tin-bearing plutons in the western part of the KGB, forming highly differentiated and reduced I, A-type transition granite. An extensional environment affected the plutons in the eastern sections, creating A-type granite with dark enclaves that suggest magma mixing with little evidence of tin mineralization. Full article
