Abstract The Dachang tin-dominant polymetallic district in western South China, hosts a total reserve of 110 Mt ore @ 1% Sn, 3–5% by-products of Zn, Pb, Sb, In and Cu, and 100 to 300 g/t Ag. Economic tin orebodies in the district mainly developed in Devonian limestone, black shale and siliceous rocks, as massive/stratiform and vein/stockwork mineralization. LA-ICP-MS U–Pb dating on seven cassiterite samples from the Tongkeng-Changpo and Gaofeng Sn–Zn–Pb deposits, and the Dafulou, Huile and Kangm...

Abstract Understanding the connection between the highly evolved intrusive and extrusive systems is essential to explore the evolution of high silicic magma systems, which plays an important role in discussions of planetary differentiation, the growth of continents, crustal evolution, and the formation of highly evolved magma associated Sn–W–Mo mineral systems. To discern differences between “fertile” and “non-fertile” igneous rocks associated with Sn–W–Mo mineralization and reveal the genetic l...

Garnet zonation provides an unparalleled record of the pressure-temperature-time-fluid evolution of metamorphic rocks. At extreme temperature conditions >900 °C, however, most elements preserve little zonation due to intracrystalline diffusional relaxation. Under these conditions, slowly diffusing trace elements including P, Na, and Ti have the best chance of recording metamorphic histories. Here we map dramatic zoning patterns of these elements in subducted high-pressure felsic granulite (Saxon...

Abstract Chemical diffusion of Nb and Ta under anhydrous, pO 2 -buffered conditions has been measured in natural titanite. The source of diffusants were mixtures of CaSiO 3 , TiO 2 , and Al 2 O 3 powders, with either Nb or Ta oxides added. Experiments were run in evacuated sealed silica glass ampoules with solid buffers (buffered at NNO). Rutherford Backscattering Spectrometry (RBS) was used to measure Nb and Ta concentration profiles. The following Arrhenius parameters were obtained for Nb and ...

Abstract Fe isotope compositions of bulk samples from Gaosong ore deposit in Gejiu district, SW China were investigated and an overall variation in δ 56 Fe values from − 0.33‰ to + 0.20‰ has been observed. In this study, the δ 56 Fe values of primary sulfide ores are lower than the oxidized ores, while the iron isotope compositions of gossan samples, which represent highest oxidation degree, are heavier than the oxidized ore samples. These data indicate that iron isotopes experienced fractionati...

Abstract The Nanling Range in South China hosts numerous W–Sn–rare metal deposits associated with several cycles of polygenetic granitic intrusions. In the Wangxianling area of the middle Nanling Range, igneous intrusions include the Wangxianling and Hehuaping granite plutons and more than 20 granite porphyry dykes. The Wangxianling pluton has a central phase of medium-grained tourmaline two-mica granite and a marginal phase of medium-grained tourmaline muscovite granite. The pluton hosts severa...

The Winton Formation provides an important snapshot of Australia's late Mesozoic terrestrial biota, boasting a vertebrate fauna that includes dinosaurs, crocodyliforms, aquatic squamates, turtles, lungfish and teleost fishes, and a flora that has previously been considered to include some of the world's earliest known flowering plants. Despite its significance, poor age control has thus far prevented precise regional and global correlations, limiting the depth of paleobiogeographic assessments. ...

The Gejiu tin-polymetallic deposits in the Western Cathaysia Block of South China comprise the world's largest primary tin district, with a total resource of approximately 300 million metric ton ores, at an average grade of 1 wt percent Sn. Tin polymetallic mineralization occurs in five deposits and has four ore types, i.e., greisen, skarn, stratabound cassiterite-sulfide (mostly oxidized) and vein type ore. In each deposit the orebodies typically occur in an extensive hydrothermal system center...

Abstract This study reports in-situ determination of major and trace element compositions of calcite and apatite, and U–Pb ages of apatite for carbonatites and associated okaites and ijolites from the Oka carbonatite complex (Canada). Both apatite and calcite are rare earth element (REE)-enriched (total REEs > 4 wt.%), with REE and SiO 2 contents that correlate positively in apatite. This result supports the previously proposed substitution scheme of REE 3+ + Si 4+ = Ca 2+ + P 5+ . With the exce...

Abstract Bromine and chlorine are important halogens for fluid source identification in the Earth's crust, but until recently we lacked routine analytical techniques to determine the concentration of these elements in situ on a micrometer scale in minerals and fluid inclusions. In this study, we evaluate the potential of in situ Cl and Br measurements by LA-ICP-MS through analysis of a range of scapolite grains with known Cl and Br concentrations. We assess the effects of varying spot sizes, var...

The large-scale Maoping W–Sn deposit in the Gannan metallogenic belt of the eastern Nanling Range, South China, spatially associated with the Maoping granite pluton, hosts total ore reserves of 103,000 t WO3 and 50,000 t Sn. Two different types of mineralization developed in this deposit: Upper quartz vein-type mineralization, mostly within the Cambrian metamorphosed sandstone and slate, and underneath greisen-type mineralization within the Maoping granite. Cassiterites from both types of minera...

The Xi’ao Cu-Sn polymetallic deposit is located in the inner alteration zone of the Laoka granite. The ore bodies extend to 400 m in the granite rock and primarily occur with fluorite and potassic alterations. Two cassiterite samples of altered rock-type ore and one tourmaline vein-type ore in the Xi’ao Cu-Sn polymetallic deposit yielded U-Pb ages of 83.3 ± 2.1 Ma, 84.9 ± 1.7 Ma, and 84.0 ± 5.6 Ma, respectively. The Raman spectrum peak values of A1g were shifted to a lower frequency, possibly du...
