ABSTRACT In this article, a systematic LA‐ICP‐MS zircon U–Pb geochronology study was carried out on the Xishan pluton in Nanling Range. The results show that formation ages of granitic porphyroclastic lava, medium‐fine‐grained porphyritic granite, and dacite are 154.0 ± 1.2–156.1 2.0, 153.2 0.9–157.3 3.2, 151.2 3.1 Ma, which determined to be early Yanshanian. Geochemical data characterised by rich silicone‐alkali poor calcium–magnesium with K 2 O/Na O ratios 1.65–2.22, Al 3 1.00–1.14,...
The Jiepailing deposit in southern Hunan is a typical large to super-large polymetallic tin enriched beryllium and other rare metals. To enhance the understanding of mineralization processes deposit, detailed mineralogical, situ geochemical, sulfur isotopic analyses were conducted on pyrite closely associated with tin–polymetallic mineralization. Five types have been identified deposit: (1) euhedral subhedral medium- coarse-grained (PyI) tungsten–tin ore; anhedral fine-grained (PyII)...
Greisenization is an important stage of Sn-W mineralization, its mechanism Sn enrichment and deposition remains debated (e.g., boiling, cooling, fluid-rock interaction, fluid mixing). In this study, we performed detailed petrography geochemical studies different types tourmalines in the Baishaziling greisen-type tin deposit, aiming to investigate magmatic-fluid evolution ore-forming processes. Major elements show that almost all have high Fe/(Fe + Mg) ratios with affinity alkali group schorl...
The Tengshan'ao Sn deposit, located at the Dayishan ore field, Nanling Range, is one of recently explored deposits in this region. In study, LA-MC-ICP-MS cassiterite U–Pb and muscovite 40Ar-39Ar isotopic dating analyses for altered granite-type ores yielded ages 156.7 ± 4.3 Ma 151.1 1.5 Ma, respectively. These are consistent to zircon age fine-grained two-mica monzogranite (158.2 1.6 Ma), indicating a coeval magmatism mineralization Late Jurassic deposit. It further demonstrated that...
Abstract Tourmaline occurs widely within Dayishan ore field, Nanling Range, and is associated with magmatic-hydrothermal rare metal mineralization. Four types of tourmaline are recognized: (1) tour-maline in coarse-grained monzogranite (Tur-G1); (2) medium–fine-grained (Tur-G2); (3) aggregates muscovite greisen (Tur-Gr), showing a yellow core (Tur-Gry) blue rim (Tur-Grb); (4) quartz-vein-hosted (Tur-V). In this study, we performed systematic investigations situ boron isotopic elemental...
The Tongmukeng tin deposit is situated in the Yunshan area of Jiangnan orogenic belt South China. ore body primarily distributed along joints and fractures within granites, with some occurrences found contact zones between granite surrounding rocks. Two types fine- coarse-grained granites related to body, were comprehensively investigated using whole-rock geochemistry, zircon cassiterite U-Pb dating, Lu-Hf isotopes, as well oxygen isotopes. ages two are constrained ∼ 127 Ma, which consistent...
The Maozaishan Sn deposit, located south of the Dayishan ore field in Nanling Range, is a newly explored greisen-type deposit. Two muscovite samples from tin-bearing ores yielded 40Ar/39Ar plateau ages 154.7 ± 1.1 Ma (Mean standard weighted deviation (MSWD) = 0.48) and 152.6 0.7 (MSWD 0.25), respectively. Zircon U–Pb dating result fine-grained biotite monzogranite mining area shows that these zircon grains can be subdivided into two populations, with 154.2 2.0 0.51) 159.6 1.9 0.09),...
The Wujiaping Sn deposit is located at the northern Dayishan ore field, South China, whose veins are mainly hosted in pluton. LA–ICP–MS zircon U–Pb dating for medium-fine grained- and medium-coarse grained-biotite monzogranite of pluton yields emplacement ages 154.5 ± 1.6 Ma (MSWD = 2.0) 155.5 0.5 1.9), respectively, which consistent with muscovite 40Ar-39Ar plateau age 150.4 0.9 quartz vein type veins. It indicated that mineralization related to Late Jurassic granitic magmatism. These...
Abstract The Qieganbulake deposit associated with a mafic–ultramafic–carbonatite complex in the Kuluketage block is not only world’s second-largest vermiculite deposit, but also medium-size carbonatite-related phosphate deposit. Field observations, radiometric dating results and Sr–Nd–Hf isotopes reveal that parental magmas of carbonatite mafic–ultramafic rocks are cogenetic formed synchronously at c . 810 Ma. Geochemical characteristics Sr–Nd–Hf–S (( 87 Sr/ 86 Sr) i = 0.70581–0.70710; ϵ Nd...
The formation and evolution of the ancient continental crust are crucial issues in solid-earth geology which commonly associated with global tectonic events economically valuable magmatic-hydrothermal ore deposits. Cathaysia Block, one continents Southeast Asia, can be subdivided into two parts: West Block East Block. Unlike no Precambrian rocks exposed constraining further understanding this block. In study, a total four hundred thirty-three zircon U-Pb dating analyses eighteen Lu-Hf...
The determination of deposit age is fundamental in economic geology, while the result often disappointing because difficulties selection suitable minerals. In this study, on base detailed field investigation, we successfully combined muscovite 40Ar-39Ar dating and cassiterite LA-ICP-MS U-Pb Aotou tin deposit, Jiangxi province, South China. 40Ar–39Ar plateau ages (228.7 ± 1.5 Ma) lower intercept (227.4 6.9 are consistent, accurately defined that was formed during late Indosinian. With gradual...
