Tourmaline is a common borosilicate mineral in granite and pegmatite， and it is also an important carrier to record the physicochemical evolution information of magmas. However， the genetic relationship between pegmatite-type rare metal mineralization potential and tourmaline-bearing pegmatites is not clear， and the tourmaline geochemical indication of the mineralization type of rare metals needs to be supplemented. In the middle Altun region， extensive tourmaline-bearing pegmatite dykes are prevalent within and surrounding the Tugeman complex. In this paper， the petrology and geochemical characteristics of tourmaline within the pegmatite of the Tugeman Be-Li deposit have been comprehensively analyzed. The research delves into the genetic evolution and metallogenic potential of the pegmatite， emphasizing the indicative role of tourmaline geochemistry in discerning mineralization types in the Tugeman Be-Li deposit. Major and trace element analysis of tourmaline reveals varying contents of FeO （9.37 wt.%–17.10 wt.%）， Al2O3（28.64 wt.%–35.22% wt.%）， and MgO （0.13 wt.%–2.47 wt.%） in the Tugeman Be–Li pegmatite. Li， Zn， and Sn contents range from 204 ppm to 1 590 ppm， 1 143 ppm to 4 089 ppm， and 74 ppm to 396 ppm， respectively. The tourmaline analyzed in this study is magmatic origin and belongs to schorl series， exhibits substitution relationships， including (Na， Fe2+)(X□， Al)-1， (Fe2+， Fe3+)（Mg， Al）-1， (Al，X□)(R2+， Na)-1，（Na， Mg）(X□， Al)-1andX□NaR2+-1. The trace element data of tourmaline show that lithium has four enrichment stages in different mineral crystallization phases. Notably， the tendency of tourmaline in the Tugeman Be-Li pegmatite to evolve towards elbaite implies a magmatic evolution sequence from low to high， transitioning through microcline-albite pegmatite， muscovite-microcline-albite pegmatite， albite pegmatite， and microcline pegmatite. Furthermore， we also propose that the Sc content in schorl can serve as an indicator of pegmatite mineralization typ

Source and Enrichment Mechanism of Lithium in the Triassic Argillaceous Marine Sediments from Huangjinkou, Sichuan, China

引用

Acta Geologica Sinica(English Edition) 2022年第2期96卷 536-545页

作者： QIN Yan WANG Denghong ZHAO Yue YU Yang GAO Juanqin YU Feng ZHONG Jiaai LIU Zhu Key Laboratory of Metallogeny and mineral Assessment Ministry of Natural ResourcesInstitute of Mineral ResourcesChinese Academy of Geological SciencesBeijing 100037China School of Earth Science and resources China University of GeosciencesBeijing 100083China The 405 geological team Sichuan Province Geology and Mineral Exploration and Development BureauDujiangyanSichuan 611830China

In the Triassic marine sediments, an obvious enrichment of lithium has been found. The source and enrichment mechanism of lithium is unknown. Here, we report trace and rare earth element and isotope analyses for Triassic sedimentary samples from core ZK601, recovered from the Huangjinkou anticline in the Xuanhan basin. Lithium concentrations from the Leikoupo and Jialingjiang formations are much higher than the average concentrations in the crust of eastern China and in other marine sediments. Lithium concentrations are highest at depths of 3300–3360 m(in argillaceous marine sediments), and Li is positively correlated with Rb, Ga, Zr, Nb and other trace elements. The range of δ^(7)Li values in our samples is consistent with that in other Triassic marine carbonate rocks. Lithium concentrations and isotope ratios are negatively correlated in the argillaceous dolomite samples at depths of 3300–3360 m. We compared the results in this study with trace and rare earth elements in the clay from Sichuan and Chongqing, and propose that the clay in the argillaceous marine evaporites from Huangjinkou formed via the hydrolysis of volcanic ash during Early–Middle Triassic volcanic eruptions into brine basins, during which clay adsorbed Li from the brine and formed Li-rich argillaceous dolomites. The addition and hydrolysis of volcanic ash in the evaporative brine is also related to the formation of a new type of polyhalite.

作者： YAN Jun HOU TianJie WANG AiGuo WANG DeEn ZHANG DingYuan WENG WangFei LIU JianMin LIU XiaoQiang LI QuanZhong School of Resource and Environmental Engineering Hefei University of TechnologyHefei 230009China Nanjing Institute of geology and mineral resources China Geological SurveyNanjing 210016China 332 geological team of bureau of geology and mineral resources exploration of anhui province Huangshan 245000China

Yanshanian magmatisms are intensive in the southern anhui province and can be divided into early(152–137 Ma)and late(136–122 Ma) stages. A Yanshanian granitic zone was found to crop out along Qingshan to Changgai areas in the Tunxi district in Field investigation which has a genetic link with molybdenum multiple metal mineralization. To be a representative syenitic granite in the southern anhui province, the Huangshan pluton has not been found so far to have any genetic link with mineralization. Zircon LA-ICP-MS dating indicate that the four granitic bodies from the Qingshan-Changgai zone have concurrent formed ages from 140±4 to 141±2 Ma, belonging to the Yanshanian early stage magmatism. However, the Huangshan granite is dated to be 129±2 Ma, belonging to the Yanshanian late stage magmatism. The Qingshan-Changgai granites show high SiO2 and K2 O contents, low P2O5 contents and middle Al2O3 contents and are high-K calc-alkaline series metaluminum I-type granite. These rocks are characterized by enrichments in the large ion lithophile elements and light rare earth elements(REE), depletions in the high field-strength elements, and middle degree negative anomalies of Eu, geochemical features of arc or continent crustal derived magma affinities. These rocks have 87Sr/86Sr(t) ratios from 0.7120 to 0.7125, εNd(t) values from.7.24 to.4.38 and zircon εHf(t) values of.4.4 to 6.7, similar to that of the coeval ore-bearing granodiorites in the southern anhui province. Integrated geochemical studies indicate that the Yanshanian ore-bearing granodiorites were formed by partial melting of the Meso-Neoproterozoic accreted thickened low crust. Meanwhile, the Qingshan-Changgai granites were formed through a AFC process of plagioclase+amphibole+Shangxi Group of magmas that formed the ore-bearing granodiorites. The Huangshan granites are characterized by high SiO2 and K2 O contents, moderate Al2O3 contents, seagull shape REE distributed pattern and distinct Eu negative abnormities. C

The Nage Cu-Pb deposit, a new found ore deposit in the southeast Guizhou province, southwest China, is located on the southwestern margin of the Jiangnan Orogenic Belt. Ore bodies are hosted in slate and phyllite of Neoproterozoic Jialu and Wuye Formations, and are structurally controlled by EW-trending fault. It contains Cu and Pb metals about 0.12 million tonnes with grades of 0.2 wt% to 3.4 wt% Cu and 1.1 wt% to 9.27 wt% Pb. Massive and disseminated Cu-Pb ores from the Nage deposit occur as either veinlets or disseminations in silicified rocks. The ore minerals include chalcopyrite, galena and pyrite, and gangue minerals are quartz, sericite and chlorite. The H-O isotopic compositions of quartz, S-Cu-Pb isotopic compositions of sulfide minerals, Pb isotopic compositions of whole rocks and ores have been analyzed to trace the sources of ore-forming fluids and metals for the Nage Cu-Pb deposit. The oSCUNBs values of chalcopyrite range from -0.09% to ＋0.33%0, similar to basic igneous rocks and chalcopyrite from magmatic deposits. J6SCUNBS values of chalcopyrite from the early, middle and final mineralization stages show an increasing trend due to 63Cu prior migrated in gas phase when fluids exsolution from magma, ja4ScDT values of sulfide minerals range from -2.7‰ to ＋2.8‰, similar to mantle-derived sulfur （0±3‰）. The positive correlation between J65CUNBs and ja4SCDT values of chalcopyrite indicates that a common source of copper metal and sulfur from magma. JDu2o- SMOW and JlSOH2O-SMOW values of water in fluid inclusions of quartz range from -60.7‰ to -44.4‰ and ＋7.9‰ to ＋9.0%0 （T=260℃）, respectively and fall in the field for magmatic and metamorphic waters, implicating that mixed sources for H20 in hydrothermal fluids. Ores and sulfide minerals have a small range of Pb isotopic compositions （208Pb/204pb=38.152 to 38.384, 207Pb/204Pb=15.656 to 17.708 and 206Pb/204Pb=17.991 to 18.049） that are close to orogenic belt and upper crust Pb evolution curve, and similar to

The Heyuan Fault, is one of the main NE-trending faults in the southernmost South China Block and is close to the northernmost South China Sea to the south. The fault features multi-stage deformation and controlled the formation of late Cretaceous to Cenozoic basins. Based on detailed field investigations and comprehensive geochronological research, including zircon U-Pb, Rb-Sr isochron, zircon U-Th-He dating, two episodic tectono-thermal events are recognized. The first occurred during ~79 Ma to 66 Ma, which is characterized by large-scale quartz-fluid emplacement. The other occurred at ~34 Ma, which features the eruption of a set of basalts. The two events show a changing on material source from siliceous hydrotherm to basalt magma, supporting obvious lithospheric thinning of the southernmost South China Block, which shed light on the geological evolution and the interaction mechanisms between the SCB and the northern South China Sea since the Late Cretaceous.
