Abstract ：
The Huangtian tungsten deposit is a recently discovered large-scale scheelite deposit on the northern edge of the Laojunshan polymetallic mineralization area, in Southeast Yunnan province. Previous research has investigated the geological characteristics of the deposit and the evolution of mineralization fluids. However, the absence of a precise determination of its mineralization age and the contentious origin of its mineralization and materials have impeded the academic community's comprehensive comprehension of its mineralization mechanism. To determine this problem, this article conducted in-situ U-Pb dating and in-situ Sr isotope composition on main mineralization stage I scheelite based on detailed drilling core catalogs and mineral microstructure analyses. The results show that the scheelite formed (64.6 ±3.7) Ma (re =35, MSWD =1.6), reflecting that the mineralization occurred in the early Paleocene. When considered in conjunction with the geological background of the mine area, it is hypothesized that the mineralization is closely related to the deep, concealed granite body in the southern part of the mine section. The Sr/Sr values (0.720, 25-0.728, 40) of the Huangtian scheel-ite are significantly higher than those of the continental lithospheric mantle, indicating a crustal source. The initial Sr isotope ratios of the huangtian scheelite and the laojunshan granite are consistent, suggesting that they may have originated from a common hydrothermal system (long-lived magma chamber). The elevated concentration of Ca in Huangtian scheelite is primarily due to the sericitization of plagioclase in the granodiorite. The W element in Huangtian scheelite originates from the granodiorite by orthomagmatic model. This study defines the metallogenic era of tungsten deposits in Huangtian and traces the source of their mineralized materials. These findings lay a foundation for a deeper understanding of the metallogenic mechanisms and enrich our knowledge of the polymetallic metallogenic belt in Southeast Yunnan. Ultimately, this provides a theoretical basis for further prospecting in the region. © 2025 China University of Geosciences. All rights reserved.

Abstract ：
云南文山州小洞锑矿床处于滇东南锑矿带,矿体赋存于寒武系中统田蓬组下段硅质岩中.前人认为其属于变质改造的热水沉积型锑矿床,但关于该矿床的成岩成矿机制和矿床成因类型等问题仍有争议.对赋矿围岩硅质岩的主微量分析显示,w(SiO2)为 84.70%～97.11%(均值 92.19%),w(Al2O3)为0.63%～6.08%(均值 3.56%),ΣREE为(20.43～77.54)×10-6,稀土配分曲线右倾,δEu值为0.66～1.57(均值 0.88),δCe值为 0.95～1.15(均值 1.07),形成于大陆边缘的非热水沉积环境,成分受陆源输入的控制.辉锑矿 LA-ICP-MS分析揭示了其微量元素的主要耦合替代机制为 2Sb3+↔As3++(Cu++Pb2+).辉锑矿的S同位素分析显示δ34S值变化范围较窄(0.42‰～4.91‰),暗示成矿物质来源于岩浆,成矿热液可能与老君山岩体活动相关,或者为深部隐伏岩体带来的热液.综合分析认为,小洞锑矿床的赋矿围岩与热水沉积无关,成矿物质主要来源于岩浆热液.岩浆活动后期的含矿热液流体沿断裂带运移,在层间虚脱带富集成矿,属于受断裂控制的热液型锑矿床.

Abstract ：
荒田钨矿床位于滇东南老君山多金属成矿区北缘，是近年来新发现的一处大型白钨矿床。尽管前人已对该矿床的地质特征及成矿流体演化进行了初步研究，但其成矿时代的精细厘定仍显不足，成矿物质来源也存在争议，这在一定程度上限制了学界对其成矿机制的深入认识。基于详细的钻孔岩心记录和矿物显微组构研究，本文针对荒田钨矿床主成矿期I阶段的白钨矿进行了原位U-Pb定年和原位Sr同位素组成分析。结果显示，荒田白钨矿U-Pb年龄为（64.6±3.7 Ma）(n=35,MSWD=1.6),反映出成矿作用发生在古新世初期。结合矿区地质背景，推测成矿作用与矿段南段的深部隐伏花岗岩体密切相关。荒田白钨矿

福建永泰百漈沟地质公园内地质遗迹类型丰富,其中保存较完整的古火山(有古火山口、火山断裂带和各种火山岩石)是中国东部白垩纪时代火山的典型代表,该公园是认识和研究古火山的天然博物馆. 百漈沟古火山属于复合型火山锥,是由火山喷溢与爆发活动交替进行形成的、由喷溢相流纹岩和爆发相火山碎屑岩互层产出的火山机构,爆发相向火山外围减薄,喷溢相向火山外围增厚.火山活动结束后,由于底部岩浆房空虚,通常会造成火山机构坍塌,形成环状断裂及以火山口为中心的放射性断裂带.百漈沟景区即沿着该火山机构其中一条北东向的放射性断裂带展布.

Abstract ：
The mafic enclaves from Mesozoic intermediate-acid magmatic rocks, widely developed along Fujian coast, are considered to be the results of large-scale crust-mantle interaction and magma mixing. In this paper, petrography, mineralogy, and geochemistry of granites and mafic microgranular enclaves (MMEs) in Langqi Island are studied to provide new information for tracing crust-mantle interaction. The zircon U-Pb dating results show that the Langqi rocks were formed at similar to 101 Ma, which are metaluminous, enriched in silica and high-K calc-alkaline I-type granites. The enclaves have a typical magmatic structure, which is characterized by magma mixing between high-temperature basic magma and low-temperature acidic magma through injecting. The enclaves and host granites show a tendency to mixed major and trace elements, displaying a clear-cut contact relationship, which is indicative of coeval magmatism. The genesis of Langqi rocks is related to the extensional setting caused by the subduction of Paleo-Pacific Plate, and they are the results of mixing of subduction-related metasomatized mantle-derived mafic and induced crustal-melted granitic magma originating from partial melting of the crustal material.

Abstract ：
Many lamprophyre dykes occurring in north Guangxi province are probably the source rock for proximal diamond placer deposit, but their formation age has long been a pending geological issue. This study shows that phlogopites (phenocryst and matrix) in lamproite in the Rongshui area have a 40Ar-39Ar cooling age of 203~204 Ma, indicating that they formed in late Triassic. Analytical results show that the dykes are characterized by SiO2 content of 55.68%~56.85%, high K (K2O/Na2O=1.87~3.06) and high Mg# (71.90~73.20), enrichment of LREE and relative depletion of HREE with distinct differentiation between LREE and HREE, slightly Eu anomaly, enrichment of large ion lithophile elements (LILE) and depletion of high field strength elements (HFSE), geochemically suggesting that the dykes sourced from the enriched lithospheric mantle metasomatized by subduction-related fluids. This study shows that the Mesozoic lithospheric mantle under the southwestern margin of the Yangtze Carton is the an enriched mantle which experienced metasomatization of subduction fluid and thinning event due to lithospheric extension in the late Triassic, and its formation was probably related to the NW-trending subduction of the paleo-Pacific plate. © 2019, Science Press.

桂北地区发育较多的钾镁煌斑岩脉,可能为该区近源金刚石重砂矿的母岩,对于其形成时代一直是长期争议悬而未决的重要地质问题.本文研究表明,融水地区金云钾镁煌斑岩的金云母(斑晶、基质)40Ar-39 Ar冷却封闭年龄为203～204 Ma,表明其形成于晚三叠世.岩石SiO2为55.68％～56.85％,高钾(K2O/Na20=1.87～3.06)、高Mg# (71.90～73.20)、轻稀土富集、重稀土相对亏损,轻重稀土分异明显,Eu略亏损,富集大离子亲石元素,亏损高场强元素,地球化学特征表明其来源于俯冲流体交代的富集地幔特征.上述研究表明,扬子克拉通东南缘桂北地区中生代岩石圈地幔为经历俯冲流体交代的富集地幔,并于晚三叠世经历了重要的岩石圈伸展减薄构造事件,其形成可能与古太平洋板块平板式俯冲有关.
