Abstract The Xiangdong W(-Sn) deposit is hosted in the Dengfuxian multiphase granites (biotite, two-mica, and muscovite granites) within Nanling Range metallogenic belt south China. Previous studies suggested that mineralization related to Late Jurassic two-mica granite, whereas recently W-Sn–bearing quartz veins have also been identified granite. We present new cassiterite zircon U-Pb ages constrain timing of W-Sn granitic magmatism. Our laser ablation-inductively coupled plasma-mass...

Tungsten and tin are important strategic critical mineral resources, as well one of China’s most abundant resources. Their distribution is mainly concentrated in the South China block, followed by Kunlun-Qilian-Qinling-Dabie orogenic belt, Tianshan-Xingmeng Tibet-Sanjiang belt. The tungsten resources Nanling tungsten-tin metallogenic northern Jiangxi-southern Anhui Youjiang-Guibei southeast coastal formation deposits spans a large period time, from Proterozoic to Cenozoic, but Mesozoic...

Sphalerite is a commonly occurring mineral in natural systems and prominent indicator used resource exploration. Its chemistry associated assemblages are both controlled by the physicochemical conditions of local environment, such as temperature sulfur fugacity. Accordingly, sphalerite nature minerals provide valuable clues about classification deposits their environment formation. Nevertheless, exclusive reliance on trace-element for deposit has its limitations given multitude factors (For...

Elucidating the causal relationship between parent granite and pegmatite tracing magmatic-hydrothermal evolution rare metal mineralization are intriguing scientific issues that remain unsolved. The Renli-Chuanziyuan granite-pegmatite field, hosted in adjacent to Mufushan batholith, represents a significant ore district southern China. field reveals well-defined regional zonation, encompassing biotite, two-mica, muscovite monzogranites at core, which transition outward microcline...

<title>Abstract</title> The search for alternatives to traditional fossil fuels has become a global priority, with lithium-ion batteries emerging as primary substitute conventional energy sources. importance of lithium increased significantly due the rapid development new vehicles, spodumene (LiAlSi₂O₆) being principal economic mineral extraction. Spodumene is predominantly found in pegmatites, despite that not all pegmatites are enriched spodumene. Spodumene-bearing...

The Nanling Range in South China is endowed with abundant Jurassic W–Sn and Cu skarn deposits; however, the ore-forming age process of these deposits lack adequate comparative studies. Huangshaping deposit coincidently develops both mineralization systems, providing a good window to address issues. Multiple generations hydrothermal scheelite were identified at Huangshaping, including SchA-1, SchA-2, SchA-3 system, SchB-1, SchB-2, SchB-3 system. Scheelite two systems has similar textural...

Abstract The Jiangnan orogen, one of the largest gold-producing areas in China, has experienced multiple orogenic events with complex structural overprinting that is marked by stages magmatism, deformation, metamorphism, and gold mineralization. Different have been recognized Neoproterozoic, mid-Paleozoic, Triassic, Early Cretaceous, reflecting collisions intracontinental episodes. age deposition however, poorly constrained owing to absence suitable dating minerals. Field studies orogen...

Abstract Rare metals including Lithium (Li), Beryllium (Be), Rubidium (Rb), Cesium (Cs), Zirconium (Zr), Hafnium (Hf), Niobium (Nb), Tantalum (Ta), Tungsten (W) and Tin (Sn) are important critical mineral resources. In China, rare metal deposits spatially distributed mainly in the Altay Southern Great Xingán Range regions Central Asian orogenic belt; Middle Qilian, South Qinling East mountains Qilian–Qinling–Dabie Western Sichuan Bailongshan–Dahongliutan Kunlun–Songpan–Garze belt,...

Numerous large deposits are formed by multiple mineralization events, however, how to identify superimposed events is poorly understood. The Xiangdong deposit a quartz vein-hosted W–Sn within the Dengfuxian composite granite in South China. Previous studies have suggested that there two discrete deposit, whereas ore-forming conditions and processes of still unclear. To address these ambiguities, this contribution characterized microtextures, trace-element chemistry, geochronology cassiterite...

The Huayuan orefield in the SW Yangtze Block (SW China) is a world-class Pb-Zn orefield, with over 20 million tonnes (Mt) metal reserve. However, ore fluid source and evolution remain controversial. This study determined major trace element compositions of newly-identified apatite from ores, using electron microprobe analysis (EMPA) laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). samples are hydrothermal origin, have high CaO (52.57–57.15 wt%), P 2 O 5 (39.26–42.88...

The Jiangnan Orogen is China's third largest gold province, and has undergone complex orogenic processes tectonic overprinting, forming multistage magmatism, deformation, metamorphism, mineralization. Our field studies indicate that the Tuanshanbei ores (central Orogen) have two generations of auriferous quartz-ankerite-pyrite-arsenopyrite veins (Q2 Q3), with latter containing abundant ankerite base metal sulfides. Both Q2 Q3 are younger than emplacement granodiorite vein-ore host, cut by...

Abstract Li-Cs-Ta (LCT ) rare-element pegmatites occur as late-stage and highly fractionated bodies at the margins of regionally zoned granite pegmatite fields. The evolution granitic system, including its rare-metal metallogeny, is often difficult to determine due complex textures involving variable crystal size a heterogeneous chemical composition. Renli-Chuanziyuan field (South China) displays well-developed regional zonation sequence, core biotite-, two-mica- muscovite monzogranites...

The Koka gold deposit is located in the Elababu shear zone between Nakfa terrane and Adobha Abiy terrane, NW Eritrea. Based on a paragenetic study, two main stages of mineralization were identified deposit: (1) an early stage pyrite–chalcopyrite–sphalerite–galena–gold–quartz vein; (2) second pyrite–quartz veins. NaCl-aqueous inclusions, CO2-rich three-phase CO2–H2O inclusions occur quartz veins at Koka. ore-bearing formed 268 °C from NaCl–CO2–H2O(–CH4) fluids averaging 5 wt% NaCl eq....
