The level of the Tethys Sea increased several times during deposition Mesozoic to Cenozoic sediments in Kuqa Basin Tarim Block. basin contains Paleogene Neogene units containing evaporite-rich layers, which are favourable sources for economic concentration potash (K-rich salt). However, basin's geology is poorly understood, lacking knowledge source brine, paleo-water temperatures, and degree evaporation. As a result, exploration mineralisation has been limited. This study documents...
Fluorite and lithium have become extremely important minerals globally. The newly discovered medium-to-large-scale Pingqiao fluorite-lithium deposit in the southwest Yangtze Block contains a rare mineral system with fluorite associations. This unique provides an excellent example for study of origin formation processes system. ore bodies mining area are hosted silicified limestone late Carboniferous Nandan Formation, lithium-bearing occur claystone micrite early Permian Longyin Formation....
In southwest China, claystone layers occur in the lower part of late Permian Xuanwei Formation, immediately overlying Emeishan flood basalts. The lowermost are characterised by high contents rare earth elements (REEs; 1100–16,000 ppm, average 2700 ppm), indicating a new type REE deposit. However, origin this deposit and enrichment mechanisms unclear. We collected samples from 10 sections including REE-rich claystones, siltstones, iron tuff. Detrital zircons gave U–Pb ages 275–245 Ma, εHf(t)...
The Xuanwei Formation’s claystones in the Dian-Qian District of Southwest China are rich rare-earth elements (REEs), suggesting their potential as a source medium and heavy rare earths. However, REE content these rocks is lower than other types deposits, interrelationship among clay minerals intricate. There no direct evidence indicating mineralization REEs, limiting beneficiation extraction. objective this study characterization distribution District. sedimentary district mainly composed...
Lithium (Li) stands as a critical mineral resource, finding applications across various industries such new energy, medicine, and optoelectronics (Bowell et al., 2020). Fluorite emerges strategic mineral, playing pivotal role significant non-metal resource in countries (Kesler 2012). Recently, discoveries of fluorite lithium have been made within the Early Permian strata Liuzhi area southwestern Yangtze Block, China, with reserves reaching large scale (fluorite > 400 Kt; 100 Kt). This...
Abstract Luku alkali syenite is distributed throughout the southern end of Hongge basic‐ultrabasic intrusion in Panzhihua, Sichuan, SW China. Using LA‐ICP‐MS, yielded a zircon U‐Pb age 264.5 ± 1.6 Ma, concordant with ages E'meishan large igneous province (260 Ma). The displayed silica‐saturated, Al‐adequate and alkali‐rich signatures, SiO 2 62.07%–64.04%, Al O 3 16.26%–16.79% Na + K 9.17%–9.91% (averaging 9.31%). rock falls into alkaline zone on ‐A.R. diagram, as well potassium O‐Na...
摘要: 贵州威宁地区宣威组底部稀土含矿岩系的成因类型一直有较大争议.在野外实地调查的基础上，运用矿物学、岩相古地理与地球化学等手段进行了系统性研究.结果显示，区内二叠系宣威组底部稀土含矿岩系广泛分布，连续性好，含矿段厚度为2~16 m，并伴生有铌、锆、镓等元素；稀土氧化物平均品位0.15%，最高可达1.60%.主量、微量和稀土元素分析表明威宁地区稀土含矿岩系中含有来自玄武岩及火山灰的典型矿物，稀土配分模式与玄武岩相比具有继承性，研究区化学风化作用较强、成分成熟度较高代表其经过长距离搬运，遭受了改造；峨眉山玄武岩为该稀土层提供了主要物质来源，稀土层受源岩成分的控制，经历了沉积分选及再循环作用，还遭受了来自上地壳的中酸性岩浆物质源区的混染.其成因机制可能为在晚二叠世炎热、潮湿、强风化的环境中，玄武岩经过风化剥蚀后，搬运至沉积基底低洼处的三角洲平原亚相中的洪泛平原微相环境，与火山灰一同沉积沉淀，在风化和淋滤作用下稀土等元素以离子形式被解析出来，从而被吸附性强的高岭石等黏土矿物吸附于表面，或进入矿物晶格，形成富稀土层. 关键词: 威宁 / 稀土 沉积型 岩相古地理 成矿模式 成因机制
