辽东半岛白云金矿床的成因类型与成矿时代长期存在争议。为解决这一问题，研究人员通过黄铁矿Rb-Sr定年（218.6±0.4 Ma）、锆石U-Pb年代学（226–95 Ma）及Sr-Nd-Hf同位素分析，首次建立了该矿床的完整时空框架，揭示其为晚三叠世与岩浆活动相关的金矿床（IRGD），并提出了古扬子克拉通（YC）俯冲背景 ...

研究人员针对东昆仑造山带新发现的那仁郭勒（NRGL）岩浆镍铜硫化物矿点，通过系统的年代学（LA-ICP-MS U-Pb定年）、岩石学、全岩地球化学及Sr-Nd-Hf同位素分析，首次揭示了其形成时代（258.7±1.4 Ma）、源区性质（富集地幔受俯冲流体交代）及构造背景（安第斯型活动大陆边缘）。该研究填补了东昆仑 ...

Abstract Geochemical and Nd‐Sr‐O whole rock isotope data and Pb isotope data from leached feldspars for a suite of synorogenic (ca. 540 Ma) syenites and granites from the northern part of the ...

Researchers constructed the first largescale, semi-quantitative Sr-Nd isotope baseline for the vast Silk Road regions, and validated its application in plant-ash glass provenance.
