隶属于美国科学促进会,最新IF:14.957 官方网址: https://www.science.org/journal/sciadv ,然而氟(F)和氯(Cl)在地幔深处的行为机制仍不清楚,imToken官网下载, 挥发分通过俯冲带的循环深刻塑造了地球的化学演化,imToken下载, implicating them as key agents of cratonic metasomatism. Our findings establish phengite as a critical carrier mediating postarc fluxes of F (1.7 1012 to 2.6 1012 grams per year) and Cl (0.52 1012 to 1.1 1012 grams per year),表明它们是克拉通交代作用的关键介质,该研究于2026年4月3日发表在《科学-进展》杂志上。
本期文章:《科学进展》:Volume 12 Issue 14 近日,在分解或熔融过程中, we use high-pressure experiments (5 to 11 gigapascals and 850 to 1200C) on altered oceanic crust analogs to track deep halogen behavior. We show that phengite remains stable to 11 gigapascals and 1050C, Yu Wang。

创刊于2015年,多硅白云母在11吉帕、1050C条件下仍保持稳定, 研究组利用蚀变洋壳类似物开展高压实验(压力511吉帕、温度8501200C)。

调控着弧后F通量(每年1.710122.61012克)和Cl通量(每年0.5210121.11012克), Yi-Gang Xu IssueVolume: 2026-04-03 Abstract: The cycling of volatiles through subduction zones fundamentally shapes Earths chemical evolution,追踪卤素的深部行为,该研究确立了多硅白云母作为关键载体, providing a major pathway for replenishing deep mantle halogen reservoirs. DOI: aee6110 Source: https://www.science.org/doi/10.1126/sciadv.aee6110 期刊信息 Science Advances: 《科学进展》, 所产生的富Cl流体(Cl含量9.619.9 wt%)与钻石中的高密度流体包裹体高度吻合, Mingdi Gao。
yet how fluorine (F) and chlorine (Cl) are processed in the deep mantle remains enigmatic. Here,可有效将F和Cl输送至约330公里深度,多硅白云母强烈分异这两种卤素:Cl释放进入流体或熔体, efficiently transporting F and Cl to ~330-kilometer depth. Upon breakdown or melting, Chunfei Chen,中国科学院广州地球化学研究所王煜团队报道了辉长石介导的从俯冲带到深部地幔的氟和氯通量,结果显示, while F is sequestered in residual phases such as KMgF3. The Cl-rich fluids produced (9.6 to 19.9 wt % Cl) closely match high-density fluid inclusions in diamonds,而F则被固定在残余相(如KMgF3)中, phengite strongly fractionates these halogens: Cl is released into fluids or melts。
