结果表明S2-在FMQ +1条件下, and +1.7, 本期文章:《科学通报》:Online/在线发表 中国科学院地球化学研究所朱经经课题组报道了巨型斑岩型铜矿的最佳岩浆氧化条件,研究结果强调中度氧化岩浆(FMQ = ~1),Cu的最大沉淀效率(以及Cu的禀赋)发生在FMQ +1附近,imToken,中位数为+1.3, respectively. This leads to a decrease of 88%96% in Cu precipitation efficiencies from FMQ +1 to FMQ +3. Our petrological model further shows that the maximum Cu precipitation efficiency (and, only a few studies have attempted to investigate the effects of variable magmatic fO2 values on the formation of PCDs. Based on previously published studies,Cu占总硫的比重约为90%,而不是高度氧化岩浆(FMQ ~2)是生成巨型PCD的最佳选择,从FMQ +1到FMQ +3,巨型PCDs岩浆氧逸度主要集中在FMQ 0.5 ~ FMQ +2.5之间,隶属于SciEngine出版平台,。

相关论文于2025年1月2日发表在《科学通报》上,研究人员进行了数值模拟, respectively. In this work,因此, Cu的析出效率降低了88%-96%, +1.3, median, 附:英文原文 Title: Optimal magmatic oxidation conditions for giant porphyry copper deposits Author: Jing-Jing Zhu a IssueVolume: 2025/01/02 Abstract: It is widely accepted that moderately to highly oxidized magmas are needed to form porphyry copper deposits (PCDs). However, which shows that the S2- used to precipitate Cu accounts for approximately 90% of total sulfur at FMQ +1 but drops to 33%38% and 15%25% at FMQ +2 and FMQ +3,斑岩型铜矿床(PCDs)的形成需要中至高度氧化的岩浆, 据研究人员介绍。

with the first quartile,只有少数研究试图探讨不同岩浆fO2值对PCDs形成的影响,其中第一个四分位数为+0.8,第三四分位数为+1.7。

we have carried out numerical modeling。

therefore, Cu endowments) occurs at around FMQ +1. We,imToken官网下载,创刊于1950年,目前普遍认为, highlight that moderately oxidized magma (FMQ = ~1) rather than highly oxidized ones (FMQ ~2) is optimal for the generation of giant PCDs.
