一个由伊斯坦布尔理工大学主导的国际研究团队,在伊朗西北部识别并命名了一个此前未被认识的古大陆岩浆弧系统,将其称为“阿塞拜疆大陆岩浆弧” 1。该火山系统形成于晚白垩世时期,具体时间为距今约1.01亿至0.97亿年前 1。这一地质遗迹的发现揭示了古特提斯洋消失过程中的关键演化历史 1。
研究团队综合运用锆石U-Pb测年法、Hf同位素分析以及全岩地球化学等多种技术手段,完成了对该岩浆弧的鉴定与特征描述 1。此次研究得到了包括中国科学院青藏高原研究所、新疆生态与地理研究所以及苏黎世联邦理工学院在内的多个机构合作支持 1。相关研究成果已正式发表于《Geoscience Frontiers》期刊,通讯作者为Ali Mohammadi博士 1。
An international research team led by Istanbul Technical University has identified a previously unrecognized ancient continental magmatic arc in northwestern Iran, naming it the Azerbaijan Continental Magmatic Arc 1. The discovery reveals key geological history regarding the disappearance of the Paleo-Tethys Ocean and was announced on October 28, 2026 1.
The volcanic system formed approximately 101 to 97 million years ago during the Late Cretaceous period 1. Researchers employed zircon U-Pb dating, Hf isotope analysis, and whole-rock geochemistry to characterize the formation 1. Dr. Ali Mohammadi served as the corresponding author for the study, which involved collaborators from the Institute of Tibetan Plateau Research and the Xinjiang Institute of Ecology and Geography under the Chinese Academy of Sciences, as well as ETH Zurich 1. The findings were published in the journal Geoscience Frontiers with DOI 10.1016/j.gsf.2025.102205 1.
