Symposium on "Archean Tectonic Styles: Constraints and Inferences" Concludes Successfully

On May 17–18, 2025, the international symposium "Archean Tectonic Styles: Constraints and Inferences", jointly organized by the Center for Global Tectonics (China University of Geosciences, Wuhan), the University of Science and Technology of China, and the International Lithosphere Program (ILP), was successfully held in Wuhan, China. The event brought together over 150 experts from more than 40 research institutions and universities, including the Chinese Academy of Sciences, Peking University, and Nanjing University. Distinguished attendees included Academicians Yongfei Zheng, Mingguo Zhai, Guochun Zhao, Wenjiao Xiao, and Qiuming Cheng, who engaged in in-depth discussions on the globally frontier topic of Archean tectonic evolution. Professor Lu Wang, as the chief organizer, ensured the smooth execution of 33 oral presentations and 27 poster sessions.

During the opening ceremony, Professor Jianwei Li, President of China University of Geosciences (Wuhan), delivered a speech on behalf of the university. Professor Timothy Kusky spoke on behalf of the Center for Global Tectonics. Academician Mingguo Zhai commemorated the pioneering contributions of the late scholar Professor Brian F. Windley to early Earth tectonic research. Subsequently, nine discipline leaders including Academicians Guochun Zhao and Mingguo Zhai presented keynote reports. The conference content covered:

Tectonic observation and modeling: Scholars reconstructed Hadean-Archean tectonic styles through multidisciplinary approaches such as machine learning, structural geology, petrology, and geochemistry.

Tectonic evolution and metallogenesis: Participants deeply explored tectonic controls on mineral enrichment processes, including chromite deposits in Archean greenstone belts (by Academician Jingsui Yang) and BIF iron ores.

Environmental co-evolution: Academician Yongfei Zheng pointed out that the "dialectical relationship between observation and interpretation" is key to deciphering Archean oxidation. Conference reports also discussed potential impacts of Archean tectonic processes on Earth's heat production, climate and marine environmental evolution, continental exposure, weathering, and life evolution.

Professor Timothy Kusky, Director of the Center for Global Tectonics at China University of Geosciences (Wuhan), stated: "This conference has established an important collaborative framework for decoding Earth's earliest tectonic style codes."

"太古宙构造样式：约束与推断"学术研讨会圆满落幕‌

2025年5月17-18日，由中国地质大学（武汉）全球大地构造中心、中国科学技术大学及国际岩石圈计划（ILP）联合主办的 “太古宙构造样式：约束与推断”学术研讨会 在武汉市成功举办。会议汇聚了来自中国科学院、北京大学、南京大学等40余家科研院所及高校的150余位专家学者参会，包括郑永飞院士、翟明国院士、赵国春院士、肖文交院士、成秋明院士，围绕太古宙构造样式这一国际前沿展开深度交流。王璐教授作为会议主要筹备人，保障了本次会议33场口头报告和和27个展板报告的顺利开展。

开幕式中，中国地质大学（武汉）校长李建威代表学校致辞，Timothy Kusky教授代表全球大地构造中心致辞，翟明国院士缅怀已故学者Brain F. Windley教授对早期地球构造研究的开创性贡献。随后，赵国春院士、翟明国院士等9位学科带头人做主题报告，本次会议内容涵盖：

1.            构造观察与模拟：学者们通过机器学习、构造地质学、岩石学、地球化学等多学科手段，重建冥古宙-太古宙构造样式。

2.            构造演化与成矿作用：针对太古宙绿岩带铬铁矿（杨经绥院士）、BIF铁矿等成矿过程，与会者深入探讨了构造对资源富集的控制机制。

3.            环境协同演化：郑永飞院士指出“观测与解释的辩证关系”是破解太古宙氧化的关键。会议报告同样探讨了太古宙构造过程对地球热量产出、气候与海洋环境演变、大陆出露、风化作用及生命演化的潜在影响。

中国地质大学（武汉）全球大地构造中心主任Timothy Kusky表示："这次会议为破解地球最早期的构造样式密码建立了重要合作框架"。
