应生物地质与环境地质国家重点实验室、陆内火山与地震教育部重点实验室、地球物理与信息技术学院姚硕教授邀请,法国巴黎地球物理研究所Mark Wieczorek教授将来我校做学术报告。


题目:An overview of lunar magnetism: from rocks, to impacts, to dynamos

时间:2024年05月28日下午15:00-17:00

地点:地大国际会议中心第7会议室


报告人简介: Wieczorek教授现就职于法国巴黎地球物理研究所(IPGP),为法国科学院任命的科研所长(director of research (CNRS)at IPGP),是行星和空间科学方向负责人,曾任JGR-planets主编(editor-in-chief)。主要研究方向为类地行星和月球的重力场、磁场、内部结构和地质演化过程。担任多个著名探测任务的CoI,包括月球GRAIL, SMART-1, Chandrayann-1,火星Insight,水星Bepicolombo等。


报告摘要:The Moon was once though to be a cold undifferentiated body that never could have been capable of generating an internal Earth-like magnetic field. It thus came as a surprise to find that many of the lunar rocks collected during the Apollo missions were magnetized, and that orbital magnetic field data showed portions of the crust to be associated with strong magnetic anomalies. The evidence that the Moon had a long lived magnetic field generated by a core dynamo will be summarized in this talk, and the various models that have been proposed to power the dynamo will described. The strongest magnetic anomalies appear to be correlate with the large impact basins on the Moon, and it will be argued that the materials responsible for these anomalies are derived from remnants of the iron-rich projectiles that formed these basins.
