各位老师、同学：
应邱华宁研究员的邀请，中国科学院“国际人才计划”2016“国际杰出学者”BradS.Singer教授将于本月15-18日到我所学术访问与交流，并举行系列讲座，欢迎大家积极参加。
报告一：7月16日（星期六）上午10:00，地点：综合楼702会议室
报告题目：The multi-collector revolution in 40Ar/39Ar dating: implications for time scale calibration
报告二：7月16日（星期六）下午15:30，地点：图书情报楼64座会议室
报告题目：The large, restless, rhyolitic magma system at Laguna del Maule, southern Andes: Its dynamics and hazards
Brad S. Singer教授是美国威斯康星大学Ar-Ar实验室主任，主要研究方向为高精度Ar-Ar年代学及其应用，是国际地质年代学组织Earthtime的组织者之一，在提高定年精度和标定国际地质年表方面做出了重要贡献。
Professor Singer’s research efforts are focused on the origin and evolution of arc magma, the timingand longevity of geomagnetic polarity reversals recorded by lava flows, and Quaternary paleoclimate in the southern hemisphere. Current projects involve geologic mapping and sample collection in the field, geochemical and isotopic characterization of volcanic rocks and their phenocrysts, paleomagnetic analysis, and dating using 40Ar/39Ar or cosmogenic surface exposure methods. Technological advances now poise the 40Ar/39Ar dating method to revolutionize the timescale for Pleistocene and even Holocene volcanism.
