EAR PF: Geomagnetic paleointensity from time-equivalent high and low latitude magmatic events in the late Mesoproterozoic

尼古拉斯·L·斯旺森-海塞尔博士获得了明尼苏达大学的EAR博士后奖学金，以开展一项研究和教育计划。他将研究大约1.1年的同时代火成岩。它们被放置在不同的纬度，记录了当时地球磁场的特征。调查的重点将是开发北美中大陆裂谷(来自明尼苏达州北部和安大略省)和乌姆孔多大火成岩省(来自南非和博茨瓦纳)的熔岩和侵入体的古地磁强度记录。这些古强度数据将被用来评估偶极磁场的强度是否可预测地依赖于纬度，并检查磁场强度如何随时间变化。因此，可以准确地重建大陆过去的位置和地核的演化。Nicholas Swanson-Hysell博士将为主办机构和Carleton学院的课程开发课程活动。这些练习将在复杂性和深度方面进行，在某些情况下，学生将进入实地收集样本，然后在实验室进行分析。本科生还将参与该项目本身的研究，并将在该项目的两个野外赛季期间陪同Swanson-Hysell博士进入实地。作为这项研究的结果公布的所有数据将被贡献给MAGIC数据库，并向科学界提供。

Dr. Nicholas L. Swanson-Hysell has been granted an EAR Postdoctoral Fellowship to carry out a research and education plan at the University of Minnesota. He will examine contemporaneous igneous rocks about 1.1. billion years old that were emplaced at different latitudes, recording the characteristics of the Earth's magnetic field at the time. The investigation will focus on developing magnetic paleointensity records from lavas and intrusions of the North American mid-continent rift (from Northern Minnesota and Ontario) and the Umkondo large igneous province (from South Africa and Botswana). These paleointensity data will be used to evaluate whether the strength of a dipolar magnetic field is predictably dependent on latitude and to examine how the strength of the magnetic field changed through time. Thus, accurate reconstructions of the position of the continents in the past and the evolution of the Earth's core can be made. Dr. Nicholas Swanson-Hysell will develop curricular activities for courses both at the host institution and Carleton College. These exercises will range in complexity and depth and will, in some cases, have students go into the field to collect samples that they then analyzed in the laboratory. Undergraduate students will also be involved in research for the project itself and will accompany Dr. Swanson-Hysell into the field during the project's two field seasons. All data published as a result of this study will be contributed to the MagIC database and made available to the scientific community.
