9505843这个项目将测试一种新的低温退磁技术,用于从加拿大格伦维尔省的岩石中分离磁铁矿中的单磁化和多磁化行为。然后将分离出的磁化强度与标准退磁实验中分离出的磁化强度进行比较,并通过与从相同岩石中获得的长石的40Ar/39Ar光谱进行比较来确定年代。这项研究的结果将对所有的古地磁实验具有重要意义。它们还将有助于完善北美板块的前寒武纪极地漂移路径,这显著提高了对晚前寒武纪板块构造的理解。
英文摘要
9505843 Kodama This project will test a new low -temperature demagnetization technique for isolating single domain magnetization from multi-domain-like behavior in magnetite from rocks of the Grenville province in Canada. The isolated magnetizations will then be compared to those isolated from a standard demagnetization experiment, and will be dated by comparison with 40Ar/39Ar spectra from feldspar gains from the same rocks. The results of this study will be significant for all paleomagnetic experiments. They will also help refine the Precambrian polar wander path for the North American plate, which significantly improve understanding of late Precambrian plate tectonics.
