Reversal Records from Leg 1 - Investigation of Records and Use of Be to Test Global Intensity Fluctuations

9316921富勒国际公司将测量和分析不同岩心的天然剩磁参数，这些岩心携带着ODP145段的反转记录，这些记录显示了马图亚山-布鲁内斯过渡期间磁强度记录的波动。这将包括紧接在反转之前和之后的区段，其距离相当于数千年。将进行岩石磁性测量，如磁滞回线、低温反转测量、IRM采集和居里温度测定，以确定实际矿物和表征剩磁。这些测量将得到X射线衍射和对逆转带内不同深度的物质的微观研究的补充。PI还将开发一个模型来模拟过渡虚拟地磁极的首选纵向带，该模型最初将采取核心表面磁通束的几何模拟的形式。****

9316921 Fuller The PI will carry out measurements and analysis of natural remanence magnetism parameters for the sections of the various cores carrying the reversal records from ODP Leg 145, which demonstrate fluctuations in the magnetic intensity record within the Matuyama-Brunhes transition. This will include the sections immediately prior to and following the reversal for distances corresponding to several thousand years. Rock magnetic measurements such as hysteresis loops, low temperature inversions measurements, IRM acquisition, and Curie temperature determinations will be performed in order to determine the actual minerals and characterize the magnetic remanence. These measurements will be supplemented by x-ray diffraction and microscopic studies of the material at various depths within the reversal zone. The PI will also develop a model to simulate the preferred longitudinal bands for the transitional virtual geomagnetic poles that will initially take the form of a geometric simulation of flux bundles on the core surface. ****
