Tauxe 9526533 The PI's propose to continue their investigations into the origin of magnetite and magnetic remanence in submarine basaltic glass and to acquire paleointensity data for a globally distributed database throughout the Cenozoic. They will carry out rock magnetic studies and laboratory synthesis of basaltic glasses in order to further understanding of the origin of the magnetite that carries the magnetic remanence in submarine basaltic glass. This research has far-reaching consequences for understanding the nature of the earth's core and generation of the geodynamo, and for reconstructing earth's geomagnetic field history.

托克斯9526533 PI建议继续调查海底玄武岩玻璃中磁铁矿和剩磁的起源，并为整个新生代的全球分布数据库获取古强度数据。 他们将进行岩石磁性研究和玄武岩玻璃的实验室合成，以进一步了解海底玄武岩玻璃中携带剩磁的磁铁矿的起源。 这一研究对于理解地核的性质和地球发电机的产生，以及重建地球地磁场的历史具有深远的影响。
