RUI: Detailed Paleomagnetic Study of the Matuyama- Brunhes Reversal from Lavas on Tahiti, French Polynesia

霍夫曼9418862现在围绕地磁反转研究的激烈争论--关于古地磁场在极性转换期间是否有地理上的偏见--激发了整个SEDI社区的极大兴趣。 令人兴奋的部分原因是，这些古地磁记录可能能够提供有关长期核幔相互作用和地球发电机状态的直接信息。 工作计划是在塔希提岛上尽可能多地寻找熔岩序列，记录Matuyama-Brunhes反转期间的现场行为。 所有R-N过渡带将进行放射性年龄测定。 将对所有确认的M/B序列进行详细采样，然后编制综合记录。 ****

Hoffman 9418862 The lively controversy now encircling geomagnetic reversal studies--as to whether the paleomagnetic field is geographically biased during polarity transitions--has stimulated considerable interest throughout the SEDI community. The excitement in part comes from the possibility that these paleomagnetic records may be capable of providing direct information about long-term core-mantle interactions and the state of the geodynamo. The work plan is to search out as many sequences of lava as may be accessible on Tahiti that record field behavior during the Matuyama-Brunhes reversal. All R-N transition zones will be subjected to radiometric age determination. A detailed sampling of all confirmed M/B sequences will be conducted, followed by the development of a composite record. ****
