Recalibration of the Cenozoic Polarity Time Scale

威尔逊9314142 本项目将改进新生代古地磁石灰标尺，以尽量减少噪音，并消除目前公认的方案所产生的板对速率变化中的虚假同步性。 这将通过以下方式实现：（I）使用具有更快速率的板对，允许更精确的年龄估计，对于具有独立证据表明没有发生速率变化的时间间隔;（2）通过计算旋转角度而不是平均距离来消除噪声;（3）将从多个板对确定年龄。 其结果将是一个改进的时间尺度，将广泛用于大陆和海洋地质研究。

Wilson 9314142 This project will refine the Cenozoic paleomagnetic lime scale to minimize noise and remove spurious synchroneities in plate-pair rate changes which are produced by the currently-accepted scheme. This will be accomplished by (I) using plate-pairs with faster rates, permitting more precise age estimates, for time intervals with independent evidence that no rate changes occurred; (2) noise will be removed by calculating rotation angles rather than average distances; (3) ages will be determined from multiple plate pairs. The result will be an improved time scale which will be widely used in geologic studies, both continental and marine.
