Recalibration of the Cenozoic Polarity Time Scale

该项目将改进新生代古磁石灰标度，以最大限度地减少噪声，并消除目前接受的方案产生的板对速率变化的虚假同步性。这将通过(I)使用速度更快的板对来实现，允许更精确的年龄估计，对于没有发生速率变化的独立证据的时间间隔；(2)通过计算旋转角度而不是平均距离来去除噪声；(3)年龄将由多个板对确定。结果将是一个改进的时间尺度，它将广泛用于大陆和海洋的地质研究。

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.
