中文摘要
威尔逊9314142这个项目将改进新生代古地磁石灰刻度,以最大限度地减少噪音,并消除由当前接受的方案产生的板对速率变化中的虚假同步。这将通过以下方式实现:(I)使用速率更快的板对,允许更精确的年龄估计,对于有独立证据表明没有速率变化的时间间隔;(2)将通过计算旋转角度而不是平均距离来消除噪声;(3)将根据多个板对来确定年龄。其结果将是一个改进的时间尺度,它将被广泛应用于大陆和海洋的地质研究。
英文摘要
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.
