Finite Rotations of the Cocos-Nazca Pacific Plate Circuit

科科斯、纳斯卡和太平洋板块之间的相对运动将在一项运动学研究中确定，该研究扩展了最近关于有限旋转置信区间的工作，以包括描述三板块电路有限旋转所需的六个参数的置信区间。确定的扩散速率（带有强烈的误差条）应该比现有的磁反转时间尺度年轻端校准提供改进。

The relative motion between the Cocos, Nazca and Pacific plates will be determined in a kinematic study that extends recent work on the confidence intervals of finite rotations to encompass confidence intervals on the six parameters necessary to describe finite rotations of a three-plate circuit. The determined spreading rates (with vigorous error bars) should offer an improvement over existing calibrations of the young end of the magnetic reversal time scale.
