ABR: SeaMARC II Investigation of the Easter Microplate

在此基础上的更新，P.I.将继续分析在复活节微板上的两个Sea.Beam和SeaMarc II测绘项目上收集的数据。DTE的成就包括：建立了构造环境；绘制了围绕该地区的传播海脊和转换断层；扩张速度是迄今研究过的任何海脊系统中最快的；超过一定速度，扩张海脊不被转换的断层分割；微板块起源于约4.5 Ma，至少在过去0.75 Ma作为刚体旋转。这笔最终资金将使PI能够完成在SeaMarc II数据中观察到的构造线条的测绘。

In this Accomplishment.Based renewal, the P.I. will continue the analysis of data collected on two Sea.Beam and SeaMarc II mapping projects on the Easter Microplate. Accomplishments to dte include establishment of the tectonic setting; mapping of propogating ridges and transform faults that boundt the region; spreading rates are the fastest of any ridge system yet studied; beyond a certain rate, spreading ridges are not segmented by transformed faults; the microplate originated about 4.5 Ma and has been rotating as a rigid body for at least the last 0.75 Ma. This final funding will allow the PI to complete mapping of the structural lineaments observed in the SeaMarc II data.
