Three Dimensional Gravity and Magnetics Studyof the Transiions from Rifting to Seafloor Spreading in the Northern Mariana Arc.

这项研究将对马里亚纳海槽北端附近现有的地球物理数据进行三维重力和磁学解释，该海槽似乎正在积极地经历从裂解地壳到扩张地壳的转变。这项研究将利用测深、重力和磁学来计算标准地球物理参数，并计算出这个弧后盆地的海底磁化解。PI将与P·弗莱尔(夏威夷大学)和日本地质调查局的科学家们提议的和长期的构造和岩石学工作合作。

This study will use a three.dimensional gravity and magnetics interpretation of existing geophysical data near the northern end of the Mariana Trough, which appears to be actively undergoing the transition from rifted to spreading crust. The study will utilize bathymetric, gravity and magnetics to calculate standard geophysical parameters and to claculate a sea floor magnetization solution in this backarc basin. The PI will collaborate with the proposed and ongoiong structural and petrological work of P. Fryer (University of Hawaii) and scientists from the Geological Survey of Japan.
