U.S.-France Cooperative Research: Geodynamics and Eustasy atan Active Plate Boundary in the Pacific Atolls

这个为期两年的奖项支持迈阿密大学的Donald F. McNeill和巴黎大学（南）的Djafar Aissaoui在海洋地质学方面的美法合作研究。他们研究的目的是校准和细化与活跃的俯冲板块边界相关的地球动力学事件的时间。研究人员将把碳酸盐磁地层学应用于南太平洋忠诚群岛的一个隆起的环礁。麦克尼尔博士为这次合作带来了岩石磁学和浅水碳酸盐岩磁地层测年方面的经验。他建造了一个用于数据分析的超导磁学实验室。Aissaoui博士对环礁的地质和地层学的知识补充了这一点。碳酸盐磁地层学是一种新的技术，用于确定活动板块边界的运动速度和提取过去海平面事件的数据。本研究结果将确定其在活动板块边界研究的可行性，并可能导致其在地球动力学和板块构造研究中的广泛应用。

This two-year award supports U.S.-France cooperative research in marine geology between Donald F. McNeill of the University of Miami and Djafar Aissaoui of the University of Paris (South). The objective of their research is to calibrate and refine the timing of geodynamic events associated with an active, subducting plate boundary. The investigators will apply carbonate magnetostratigraphy to an uplifted atoll in the Loyalty Islands of the South Pacific. Dr. McNeill brings to this collaboration experience in rock magnetics and magnetostratigraphic dating of shallow-water carbonates. He has constructed a superconducting magnetics laboratory for data analysis. This is complemented by Dr. Aissaoui's knowledge about the Atoll's geology and stratigraphy. Carbonate magnetostratigraphy is a novel technique for timing and determining rates of motion at active plate boundaries and for extracting data on past sea level events. Results from this research will determine its feasibility for studies at active plate boundaries and could lead to its widespread use for research in geodynamics and plate tectonics.
