Plio-Pleistocene Forearc Deformation at a Ridge-Trench- Trench Triple Junction: A Geologic Study of Emerged Coral Reefs and Marine Sedimentary Rocks, New Georgia Island Group

存在许多与山脊-海沟-海沟三重结有关的新构造模型，然而，这些模型很难检验，部分原因是缺乏合适的现代实例。该项目的重点将是与所罗门群岛一个活跃的扩张海脊俯冲有关的差异隆起，那里的海脊轴线与海沟倾斜。晚更新世珊瑚礁的隆起和变形将提供关键的年龄信息和相对于海平面数据的海拔，这是重建海脊俯冲附近的隆升历史所需的。预计结果将提供可应用于暴露较少和较古老的脊-脊-海沟系统的隆起模式和速率。

A number of models exist for the neotectonics involved with a ridge-trench-trench triple junction, however, these are difficult to test, partly due to a scarcity of suitable modern examples. This project will focus on differential uplift associated with the subduction of an active spreading ridge in the Solomon Islands where the ridge axis is oblique to the trench. Uplifted and deformed Late Pleistocene coral reefs will provide critical age information and elevation relative to sea level data required to reconstruct the uplift history in the vicinity of the ridge subduction. Results are expected to provide patterns and rates of uplift that can be applied to less well-exposed and more ancient examples of ridge-ridge-trench systems.
