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

有许多新构造模型涉及脊-沟-沟三联结，然而，这些模型很难检验，部分原因是缺乏合适的现代例子。该项目将重点研究与所罗门群岛活跃伸展脊俯冲相关的差异隆起，该脊轴与海沟斜向。隆起和变形的晚更新世珊瑚礁将为重建洋脊俯冲附近的隆起历史提供关键的年龄信息和相对于海平面的海拔高度数据。结果有望提供隆起的模式和速率，可以应用于较少暴露的和更古老的脊-脊-沟系统的例子。

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.
