This project will investigate segment-scale structural geometries developed in Iceland as a means to better understand analogous processes that may be important in other high-magma budget spreading systems. The particular features that inspire this project are referred to as flexure zones and are essentially very large-scale folds developed in the sheet-like lava flow stratigraphy of Iceland in which lava flows dip inwards toward broadly coeveal magmatic centers.

该项目将研究冰岛开发的段尺度结构几何形状，以更好地理解在其他高岩浆预算扩张系统中可能很重要的类似过程。 激发该项目的特殊特征被称为挠曲区，基本上是冰岛片状熔岩流地层中发育的非常大规模的褶皱，其中熔岩流向内倾斜，流向广泛的岩浆中心。
