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分段规模的结构几何，以此作为更好地了解类似过程的一种手段，这些过程可能在其他高岩浆预算扩散系统中很重要。激发这个项目的特殊特征被称为挠曲带，本质上是在冰岛板状熔岩流地层中形成的非常大规模的褶皱，在这种褶皱中，熔岩流向内向宽阔的岩浆中心倾斜。
