Project Overview

Map of the NE Atlantic
Tectonic element map of the NE Atlantic

Recent studies of basin segmentation along the NE Atlantic margins have highlighted the importance of large-scale boundary faults, pre-existing structure, and syn-tectonic volume change (i.e. magmatism), in controlling the geometry and kinematics of rift systems. This project investigates the complex evolution of the inter-rift, or relay, zone where we find evidence for 3-dimensional strains, manifest as multiple sets of ancillary fractures and folds, surrounding the tips of en echelon fractures at cm- to km-scale. Results are used to re-interpret margin-oblique lineaments in the NE Atlantic and inform a new model for rift development and basin segmentation in the region.


Research Aims

  1. Conduct lab-based property analysis of the mechanical and elastic properties of basaltic sequences and investigate the effects of a varying mechanical stratigraphy on crack initiation and fault propagation.
  2. Investigate the 3D propagation and segmentation of normal faults and extension fractures from the scale of individual fractures (cm) to the rift-fault (km) scale in an incipient rift system (the Koa'e fault system, Hawaii) and an evolved rift system (the Krafla fissure swarm, Iceland).
  3. Up-scale observations of segmented normal faults and extension fractures to a basin scale by comparing fault datasets from the Faroe Islands and E Greenland and identify how the geometry of initial rift segments effects the development and distribution of ancillary faults and thus, the segmentation of basins along the NE Atlantic margins.
