Abstract

The fracture array in the Lewisian basement of NW Scotland is dominated by 2 orthogonal sets. Parallel to and perhaps in part reactivating these fractures are 2 sets of faults, each with apparent normal offset. The NE-trending faults are longer and regionally more significant. The NW-trending faults commonly terminate against NE-trending faults and divide the hanging wall rocks of NE-trending faults into independent blocks. The dominance of NE-trending faults, and the kinematics of fault movements suggest that movement on the faults accommodated NW-SE extension. -from Authors
