Seismic Studies in the Region of Northern Skye and the Little Minch

Smythe, David Kenneth (1987) Seismic Studies in the Region of Northern Skye and the Little Minch. PhD thesis, University of Glasgow.

Abstract

The northern Skye-Little Minch region is one of the most accessible regions on the continental shelf where the relationship between intra-continental extensional basins and passive margin formation might be investigated. Can the structure and infill of the presumed sedimentary basin here tell us something about the age of the nearby oceanic Rockall Trough? A variety of geophysical tools are used to evaluate the structure and infill of the basin. Multichannel seismic reflection at six sites in northern Skye, and marine sonobuoy refraction lines in the Little Minch (both using dynamite sources) are supplemented by new and existing shallow seismic profiling (sparker) data. Gravity modelling elucidates the 3-dimensional structure. The offshore geological map of the Little Minch is compiled from possibly the most comprehensive coverage of high resolution profiles of any area on the NW European shelf. The basin is bounded on the NW by the Minch Fault, which is shown to be the reactivated Outer Isles Thrust, and which now dips ESE or SE at about 20
