Abstract/Summary

This report describes a project to evaluate, in the area southeast of the Faroes, the structural element map of the Faroe-Shetland Basin (FSB) produced during Phase 2 of the consortium (Quinn et al., 2014) in the light of new interpretations of reprocessed seismic data and taking into consideration the potential field anomalies in the area. Interpretations were made along five reprocessed seismic lines across the area, which placed the base basalt reflector considerably deeper than has been done previously. Identification of reflectors beneath base basalt is very patchy, with little evidence of basement highs. Within the basalts, identification of different volcanic facies was made. Potential field models were constructed along each of the five profiles, and illustrate that the anomalies in the area can be accounted for by geometry and property variations within the lava succession, although these are not always supported by seismic evidence. Taken together, the seismic and potential field interpretations do not strongly support the existence of previously mapped basement highs under the lavas, and suggest that some revision of the structural elements map is necessary in the area southeast of the Faroes.
