    Funding This work was funded through a postgraduate scholarship from the University of Adelaide, Faculty of Engineering Computer and Mathematical Sciences, and also by ASEG Research Foundation Grant no. RF19P01. These funding sources had no involvement in study design; in the collection, analysis and interpretation of data; in the writing of the report; or in the decision to submit the article for publication. Acknowledgements We would like to thank Iain Campbell, formerly Chief Petroleum Geophysicist at the South Australian Department for Energy and Mining for arranging the stitching together of multiple SEGY component files for the Indian 3D seismic reflection survey which was instrumental for interpretation of the Toro Volcanic Complex. We would also like to thank both Simon Lang and particularly Victorien Paumard of the Centre for Energy Geoscience, University of Western Australia, for numerous discussions around the development of the Barrow Delta in the Exmouth Sub-Basin and Exmouth Plateau. We thank Tiago Alves for editorial guidance, and the constructive reviews provided by Victorien Paumard, Natasha Stanton, Gerome Calves, Chris Elders, Kamaldeen Omosanya and one anonymous referee.Peer reviewe

    Contemporary stress orientations in the Faroe-Shetland region

    The Faroe-Shetland Region (FSR) of the NE Atlantic continental margin contains a number of complexly structured Mesozoic-Palaeogene-age rift basins, but in comparison to the contiguous British Isles and North Sea Basin, the state of crustal stress in the FSR is poorly understood. The orientation of maximum horizontal compressional stress (σHmax) across most of NW Europe is ~NW-SE, which is considered to be controlled by forces acting at the plate boundaries. We have determined 16 B-D quality σHmax orientations based on borehole breakouts interpreted in petroleum wells, and define three distinct stress provinces within the FSR. Stress orientations in the NE are ~NW-SE, consistent with the regional pattern of stresses in NW Europe and local neotectonic structural trends. However, contemporary stress orientations in the central and SW of the FSR exhibit short-wavelength (distances <10-50 km) variation, with NE-SW, N-S and E-W orientations that are parallel or sub-parallel to underlying structural trends. This variation is interpreted in terms of stress deflections towards weak faults that downthrow the Mesozoic-Cenozoic sedimentary successions against basement highs. These local-scale sources are superposed on a background ~WNW-ESE σHmax orientation that is controlled by both plate boundary forces and regional-scale sources of stresses
