Location of magnetic and seismic profiles in the research areas. Maps: Generic Mapping Tools36. (a) Overview map showing the location of the research areas in this conjugate margin study. The red and purple boxes indicate the locations of newly-gathered magnetic and seismic data. Black lines mark the locations of newly-acquired seismic refraction data. (b) Location of deep seismic line 20170300. Black circles show the positions of the seismic stations on the seafloor and onshore Sri Lanka. White lines show the locations of newly acquired magnetic profiles. (c) Locations of the deep seismic profiles in the Enderby Basin and Princess Elizabeth Trough. Black circles represent the locations of OBS and OBH stations. ODP drill sites are marked in orange. Helicopter borne magnetic data (blue and red) were acquired in corridors centred on and parallel to the deep seismic lines. For clarity, they are shown here shifted eastwards.
