The record sections have been reduced to a velocity of 8 km s−1 with observed (coloured lines) and predicted (thin red line) intra-crustal refractions (P1, P2), possible Moho reflections (PmP) and possible mantle refractions (Pn). Thickness of coloured line is proportional to travel time error, based on source-recording station offset. Ray coverage plot showing paths for the selected picked arrivals. Inverted triangle = station location. Blue arrows show the surface with abrupt velocity contrast, interpreted as top of the ophiolite. Grey lines show layers used during modelling of observed traveltimes. a Station S-19 on Transect D4 (Fig. 1). b Station S-15 on Transect D1 (Fig. 1). The uninterpreted record sections are shown in Supplementary Fig. 3.
