Figure F18. The Expedition 317 drilling transect across the shelf and upper slope of the Canterbury Basin permits correlation of lithology to seismic sequence boundaries. Lithologic contacts and their overlying associated facies were documented, and preliminary correlations were made to the predicted depths of sequence boundaries. At Sites U1352 and U1354, at which recovery was high, there is good correlation between the sedimentary and seismic records, particularly above seismic sequence boundary U10. The figure illustrates the depths of lithologic contacts at each site (e.g., inner shelf, IS-E1 [99 m]). Seismic sequence boundaries U19–U5 are shown schematically, intersecting each site at their predicted depths. Future shore-based studies will expand on these initial results. Black lines = seismic sequence boundaries, red lines = lithologic boundaries. MP = Marshall Paraconformity.
