“…Palaeogeographic mapping is based on revised structural and stratigraphic frameworks for the CNWS (Abbott et al, 2019;Orlov et al this volume). Constraints for palaeogeographic mapping are limited over most of the study area, so a gross depositional facies (GDF) approach was adopted based on extrapolation of well lithology data, seismic facies, and information from analogous intervals in adjacent basins.…”
