Abstract: The structure and stratigraphy of the southern area of the offshore Taranaki Basin has been interpreted using seismic reflection data, modelled and depth converted as part of the 4D Taranaki Project. This report provides an overview of the procedures applied and the interpretation and modelling results. Fifteen seismic horizons and over 200 faults have been identified and interpreted to reflect the tectonostratigraphic evolution of the southern Taranaki Basin. Horizons bound regionally extensive, essentially time-equivalent stratigraphic intervals. This report describes the seismic reflection character of these horizons and their associated depositional units. The seismic horizons and faults have been modelled in time, to produce a series of time structure maps and isochron (time thickness) maps. In order to depth convert the modelled faults and horizons a velocity model was constructed that describes regional velocity trends throughout the study area. A series of depth structure and isopach (thickness)maps have been produced. The isochron maps are appended to this report and digital time and depth products, PDF map sheets and the velocity model are additionally available. (auth)
