Abstract

A sequence stratigraphic study of the Pliocene age sedimentary rocks was conducted in the central part of Taranaki basin, which is located offshore in the western coast of Taranaki Penisula, New Zealand. The study area is approximately 217.4.km2 consisting of an anticline cut by some faults in the southeastern part of the study area. The purpose of this study was to identify the seismic facies and to determine the seismic sequence stratigraphic boundaries of the Pliocene deposits. Ten seismic sections and three wells were used in this study where many seismic facies were detected such as parallel, sub-parallel, continuous, sub-continuous, wavy, free reflection, chaotic, high amplitude-high frequency and high amplitude-low frequency. Based on reflection terminations and seismic facies two sequence boundaries with their chronostratigraphic units were determined. Sequence boundary 1 (SB1) separates Giant Foresets Formation upper and Giant Foresets Formation middle formations. While sequence boundary 2 separates Giant middle and Giant lower formations. Synthetic seismogram was developed from density and sonic logs and was correlated with the seismic section for locating the sequence boundaries. SB2 is characterized by erosional truncation as shown by the presence of toplaps and downlaps reflection terminations in the central part of the seismic section. A low-amplitude high-frequency reflection was observed above sequence boundary SB1 while high amplitude-low frequency reflection was observed below SB2.
