| The newly mapped Kapiti-Manawatu Fault System (KMFS) in southern North Island, New Zealand, accommodated similar to 3.5 km of basement throw over the last 3 Myr. Along-strike throw profiles are generated using seven stratigraphic markers, interpreted from seismic reflection profiles acquired < 3 km apart. The profiles are symmetrical about their point of maximum displacement, and cumulative profiles suggest that the reverse fault system behaves coherently. The KMFS originates from the reactivation of extensional structures, with fault lengths remaining constant over time. Contractional deformation started at circa 1750 +/- 400 ka. Maximum dip-slip rates along individual faults are 1.77 +/- 0.53 and 0.74 +/- 0.22 mm yr(-1) for the 0 - 120 and 120 - 1350... |
