“…Considering the Tertiary age of development of the plate boundary through New Zealand (Sporli 1980;Stock & Molnar 1982;Ballance 1988;Sutherland 1995), the Owahanga River region appears to be in a good position t < record the initiation and development of the deformation ir the coastal ranges. We examine the geometry and kinematic of the bounding faults, identify the lithostratigraphic conten: and internal deformation of the strips, and deduce the timinj of the juxtaposition of tectonic strips within the coaslal ranges.…”

“…1). In eastern North Island, deformation associated with the plate boundary changes from the axial ranges in the west, where active dextral strike-slip is predominant (Kingma 1967;Lensen 1968;Sporli 1980;Cashman et al 1992) to the offshore accretionary Hikurangi prism in the east, characterised by imbricated thrusts (Lewis 1980;Davey et al 1986;Lewis & Pettinga 1993). Between these two domains are, from west to east, a forearc basin, the coastal ranges, and the continental shelf.…”

“…In spite of all these uncertainties, broad correlations have been accepted widely across Cook Strait: a regional extension of basement rocks from Northwest Nelson to the subsurface of the Taranaki Oil Province (the "Foreland" rocks of Sporli, 1980); the Junction Magnetic Anomaly (Hatherton and Sibson, 1970) meeting the Dun Mountain Ophiolite Belt (Coombs et al, 1976); even correlation between specific faults across the Strait (Suggate eta/., 1978: fig. 10.1); and in the east the presence of the Torlesse Supergroup correlating broadly across the Strait, if not in precise age.…”

“…Up to the end of Early Cretaceous Rangitata Orogeny, the history of New Zealand was that of a Pacific margin of Gondwanaland (Spörli, 1980). In the Late Cretaceous, widespread block faulting and graben formation heralded the break-up of this margin (Austin, 1973a, b).…”

Seismic profiles obtained from the eastern side of New Zealand, in transit to and from Site 594, illustrate the evolution of the western end of the Chatham Rise and the southern extremity of the Hikurangi Trough. They show several unconformities and several major changes in tectonic and depositional regime. The unconformities represent major changes in oceanic circulation, possibly triggered by large lowerings of sea level in the late Oligocene and late Miocene. Tectonism is exemplified by a Late Cretaceous phase of block faulting, heralding the rift from Gondwanaland, and by Plio-Pleistocene normal faulting on the northern flank of the rise antithetic to the oblique-collision plate boundary in the southern Hikurangi Trough. This active normal faulting may indicate that the northwestern corner of Chatham Rise continental crust is being dragged down with the subducting slab to the north. The depositional regime has changed from Late Cretaceous infilling of fault-angle depressions, through an early Tertiary transgression and mid-Tertiary carbonate drape, to a late Miocene-Recent sequence recording repeated glacial-interglacial events. This upper stratified unit onlaps a late Miocene erosion/phosphatization unconformity toward the crest of the rise. It is locally truncated by a slope-parallel erosion surface, with downslope buildup, which may indicate either current scour and deposition or mass movement. INTRODUCTION BackgroundIn transit between Cook Strait and Site 594, the Glomar Challenger obtained seismic profiles along approximately 900 km of ship's track. Because they are tied to borehole data and because they cross areas where tracks are sparse, the Glomar Challenger profiles provide a significant increase in our understanding of the stratigraphy of eastern New Zealand and of tectonism in continental crust adjacent to an oblique-collision plate boundary.In this paper we integrate the Glomar Challenger profiles with published syntheses, with seismic data obtained by D.S.I.R. divisions, and with compilations of oil company data on open file at the New Zealand Geological Survey. Oil company data used in this study include profiles collected by Mobil Oil Corporation, Magellan Petroleum (New Zealand) Ltd., Australian Gulf Oil company, and B.P. Shell Todd (Chatham Rise) Ltd. Geomorphological SettingThe Glomar Challenger profiles traverse the Mernoo Saddle, a depression between the continental shelf of eastern New Zealand and the east-west-trending Chatham Rise ( Fig. 1; Fig. 3, later). The saddle's sill depth is over 500 m deep, contrasting with shelf depths to east Kennett, J. P., von der Borch, C. C, et al., Init. Repts. DSDP, 90: Washington (U.S. Govt. Printing Office).
