Structure and seismic stratigraphy of the western Challenger Plateau

Abstract: Surveys conducted by the New Zealand Department of Scientific and Industrial Research in 1987 and1989 provided a high-quality data set which, when incorporated with older data, permits a detailed analysis of sedimentation, volcanism, and geologic evolution of the region. AbstractThe Challenger Basin is a newly discovered sedimentary basin beneath the western margin of the Challenger Plateau. Seismic and gravity data near the site of two Deep Sea Drilling Project holes (DSDP 284 and 593) show more than 2 km of … Show more

“…Long offset seismic refraction surveys record a depth to the mantle of c. 15 km under the New Caledonia Basin, 20 km under the Lord Howe Rise and Norfolk Ridge (Shor et al 1971), and c. 25 km beneath the Northland peninsula (Stern et al 1987). Marine gravity studies reveal similar crustal thicknesses under the other major ridges and reduced thicknesses of 15-20 km under the basins (Uruski & Wood 1991;Wood 1991;Zhu & Symonds 1994). Evidence for Cretaceous ductile defonnation due to northeast extension is found in core complexes in the western and northern South Island dated as 114 ± 18 Ma and 109.6 ± 1.7 Ma (Tulloch & Kimbrough 1989;Muiret al 1994).…”

“…The structure of the Challenger Plateau and Lord Howe Rise is relatively simple, with rift zones along the Tasman and New Caledonia Basin margins (Jongsma & Mutter 1978;Wood 1991). The central part of the plateaus is characterised by shallow basement and volcanic features (Willcox et al 1980;Wood 1991Wood , 1993.…”

“…These rocks were deposited in extensional basins or half grabens and are widespread throughout the New Zealand crustal block from Northland to the Great South Basin and western Southland (Field & Browne 1989;Wood et al 1989;Uruski & Turnbull 1991;Wood 1991;Bishop 1992). Most occur in offshore regions where only limited core data are available; by necessity, much has to be inferred from their seismic characteristics.…”
