“…We agree with Waterhouse (1989), Milne & Quick (1999), Strong et al (1999), and Cook (1999) that the volcaniclastic strata in the bottom of awhitu-1 and Waka Nui-1 correlate with Murihiku Terrane (Ballance & Campbell 1993;edbrooke 2001,2005Campbell et al 2003).…”

“…The Permian-Cretaceous Murihiku Terrane is New Zealand's most fossiliferous, least metamorphosed, and least deformed tectonostratigraphic terrane (Ballance & Campbell 1993;Isaac et al 1994;Campbell et al 2003). It lies withm the Eastern Province (i.e., east of the Median Batholith), between the Permian Dun Mountain Ophiolite Belt and the Permian Brook Street arc terrane.…”

“…It represents a long-lived basin that was receiving detritus possibly from the nearby Carboniferous-Cretaceous Median Batholith arc, but which escaped Jurassic-Cretaceous penetrative deformation andmetamorphism that affected both the Median Batholith to the west and Otago Schist to the east. In terms of internal stratigraphy, the Murihiku Terrane comprises the Permian to Late Jurassic Murihiku Supergroup and the Late Jurassic to Early Cretaceous Waipa Supergroup, both of which are divided into a number of groups and formations (Campbell et al 2003).…”

Core and cuttings of sandstone and mudstone from Waka Nui-1, an offshore oil exploration well west of Northland, and from Awhitu-1, a water bore in western Auckland, add to the growing number of samples retrieved from otherwise inaccessible basement of the Zealandia continent. On the basis of pollen and spores, the sedim entary rocks at the bottom of Waka Nui-1 are dated as Early-Middle Jurassic, and rocks from Awhitu-1 are Late Jurassic. On the basis of age, sandstone petrology, and geographic position, a correlation of rocks in both wells with Murihiku Terrane is probable. In New Zealand, Jurassic sedimentary rocks have usually been interpreted in a tectonostratigraphic terrane context. An alternative way to look at the New Zealand Late Jurassic to Early Cretaceous sedimentary rocks is as potentially interconnected forearc, intra-arc, back-arc, and intracontinental basins that evolved adjacent to an active margin.

“…The Murihiku Supergroup was initially defined by Campbell & Coombs (1966), and has been recently amended by Campbell et al (2003) to include Late Permian carbonate sequences in the Kuriwao Group in eastern Southland (Campbell et al 2001). The Murihiku Supergroup (or terrane) in the western North Island comprises five groups of rocks and ranges in age from Late Triassic (Oretian Stage) to at least (Campbell et al 2001).…”

The Murihiku Terrane in the North Island was a forearc basin adjacent to a volcanic arc along the eastern margin of Gondwana during the Mesozoic. The rocks that infill the basin are mainly volcaniclastic sandstones and mudstones, often turbiditic, with sparse shellbeds, rhyolitic tuffs, carbonaceous sandstones, plant beds, concretionary horizons, and rare thick granitoid-rich conglomerates. Petrographic studies of the rock fragments in the sandstones show that andesites are the dominant lithic type, but there is a wide range of other lithologies, including dacites, rhyolites, ignimbrites, granitoids, quartzofeldspathic mica schists, rare amphibolites, and reworked mudstones and sandstones. The sandstones are texturally and mineralogically immature and suggest deposition relatively close to a source of high relief, undergoing physical rather than chemical weathering in cool-to cold-temperate conditions. Geochemical analyses of 67 whole-rock volcaniclastic sandstones and siltstones indicate that they were derived from an active and dissected volcanic arc in a convergent margin setting built upon relatively thin continental crust. Modal petrographic data and whole-rock geochemistry both confirm that there were systematic variations with time in the composition of clastic material being supplied to the basin. From the Late Triassic to Middle Jurassic, there was a decrease in silicic volcanic material, plutonics, and metamorphics, and an increase in the supply of andesitic detritus. This was followed in the Late Jurassic by a broader range of volcanic detritus, varying from basaltic andesite to rhyolite, which may have been caused by progressive extension of the volcanic arc and thinning of the crust, a precursor to the breakup of Gondwana in the Early-Middle Cretaceous. Comparison with the Southland segment of the Murihiku Terrane in the South Island suggests that there were significant along-arc source variations, with relatively less silicic but greater andesitic and continental crust contributions in the North Island than in Southland. This may be analogous to the modern Taupo-Kermadec arc where there is a south-north along-arc transition from a continental to an oceanic arc.
