“…Waioeka petrofacies and their boundaries were confirmed by Leverenz (1999). Kear & Mortimer (2003) On the north and northwestern flanks of the Ruahine and Kaweka Ranges, probable Torlesse Supergroup rocks (Mortimer 1995), similar to those of the Wellington region, are extensive but unfossiliferous. In the Kaimanawa Range ( Fig.…”

“…The fission track ages are consistent with the more precisely determined UPb detrital zircon age components, confirming that most Kaweka samples have a Middle Jurassic detrital zircon age peak, whilst Pahau-Waioeka samples are strongly unimodal at c. 125 Ma. Kear & Mortimer (2003) In the Torlesse dataset (Fig. 6A), there is still an apparent to admittedly sparse fossil localities.…”

Sr ratios (at metamorphism) and detrital zircon patterns that in part are transitional between Rakaia and Pahau Terrane rocks and in part similar to Waipapa Terrane rocks. Combined detrital zircon age data for all Torlesse and Waipapa Terrane data reveal an essential unity, with a long persistence (260-120 Ma) of predominant Permian-Triassic sources in the form of a major Cordilleran-style batholith, a decline in major early Paleozoic-Precambrian sources between 260 and 220 Ma, and presence of minor Early Carboniferous to Late Devonian sources between 180 and 120 Ma. Rb-Sr and K-Ar ages indicate latest Triassic to Early Cretaceous metamorphism in an evolving accretionary wedge.

“…Australobuchia wherowhero is the earliest member of the genus to appear in Murihiku Terrane rocks that have been included in the Waipa Supergroup by Kear & Mortimer (2003), apart from a few very poorly preserved bivalves in slightly older beds that may be congeneric (Fleming & Kear 1960). Its range constitutes the A. wherowhero Zone some 200 m thick in Puaroan (middle Tithonian) rocks of the Murihiku Terrane straddling the Mangaoran/Waikatoan boundary, from Port Waikato to Kawhia.…”

“…However, some authors have also treated New Zealand Jurassic sedimentary rocks as fragments of once much larger and potentially interconnected basins (Cook et al 1999a,b;Tulloch et al 1999;kear & Mortimer 2003;Uruski et al 2003;Uruski & Baillie 2004). in this scenario, Jurassic strata of the Murihiku Terrane extend beyond the traditionally accepted terrane boundaries to trangress east into adjacent Waipapa Terrane (Morrinsville facies) and Brook Street Terrane (Barretts Formation) and west into Median Batholith enclaves such as Paterson Group, Largs Group, Rainy River Conglomerate, and Drumduan Group (see Mortimer et al 1999 for details).…”

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.
