“…Because both grains are close to concordia and/or are apparently not overgrown with significant zircon from the c. 101 Ma magma, these grains are likely to represent (detrital) zircons derived from the upper crustal rocks through which the magma was extruded, rather than the source rocks from which the rhyolitic magma was generated. These ages are consistent with derivation from sedimentary rocks similar to T420 (Cawood et al 1999), which have strong detrital populations at 200-280 and 460-550 Ma.…”

“…All samples are stored in the Auckland University rock collection. Isaac et al 1994;Mortimer 1995a;Cawood et al 1999). Vertical arrows indicate zircon FT ages for accumulation of Waioeka (125 + 2 Ma), Omaio (108 ± 6 Ma), and Pahau/Axial-B petrofacies (152+1 Ma) based on Kamp (1999).…”

“…There are further circumstances which do not favour model 3 as a likely scenario: (i) distinctive Zr-rich rhyolitic conglomerate clasts from Whanarua Bay, presumably sourced from the Houhora Volcanic Complex of northern North Island (Isaac et al 1994;Mortimer 1995a); (ii) U/Pb (SHRIMP) ages of detrital zircons from Whanarua Bay as young as c. 98 Ma (Cawood et al 1999); and (iii) the assumed sedimentary contact between Waioeka and Omaio petrofacies (Mortimer 1995a;Leverenz 1999). All these suggest that sedimentation of Waioeka and Omaio petrofacies had basically ceased before juxtaposition with the "western" Torlesse.…”
