In 1994 the QMAP 1:250 000 Geological Map of New Zealand project began with compilation of the Dunedin sheet. Nearly 18 years later, publication of the Hawke's Bay sheet marks the completion of all 21 maps. The adoption of geographic information systems (GIS) software for data capture, data management and map production has not only produced high cartographic quality maps, but also built the attribute-rich, nationally consistent QMAP GIS spatial database. The project cost about NZD $24M, and the results are now being used by government, industry and research organisations across infrastructure, geological hazard, resource and environmental areas. QMAP has added significantly to general knowledge of New Zealand's geological composition and history due to new discoveries and validation of concepts. Notable advances include work on the allochthons of Northland and East Coast; rationalisation of the Taupo Volcanic Zone and East Coast stratigraphic successions; differentiation of the Torlesse basement terranes; clarification of the transition from Otago Schist to Alpine Schist; determining the complex spatial and temporal history of igneous intrusions in Fiordland and Stewart Island; and mapping Quaternary sediments by oxygen isotope stage and depositional processes.

“…Component age peaks were determined and calculated from these diagrams, and their age errors calculated at 95% confidence limits. Following the selection protocols of Adams et al (2007), the age peaks are regarded as significant only where the number of individual zircon analyses in a group (denoted as n) is >3, and that group represents >4% of the total number (denoted as N) of the analysis set. The resulting component age data are summarised and listed by locality number in Table 3.…”

Thermal history and exhumation of basement rocks from Mesozoic to Cenozoic subduction cycles, central North Island, New Zealand

et al. 2014

A new thermochronological study of the basement rocks of the central North Island, New Zealand, records thermal and exhumation histories related to two subduction cycles since the latest Jurassic. The basement comprises metasedimentary terranes accreted onto eastern Gondwana during Mesozoic subduction. Since the Oligocene, these terranes have been located on the hanging wall of the Hikurangi subduction margin, overriding the Pacific Plate. Results of zircon fission track (121-264 Ma) analysis yield detrital or slightly reset ages; apatite fission track (19.8-122 Ma) and (U-Th-Sm)/He (10.3-95.2 Ma) ages are fully reset. Results from inverse thermal history modeling of the data of individual and stacked samples imply the following: (1) after their accretion, the basement rocks were cooled and exhumed to shallow depths of the crust in the Early Cretaceous (by~150-135 Ma). This was followed by an episode of reheating until~100 Ma, which we interpret to be the result of burial by sedimentation above the accretionary wedge during extensional deformation caused by continued underplating and thickening of the wedge from beneath. (2) From 100 Ma, our data indicate thermotectonic quiescence until the Oligocene (~27 Ma). (3) During initiation of the Hikurangi Margin, the fore-arc proto-Axial Ranges began to exhume during the late Oligocene to early Miocene (~27-20 Ma). Subduction-triggered unroofing removed~1.2-2.8 km of overburden, most of which was probably the less lithified passive margin sediments. (4) Along the western central North Island, the exhumational response to the Hikurangi subduction was limited, with a total magnitude of erosion <1.5 km in the Cenozoic.
