Low-temperature thermochronometry reveals regional Late Cenozoic denudation in Fiordland, New Zealand, consistent with geodynamic models showing uplift of the overriding plate during incipient subduction. The data show a northward progression of exhumation in response to northward migration of the initiation of subduction. The locus of most recent uplift coincides with a large positive Bouguer gravity anomaly within Fiordland. Thermochronometrically deduced crustal thinning, anomalous gravity… 
Regional exhumation history of brittle crust during subduction initiation, Fiordland, southwest New Zealand, and implications for thermochronologic sampling and analysis strategies
We analyze spatial trends and statistical properties of 410 apatite and zircon fission track and (U-Th)/He ages, and implement a weighted least-squares regression scheme to obtain the regional rock
Uplift and exhumation in Haida Gwaii driven by terrane translation and transpression along the southern Queen Charlotte fault, Canada
The mountainous archipelago of Haida Gwaii abuts the transpressive Pacific–North American plate margin north of the Cascadia subduction zone (northwestern North America). Topography on Haida Gwaii
Thermo-tectonic studies of Mesozoic basement rocks, North Island, New Zealand
The basement rocks of North Island, New Zealand, comprise metasedimentary terranes that were accreted onto the eastern Gondwana margin during Mesozoic subduction. Since the Oligocene, these terranes
Miocene‐Recent deformation, surface elevation, and volcanic intrusion of the overriding plate during subduction initiation, offshore southern Fiordland, Puysegur margin, southwest New Zealand
Abstract We analyse results of dredge sampling, a high‐resolution seismic reflection survey, and unpublished petroleum industry data from part of the overriding continental plate of the Fiordland
In this thesis, I present structural and U/Pb geochronologic data on zircon from two deep-crustal shear zones exposed in Doubtful Sound, Fiordland, New Zealand. Fiordland is a unique setting where
Quaternary Tectonics of New Zealand
The New Zealand landmass exists because it straddles the active obliquely convergent Pacific-Australia plate boundary, which comprises the opposite-dipping Hikurangi and Fiordland subduction systems


Multigenetic gravity couple across a modern convergent margin: inheritance from Cretaceous asymmetric extension
SUMMARY Profiles of the pronounced gravity couple associated with the Puysegur margin in New Zealand suggest that the crust of the Fiordland block, which occupies the leading edge of the overriding
Inferred uplift rates from raised marine surfaces, southern Fiordland, New Zealand
Abstract Well-preserved remnants of a flight of raised marine benches can be recognised at altitudes of up to 1000 m above sea level in the extreme southwest of Fiordland. Radiocarbon-dated wood
The tectonic setting of the Fiordland region, south-west New Zealand
Summary. The Indian/Pacific plate boundary to the south-west of New Zealand has undergone highly oblique compression during the past 15 Myr. Subduction of the Indian plate north-eastwards under the
A complex, young subduction zone imaged by three-dimensional seismic velocity, Fiordland, New Zealand
SUMMARY The Fiordland subduction zone, where subduction developed in the late Miocene, has been imaged with P and S‐P arrival-time data from 311 earthquakes in a simultaneous inversion for
Dynamics of subduction initiation at preexisting fault zones
We show that a new subduction zone can initiate at a preexisting dipping fault zone with reasonable plate forces, consistent with what is observed in the western Pacific. The dynamics of subduction
Abrupt strike‐slip fault to subduction transition: The Alpine Fault‐Puysegur Trench connection, New Zealand
Swath bathymetry and other geophysical data collected over the Fiordland Margin, southwest of New Zealand are used to investigate the mechanism of transform‐subduction transition between the Alpine
Focal mechanisms of large earthquakes in the South Island of New Zealand: implications for the accommodation of Pacific‐Australia plate motion
b The plate motion model NUVEL-1 predicts oblique convergence between the Pacific and Australian plates in the South Island of New Zealand. We used P and SH body waveform analysis to constrain
Fracture zone subduction and reactivation across the Puysegur ridge/trench system, southern New Zealand
A two-dimentional kinematic model for lithospheric thrusting that considers the flexural interaction between the underriding and overriding plates was used to assess the mechanical implications of
Horizontal lithosphere compression and subduction: Constraints provided by physical modeling
Physical modeling of the subduction is performed with a two-layered mantle model (elastico-plastic lithosphere and low-viscosity asthenosphere) and is governed by the criteria of similarity.
Marine terraces of the Waitutu district and their relation to the late Cenozoic tectonics of the southern Fiordland region, New Zealand
Abstract At least 13 marine terraces or their remnants, with maximum shoreline altitudes of c. 3 m, 60, 90, 140, 230, 320, 370, 460, 580, 660, 780, 870 and 1040 m, are preserved in the Waitutu
