Subduction regression of volcanism in New Zealand

Volcanism and freshwater fish biogeography in the northeastern North Island of New Zealand

Major volcanic eruptions in the central North river systems by dispersing through the sea. However, some Island of New Zealand and, in particular, an eruption dated rivers, that were probably severely affected in their at  186, spread ignimbrite and volcanic ashes (tephra) headwaters, have lower elevation and more distant over a broad area, deposition of which caused major tributaries whose c...

New Zealand: dating the transition between volcanism in the Coromandel Arc and the Taupo Volcanic Zone

Subduction-related volcanism in the northern part of the North Island of New Zealand shifted abruptly during the late Pliocene. This study focuses on the transition, in time and space, from the NNW-oriented Miocene–Pliocene Coromandel Volcanic Zone to the northeast-oriented active Taupo Volcanic Zone. The volcanic rocks marking this transition are exposed in the Tauranga Basin and adjacent Kaim...

Polynesian settlement of New Zealand and the impacts of volcanism on early Maori society: an update

Models of settlement Various lines of evidence indicate that the ‘homeland’, or Hawaiiki, of the early Polynesian settlers of Aotearoa was eastern Polynesia (e.g. see Sutton, 1994; Howe, 2003). Establishing the timing of settlement has been problematic, however. The most recent and reliable evidence, both from archaeological and natural sites, points consistently to initial settlement between c...

Extension and Partitioning in an Oblique Subduction Zone, New Zealand: Constraints from Three-Dimensional Numerical Modeling

Uplift in the Fiordland region, New Zealand: implications for incipient subduction.

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 ...
