Overview of the Median Batholith, New Zealand: a new interpretation of the geology of the Median Tectonic Zone and adjacent rocks

TL;DR: More than 90% of the rocks in the Median Tectonic Zone are plutonic and can be included in part of a newly defined Carboniferous to Early Cretaceous, ca 10,200 km2 composite regional batholith as discussed by the authors.
Journal ArticleDOI

Zealandia: Earth’s Hidden Continent

TL;DR: The identification of Zealandia as a geological continent, rather than a collection of continental islands, fragments, and slices, more correctly represents the geology of this part of Earth.
Journal ArticleDOI

- 01 Dec 1989 - 
TL;DR: In the Westland-Nelson provinces of New Zealand, high grade metamorphic and granitic basement rocks showing mylonitic ductile deformation are juxtaposed beneath low-grade metasedimentary rocks and undeformed granites by uplift on low-angle detachment faults.
Journal ArticleDOI

Uranium‐lead zircon ages from the Median Tectonic Zone, New Zealand

TL;DR: The median tectonic zone (MTZ) of New Zealand is a generally north trending belt of Mesozoic subduction-related I-type plutonic, volcanic, and sedimentary rocks in South Island and Stewart Island that separates Permian strata of the Eastern Province Brook Street Terrane from lower to mid-Paleozoic Gondwana margin assemblages of the Western Province as discussed by the authors.
Journal ArticleDOI

High-level stratigraphic scheme for New Zealand rocks

TL;DR: This paper introduced 14 new high-level stratigraphic names to augment existing names and to hierarchically organize all of New Zealand's onland and offshore Cambrian-Holocene rocks and unconsolidated deposits.
