Book ChapterDOI

Paired plutonic belts in convergent margins and the development of high Sr/Y magmatism: Peninsular Ranges Batholith of Baja California and Median Batholith of New Zealand

TL;DR: In this article, the authors proposed a model that involves underthrusting of the outboard LoSY arc base during shallowing subduction to a deeper, more continentalward position.
Journal ArticleDOI

Isotopic ages from the Nelson region of South Island New Zealand: crustal structure and definition of the Median Tectonic Zone

TL;DR: The median tectonic line (MTZ) is an extension of the original concept of the Median Tectonic Line put forth by Landis and Coombs (1967) as discussed by the authors, which is a series of dismembered Mesozoic volcanic-plutonic arc complexes that are sandwiched between terranes of the Western and Eastern provinces.
Journal ArticleDOI

Field and Geochemical Constraints on Mafic–Felsic Interactions, and Processes in High-level Arc Magma Chambers: an Example from the Halfmoon Pluton, New Zealand

TL;DR: The Halfmoon Pluton of Stewart Island, New Zealand as discussed by the authors provides direct evidence for a number of physico-chemical processes that operate at depth within active arc settings, including the development of mineral fabrics (e.g. aligned plagioclase and hornblende crystals) and alignment of mafic enclaves.
Journal ArticleDOI

Plutonic rocks of Western Fiordland, New Zealand: Field relations, geochemistry, correlation, and nomenclature

TL;DR: In this article, a comprehensive description of the plutonic rocks of western Fiordland between Breaksea and Sutherland Sounds is provided, which includes smaller bodies of Paleozoic and Cretaceous granitoid.
Journal ArticleDOI

Tempo of burial and exhumation within the deep roots of a magmatic arc, Fiordland, New Zealand

TL;DR: The U-Pb thermochronology of titanite, apatite, and rutile from a crustal profile through a Mesozoic magmatic arc in Fiordland, New Zealand, is used to constrain the timing and duration of significant vertical movements during arc construction and evolution as mentioned in this paper.
