The Bunger Hills: 60 years of geological and geophysical research
Autor: Naomi M. Tucker, Chris D. Clark, Martin Hand
Publikováno v: Antarctic Science. 32:85-106
Correlation of Rodinian and Gondwanan crustal domains relies on a thorough knowledge of those vestiges preserved today. The Bunger Hills hold a critical place in East Antarctica, recording the Mesoproterozoic assembly of Australo-Antarctica in Rodini

Granites and gabbros at the dawn of a coherent Australian continent
Autor: Laura J. Morrissey, Justin L. Payne, Lisa K. Roche, Naomi M. Tucker, Michael Szpunar, Regis Neroni
The Rudall Province in Western Australia is a key crustal component in the amalgamation of the Rodinia supercontinent. New field observations, U–Pb zircon geochronology and geochemistry identify three previously unrecognised Mesoproterozoic magmati

Further evidence for two metamorphic events in the Mawson Continent
Autor: Laura J. Morrissey, Naomi M. Tucker, Megan A. Williams, Tom Raimondo, Rian Dutch, Martin Hand, David E. Kelsey
Publikováno v: Antarctic Science. 30:44-65
In this study,in situand erratic samples from George V Coast (East Antarctica) and southern Eyre Peninsula (Australia) have been used to characterize the microstructural, pressure–temperature and geochronological record of upper amphibolite and gra

New constraints on metamorphism in the Highjump Archipelago, East Antarctica
Autor: Naomi M. Tucker, Martin Hand
Publikováno v: Antarctic Science. 28:487-503
The age and conditions of metamorphism in the Highjump Archipelago, East Antarctica, are investigated using samples collected during the 1986 Australian Antarctic expedition to the Bunger Hills–Denman Glacier region. In situ U-Pb dating of monazite

A tripartite approach to unearthing the duration of high temperature conditions versus peak metamorphism: An example from the Bunger Hills, East Antarctica
Autor: Justin L. Payne, Naomi M. Tucker, Chris D. Clark, David E. Kelsey, Martin Hand, Richard J.M. Taylor
We present LA-ICP-MS U-Pb monazite and zircon geochronology, trace element chemistry and phase equilibria forward modelling to constrain the P-T-t evolution of the Bunger Hills, East Antarctica. Metasedimentary rocks in the Bunger Hills record eviden

Genesis of the Archean-paleoproterozoic tabletop domain, Rudall Province, and its endemic relationship to the West Australian Craton
Autor: Michael Szpunar, Justin L. Payne, Laura J. Morrissey, Naomi M. Tucker
The Tabletop Domain of the Rudall Province has been long thought an exotic entity to the West Australian Craton. Recent re-evaluation of this interpretation suggests otherwise, but is founded on limited data. This study presents the first comprehensi

Phase equilibria modelling constraints on P-T conditions during fluid catalysed conversion of granulite to eclogite in the Bergen Arcs, Norway
Autor: Laura J. Morrissey, Kamini Bhowany, Steven M. Reddy, Mark A. Pearce, David E. Kelsey, Martin Hand, Chris D. Clark, Naomi M. Tucker
Exhumed eclogitic crust is rare and exposures that preserve both protoliths and altered domains are limited around the world. Nominally anhydrous Neoproterozoic anorthositic granulites exposed on the island of Holsnoy, in the Bergen Arcs in western N

A duality of timescales: Short-lived ultrahigh temperature metamorphism preserving a long-lived monazite growth history in the Grenvillian Musgrave–Albany–Fraser Orogen
Autor: Rian Dutch, Martin Hand, David E. Kelsey, Naomi M. Tucker
Publikováno v: Precambrian Research. 264:204-234
In situ LA–ICP–MS U–Pb monazite geochronology from the eastern Musgrave Inlier, central Australia, suggests that high- T , suprasolidus conditions were maintained for >70 Myr during the Grenvillian (c. 1220–1140 Ma). Calculated phase equilibr

A rift-related origin for regional medium-pressure, high-temperature metamorphism
Autor: Justin L. Payne, Martin Hand, Naomi M. Tucker
Crustal-scale exhumation during the Alice Springs Orogeny (c. 450–320 Ma) in central Australia has exposed a region of medium-pressure, high-temperature metasedimentary and metabasic rocks that comprise the Harts Range Group (HRG). Similarities in
