Argon loss during deformation of micas: constraints from laboratory deformation experiments

Autor: A. K. Kronenberg, W. J. Dunlap

Publikováno v: Contributions to Mineralogy and Petrology. 141:174-185

The role of internal deformation in resetting argon ages of micas has been investigated by measuring 40Ar/39Ar ratios of biotite and muscovite, before and after experimentally deforming them. Neither mica crushed cataclastically at room temperature o

Early Paleozoic orogenic collapse, tectonic stability, and late Paleozoic continental rifting revealed through thermochronology of K-feldspars, southern Norway

Autor: Haakon Fossen, W. J. Dunlap

Publikováno v: Tectonics. 17:604-620

Southern Norway was subjected to contractional orogenesis and subsequent extensional collapse during the early to middle Paleozoic when Baltica collided with Laurentia, resulting in the Caledonian Orogen. The largely unknown post-Caledonian Paleozoic

Thermomechanical evolution of a ductile duplex

Autor: Christian Teyssier, W. J. Dunlap, Greg Hirth

Publikováno v: Tectonics. 16:983-1000

The thermomechanical evolution of a midcrustal ductile duplex in central Australia has been reconstructed through space and time using 40Ar/39Ar thermochronology, flow stress estimates, cross-sectional restoration of dislocation creep microstructures

Autor: Nick Mortimer, W. J. Dunlap, Sandra McLaren

Publikováno v: Tectonics. 31

[1] New 40Ar/39Ar ages from detrital K-feldspars and metamorphic white micas from the Eastern Province terranes of New Zealand have been used to investigate the thermo-tectonic history of different parts of an exhumed Mesozoic forearc basin and accre

Timing of volatile and magma ascent in the formation of the Bajo de la Alumbrera porphyry Cu-Au deposit

Autor: Noel C. White, Peter W. Reiners, David R. Cooke, W. J. Dunlap, Charlotte M. Allen, Ian H. Campbell, Anthony C. Harris

Publikováno v: Mineral Deposit Research: Meeting the Global Challenge ISBN: 9783540279457

Dacitic rocks at the Bajo de la Alumbrera porphyry Cu-Au deposit (NW Argentina) preserve textures that suggest volatiles streamed upwards through intrusions temporally related to ore formation and hydrothermal alteration. There is evidence that volat
