SHRIMP U-Pb zircon geochronology of the High Himalayan rocks in the Nyalam region, Tibet

Himalayan Journal of Sciences, 2008
FIGURE 1. Detrital zircon age spectra from Nyalam High Himalaya (Sample NY93-1) U-Pb age patterns of individual detrital zircons are a potentially powerful tool for constraining metasedimentary provenance. Each zircon grain has a characteristic age reflecting its genesis, and the overall population of detrital zircons represents the spectrum of primary

Petrology and SHRIMP U–Pb zircon geochronology of Cordilleran granitoids of the Bariloche area, Argentina

Journal of South American Earth Sciences, 2011
Abstract A petrological and geochronological study of Cordilleran granitoid intrusions in the Bariloche area (Argentina) point to a complex time-compositional evolution of magmatic processes in relation with oblique subduction of the Phoenix plate below the South America active margin during Jurassic times. The observed geochemical variations in both

Identifying granite sources by SHRIMP U-Pb zircon geochronology: an application to the Lachlan foldbelt

Contributions to Mineralogy and Petrology, 1999
The potential genetic link between granites and their host sediments can be assessed using zircon age inheritance patterns. In the Lachlan fold belt, southeastern Australia, granites and associated high-grade metasedimentary rocks intrude low-grade Ordovician country rock. This relationship is well-exposed in the Tallangatta region, northeast Victoria (

SHRIMP U‐Pb geochronology of Cretaceous magmatism in northwest Nelson‐Westland, South Island, New Zealand

New Zealand Journal of Geology and Geophysics, 1997
Abstract Ion microprobe U‐Pb zircon ages have been obtained from four samples of Cretaceous granitoid and two samples of volcanogenic sediment from the northwest Nelson‐Westland region of the South Island of New Zealand. Crow Granite, which intrudes lower Paleozoic metasedi‐mentary rocks in the Buller Terrane on the eastern side of the Karamea ...

Exploring for the Future SHRIMP geochronology of drillhole LBD2, Limbunya region, Northern Territory

Geoscience Australia’s Exploring for the Future (EFTF) program provides precompetitive information to inform decision-making by government, community and industry on the sustainable development of Australia's mineral, energy and groundwater resources. By gathering, analysing and interpreting new and existing precompetitive geoscience data and knowledge,

Identifying Cadomian events through SHRIMP geochronology: Ediacaran magmatism in the Peloritani Mountains (S Italy).

2009
Augen gneisses of debated origin and unknown protolith age form much of the Hercynian basement of the Peloritani Mountains of Sicily (Calabria-Peloritani Orogen). Petrogenetic studies based on field, petrographic and geochemical features have yielded inconclusive results.
