Zircon inheritance from long-lived sources of Late Triassic post-orogenic plutons, High Andes, Central Chile (similar to 30 degrees S): Magmatic feedbacks and petrogenetic implications
(Elsevier, 2020)
A comprehensive understanding of the magmatic system evolution and petrogenetic environment is crucial for the correct interpretation of magmatic zircon age spectra. In the Central Andes, a protracted Late Paleozoic period ...
Space-time relation of post-collisional granitic magmatism in Santa Catarina, southern Brazil: U-Pb LA-MC-ICP-MS zircon geochronology of coeval mafic-felsic magmatism related to the Major Gercino Shear Zone
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
LA-MC-ICP-MS U-Pb zircon dating was performed on syntectonic, early post-collisional granitic and associated mafic rocks that are intrusive in the Brusque Metamorphic Complex and in the Florianopolis Batholith, major ...
Zircon recycling and crystallization during formation of chromite- and Ni-arsenide ores in the subcontinental lithospheric mantle (Serrania de Ronda, Spain)
(Elsevier, 2017)
The ultramafic massifs of the Serrania de Ronda (namely Ronda, Ojen and Carratraca) are portions of Proterozoic (similar to 1.2-1.8 Ga) subcontinental lithospheric mantle (SCLM) affected by partial melting and infiltration ...
Lu-Hf ratios of crustal rocks and their bearing on zircon Hf isotope model ages: The effects of accessories
(Elsevier Science, 2018-05)
All other factors being equal, the calculation of zircon Hf two stage model ages (T DM Hf) depends on the particular Lu/Hf value assumed for the magmatic source, the effect being more pronounced as the age difference between ...
3.65–2.10 Ga history of crust formation from zircon geochronology and isotope geochemistry of the Quijingue and Euclides plutons, Serrinha nucleus, Brazil
(2008)
The Serrinha nucleus is one of the Archaean granite-gneiss terrains of São Francisco craton, Brazil. In this area, many granitic rocks formed during the Trans-Amazonian orogeny, and intruded during and
following a greenschist ...
Determination of crustal anatexis conditions from thermodynamic modelling and zircon data: the case of the late triassic a And S-Type granites in the high Andes of Central Chile (~30°S)
(Universidad de Chile, 2022)
This thesis is focalized in the thermodynamic conditions that favor the generation of anatectic melts in different scenarios, and also as a study case, about the origin of crust-related plutons of the Late Triassic, in the ...
A combined zircon Hf isotope and whole-rock Nd and Sr isotopes study of Carboniferous A-type granites, Sierras Pampeanas of Argentina
(Pergamon-Elsevier Science Ltd, 2020-06)
We report new whole-rock Nd and Sr isotope data for two strongly peraluminous and one slightly peraluminous Carboniferous A-type granitic plutons in the eastern Sierras Pampeanas of Argentina. Our study also integrates ...
