Episodic construction of the early Andean Cordillera unravelled by zircon petrochronology. [PDF]
Nat Commun, 2021 AbstractThe subduction of oceanic plates beneath continental lithosphere is responsible for continental growth and recycling of oceanic crust, promoting the formation of Cordilleran arcs. However, the processes that control the evolution of these Cordilleran orogenic belts, particularly during their early stages of formation, have not been fully ...

Petrochronology and hygrochronology of tectono-metamorphic events [PDF]
Gondwana Research, 2019 Abstract U-Th-Pb petrochronology is based on the incontrovertible fact that the diffusion of radiogenic Pb is negligibly small relative to retrograde reaction rates. Multi-element maps demonstrate that patchy textures tightly correspond to (U + Th)-Pb age variations, requiring that fluid-induced dissolution/ reprecipitation is the principal cause of ...

Phase Relations, Reaction Sequences and Petrochronology [PDF]
Reviews in Mineralogy and Geochemistry, 2017 At the core of petrochronology is the relationship between geochronology and the petrological evolution of major mineral assemblages. The focus of this chapter is on outlining some of the available strategies to link inferred reaction sequences and microstructures in metamorphic rocks to the ages obtained from geochronology of accessory minerals and ...

Petrochronology of polygenetic white micas (Naxos, Greece) [PDF]
Journal of Metamorphic Geology, 2022 AbstractNaxos in the Greek Cyclades preserves a type example of polymetamorphism. The southern and northern parts of the island record different Tertiary P–T histories between Eocene and Miocene times, including a blueschist facies event, one or more amphibolite/greenschist facies overprint(s) and contact metamorphism. Age attributions for these events

Developing an inverted Barrovian sequence; insights from monazite petrochronology [PDF]
Earth and Planetary Science Letters, 2014 AbstractIn the Himalayan region of Sikkim, the well-developed inverted metamorphic sequence of the Main Central Thrust (MCT) zone is folded, thus exposing several transects through the structure that reached similar metamorphic grades at different times.

Monazite Microstructures and Their Interpretation in Petrochronology [PDF]
Frontiers in Earth Science, 2021 The phosphate mineral monazite (LREE,Y,Th,Ca,Si)PO4 occurs as an accessory phase in peraluminous granites and Ca-poor meta-psammopelites. Due to negligible common Pb and very low Pb diffusion rates at high temperatures, monazite has received increasing attention in geochronology.

A zircon petrochronologic view on granitoids and continental evolution
Earth and Planetary Science Letters, 2020 Abstract Temporal trends in granitoid chemistry and thermometry constrain major global changes in magmatism, tectonism or crustal thickness in the continents. Our study relies on zircon geochronology and trace element geochemistry on four new detrital rocks (two modern sediments and two Archean metasedimentary rocks) and a global compilation of ...

High-P metamorphism in the Mesoproterozoic: Petrochronological insights from the Grenville Province
Precambrian Research, 2023 In the Grenville Province, high-P rocks that are discontinuously exposed along the margin of the allochthonous belt preserve the record of deep crustal processes and are an essential puzzle piece to understanding Mesoproterozoic geodynamics. The Manicouagan Imbricate zone (MIZ) is one of the three high-P domains from the Grenville Province.
