Episodic construction of the early Andean Cordillera unravelled by zircon petrochronology [PDF]
Nature Communications, 2021 Episodic magmatism of the early Andes is the result of a complex interplay between mantle, crust, slab and sediment contributions that can be traced using zircon chemistry.

Petrochronology and hygrochronology of tectono-metamorphic events [PDF]
Gondwana Research, 2019 U-Th-Pb petrochronology is based on the incontrovertible fact that the diffusion of radiogenic Pb is negligibly small relative to retrograde reaction rates.

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 ...

Age of the magma chamber and its physicochemical state under Elbrus Greater Caucasus, Russia using zircon petrochronology and modeling insights [PDF]
Scientific Reports, 2023 Mount Elbrus, Europe's tallest and largely glaciated volcano, is made of silicic lavas and is known for Holocene eruptions, but the size and state of its magma chamber remain poorly constrained.

Accessory Mineral Eu Anomalies in Suprasolidus Rocks: Beyond Feldspar [PDF]
Geochemistry, Geophysics, Geosystems, 2020 Accessory mineral Eu anomalies (Eu/Eu*) are routinely measured to infer changes in the amount of feldspar over time, allowing accessory mineral U‐Pb dates to be linked to the progressive crystallization of igneous and metamorphic rocks and, by extension,

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 ...
