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.

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.

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 ...

Deeply subducted continental fragments – Part 2: Insight from petrochronology in the central Sesia Zone (western Italian Alps) [PDF]
Solid Earth, 2018 Subducted continental terranes commonly comprise an assembly of subunits that reflect the different tectono-metamorphic histories they experienced in the subduction zone.

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,

Petrochronology of polygenetic white micas (Naxos, Greece) [PDF]
Journal of Metamorphic Geology, 2022 Naxos 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/

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.
