Geochronological challenges posed by continuously developing tectonometamorphic systems: insights from Rb–Sr mica ages from the Cycladic Blueschist Belt, Syros (Greece). [PDF]
, 2016 Is metamorphism and its causative tectonics best viewed as a series of punctuated events or as a continuum? This question is addressed through examination of the timing of exhumation of the Cycladic Blueschist Belt (CBB).

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.

Origin and evolution of the Variscan Léon eclogites: insights from zircon and garnet petrochronology [PDF]
European Journal of MineralogyEclogites record the deep burial and exhumation of crustal terranes, which are key tectonic markers in the evolution of orogenic belts. Unraveling the evolution of eclogites and eclogite-bearing terranes may nevertheless be challenging, especially in old

Variations in the P‐T‐t of Deformation in a Crustal‐Scale Shear Zone in Metagranite
Geochemistry, Geophysics, Geosystems, 2020 Deformation in crustal‐scale shear zones occurs over a range of pressure‐temperature‐time (P‐T‐t) conditions, both because they may be vertically extensive structures that simultaneously affect material from the lower crust to the surface, and because ...

Interpreting Europium Anomalies in Zircon: The Importance of Source Redox
Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.Abstract The sources of granitoids are variably oxidized due to the diversity of environments in which they form. This environmental and consequent chemical variability leads to differences in mineral assemblages, proportions, and compositions of ferric and ferrous iron‐bearing phases in these sources and in the resultant granitoids. Accessory minerals
