Crustal evolution of Western Europe: Constraints from detrital zircon U-Pb-Hf-O isotopes

Zircon U‐Pb‐He Double Dating of Modern Sands From the Inn River Catchment: Assessing Resolution and Potential in a Complex Orogenic Setting

“…Further significant age groups clustered around 450 Ma (mostly in TWR, UPI, and INN), 600 Ma, and 1,000 Ma (mostly in ÖTZ, UPI, and INN). Major Mesoproterozoic zircon-forming igneous events known from the European crust (e.g., Avigad et al, 2022) are also seen in the cumulative plot (Figure 4b).…”

Early Paleozoic Cenerian (Sardic) geodynamic relationships of peripheral eastern north Gondwana affinities: revisiting the Ordovician of the Getic/Kučaj nappe (eastern Serbia)

Geochemistry of metasedimentary rocks from the Eastern Pyrenees (Iberian Peninsula): Implications for correlation of Ediacaran terranes along the Gondwanan margin

“…The existence of episodic subduction along Gondwanan and proto-Gondwanan margins, facing the West Africa Craton, Tuareg Shield, Sahara Metacraton and surrounding areas since at least 750 to ca. 500 Ma, is widely accepted (e.g., Pereira et al, 2012;Díez Fernández et al, 2019;Arenas et al, 2021;Avigad et al, 2022;Rojo-Pérez et al, 2022;Moreno-Martín et al, In press). The sedimentary rocks generated along these margins were derived from recycling specific crustal areas, preserving valuable geochemical information useful in paleoreconstructions.…”
