Cette étude donne un nouvel aperçu des minéralisations à métaux de base pouvant contenir des concentrations en métaux critiques comme le germanium associé à la sphalérite, dans la Zone Axiale des Pyrénées. La caractérisation de ces minér

Away from tectonically active regions, the continental crust has an average thickness of 40 ± 1 km. Yet, it shows a remarkable variability from 25 to 65 km, comparable to that of the most tectonically active regions. Here, we consider the problem of

How high to ultra-high temperature terranes form

Autor: Bénédicte Cenki-Tok, Patrice Rey, Diane Arcay

Long-lived high- to ultra-high temperature (HT-UHT) terranes formed mostly during the Paleo-Proterozoic and are often associated to supercontinent cycles. Yet the detailed processes and conditions involved in their formation remain largely unresolved

Intra-oceanic subduction initiation recorded by the metamorphic sole of the New Caledonia ophiolite: petrological, structural and age constraints

Autor: Derya Gürer, Julien Collot, Pierre Maurizot, Bénédicte Cenki-Tok, Vasileios Chatzaras, Fernando Corfu

Subduction initiation is commonly identified as a major enigma in plate tectonics. Attention to subduction initiation is growing in the community, as is our understanding of the sequences of geologic events that precede and postdate this critical sta

International audience; In the Dent Blanche Tectonic System, the Mont Morion biotite-bearing granite is a km-scale intrusion preserved in a low-strain volume. Zircon saturation thermometry suggests that it crystallised from a melt that reached about
