Article
Full-text available
Xenoliths brought up by kimberlite magmas are rare samples of otherwise inaccessible lithospheric mantle. Eclogite xenoliths are found in most cratons and commonly show a range of mineral and chemical compositions that can be used to better understand craton formation. This study focuses on five new kyanite-bearing eclogites from the Udachnaya kimb...
Article
Full-text available
Mantle eclogites are commonly accepted as evidence for ancient altered subducted oceanic crust preserved in the subcon-tinental lithospheric mantle (SCLM), yet the mechanism and extent of crustal recycling in the Archaean remains poorly constrained. In this study, we focus on the petrological and geochemical characteristics of 58 eclogite xenoliths...

Open access: https://doi.org/10.1038/s41467-020-17442-8 Trace amounts of water dissolved in minerals affect density, viscosity and melting behaviour of the Earth’s mantle and play an important role in global tectonics, magmatism and volatile cycle. Water concentrations and the ratios of hydrogen isotopes in the mantle give insight into these proces...
Article
Full-text available
A significant portion of the Earth’s water is found at trace levels in nominally anhydrous rock forming minerals in the crust and mantle. Its distribution has far-reaching implications in melt-generating processes, mantle rheology and the stability of the lithosphere. We report petrographic, major and trace element, Fourier transform infrared spect...
Thesis
Cette étude est basée sur la collection la plus complète d'éclogites cratoniques (> 180 nodules), provenant des cratons sibériens et sud-africains.Les éclogites non-métasomatisés de type IIA sont plus magnésiennes, enrichis en LREE, avec des valeurs de δ18O, de 3,7-7,5 ‰, des anomalies positives en Sr et correspondant à une couche à basse pression-...
Conference Paper
Full-text available
The origin of mantle eclogites is under constant debate, and most often interpreted as derived from a subducted oceanic crust. The present study focuses on the petrological and geochemical characteristics of a widely sampled suite of eclogite xenoliths from Roberts Victor Mine, South Africa. Non-metasomatised samples are preserved in the lowermost...
Thesis
For better understanding the PT conditions of the metamorphism engaged in the Variscan orogeny from the Southern Carpathians, but also a possible starting point for establishing a more accurate age of the similar bodies throughout the area,the study revolves around the retrograde mineral reactions. Although eclogite occurrences have been the subjec...
Conference Paper
One of the main concerns from nowadays regards environmental protection, however industrial and energetic demands cannot be left unsatisfied. In this social and economic context, mining waste deposits are a big problem which solving is imperative because of its great impact upon the society. The purpose of this paper is to optimize the quality of t...

Project
This project combines oxygen, hydrogen and lithium isotopes with 'water' analyses in eclogite xenoliths, to investigate early crustal recycling and associated water incorporation and preservation in upper mantle nominally anhydrous minerals (NAMs).
