Petrogenesis and Au-PGE distribution in continental peridotites from the Adamawa Plateau, Cameroon Volcanic Line: Insights from petrography and geochemistry

open access: yesResults in Earth Sciences
The main aim of this paper is to examine the petrogenetic processes controlling the distribution of gold and platinum group elements (Au-PGEs). Au-PGE contents were measured using NiS fire assay combined with inductively coupled plasma mass spectrometry.

Petrogenesis of late cenozoic collision volcanism in western Anatolia, Turkey [PDF]

open access: yes, 1998
Western Anatolia exhibits a record of almost all stages of a collision event and its related magmatic processes. Following an Eocene continent-arc collision, Western Anatolia region experienced a complete cycle of thickening and orogenic collapse.

Caractéristiques pétrographique, géochimique et structurale de la section crustale profonde de l'ophiolite d'Oman : implications pour la genèse des magmas et le fonctionnement des chambres magmatiques à l'aplomb d'un centre d'expansion océanique

open access: yes, 2011
Ce travail repose sur (1) une étude de terrain des cumulats lités de l'ophiolite d'Oman, notamment dans plusieurs massifs où cette unité restait largement inexplorée, (2) une étude pétrographique et géochimique (microsonde électronique et LA-ICP-MS) d ...

Three water sites in upper mantle olivine and the role of titanium in the water weakening mechanism

open access: yes
Infrared spectroscopy on synthetic olivines has established that there are at least four different mechanisms by which hydrogen is incorporated into the crystal structure.

Melting the Mantle

open access: yes, 1999
The stony part of the Earth is solid under normal conditions at the present day. Volcanism is the eruption of molten or partially molten rock, that is, magma.

Dissecting Pirtobrutinib Resistance in Mantle Cell Lymphoma Through Single‐Cell Multi‐Omics

open access: yesAmerican Journal of Hematology, Volume 101, Issue 7, Page 1632-1649, July 2026.
ABSTRACT Pirtobrutinib (PBN), a non‐covalent BTK inhibitor, has been approved by the FDA for relapsed/refractory mantle cell lymphoma (MCL); however, resistance to PBN has been observed. To dissect the molecular dynamics driving PBN resistance, we performed integrative single‐cell multi‐omic profiling (scRNA‐seq, scATAC‐seq, and scDNA‐seq) on ...

Evolution of the continental upper mantle : numerical modelling of thermo-chemical convection including partial melting

open access: yes, 1999
This thesis elaborates on the evolution of the continental upper mantle based on numerical modelling results. The descriptive and explanatory basis is formed by a numerical thermo-chemical convection model.

Ridge Migration and Plate Boundary Readjustments at the Rodriguez Triple Junction

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Rodriguez Triple Junction (RTJ) marks the intersection of the Indian Ocean's three principal mid‐ocean ridges and is a type locality for Ridge‐Ridge‐Ridge triple junctions. A local seismic network was deployed for 8 months to monitor seismicity around the RTJ and the adjacent Central Indian Ridge (CIR).

Lithosphere‐Asthenosphere Interactions Across the Indo‐Burma Subduction Zone From Sp Receiver Functions

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Cenozoic convergence between the Indian and Asian plates has driven large‐scale mantle convection that interacts with both plates. Understanding this convergence benefits from clear imaging of the lithosphere‐asthenosphere boundary (LAB).

The complex networks of earth minerals and chemical elements

open access: yes, 2008
We study the large-scale organization of the mineral-mineral (MMN) and element-element (EEN) complex networks by analyzing their topological structures.
