An African origin for the fine dust found in European loess during the Last Glacial Maximum
AGU 2024
paleoceanography and paleoclimatology | 09 december 2024
Denis-Didier Rousseau, Catherine Chauvel, Peter O....
The intensification of the dust cycle during the last glacial maximum persists as a significant challenge to our understanding of Earth's systems and ...

Survival of Hadean depleted material in present-day mantle
AGU 2024
volcanology, geochemistry and petrology | 09 december 2024
Catherine Chauvel, James Badro, Claudine Israel, P...
Intraplate volcanism provides a remarkable insight into the mantle internal structure. Its source can be shallow but also as deep as the core-mantle b...

EXPLORING EARTH’S EVOLUTION: THE HADEAN THROUGH THE PRESENT II ORAL
study of earth's deep interior | 14 december 2023
Baptiste Thomas, Henri Samuel, cinzia G. farnetani...
During the accretion stage, giant impacts released enough energy to melt the entire mantle, so that the Earth underwent at least one magma ocean stage...

Earth's mantle composition revealed by mantle plumes, geochemical and geodynamic perspectives. Where are we now, and where are we going?
CHEMISTRY AND EVOLUTION OF EARTH’S INTERIOR AS RECORDED BY MANTLE PLUMES II ORAL
volcanology, geochemistry and petrology | 13 december 2023
Dominique Weis, Karen S. Harpp, Lauren Harrison, M...
Mantle plumes can originate at depths near the coremantle boundary, ~2,800 km, providing invaluable information about the composition of the deep mant...

Two different dust transports built European loess deposits at the Last Glacial Maximum
ATMOSPHERIC AEROSOLS AND THEIR INTERACTIONS WITH CLOUDS, RADIATION, AND CLIMATE I ORAL
atmospheric sciences | 13 december 2023
Denis-Didier Rousseau, Catherine Chauvel, Peter O....
For a long time, loess deposits have been interpreted as a result of a schematic model that associates two main dust transports: one over short distan...

Fani Maoré, a New “Young HIMU” Volcano with Extreme Geochemistry
CHEMISTRY AND EVOLUTION OF EARTH’S INTERIOR AS RECORDED BY MANTLE PLUMES II ORAL
volcanology, geochemistry and petrology | 13 december 2023
Catherine Chauvel, Edward Inglis, Pamela Gutierrez...
Intraplate volcanism provides a remarkable insight into diverse sources in the mantle because its source can be quite shallow, or as deep as the core-...

DUST IN A CHANGING CLIMATE: FROM SMALL‐SCALE INSIGHTS TO LARGE‐SCALE UNDERSTANDING III ORAL
atmospheric sciences | 16 december 2022
Denis-Didier Rousseau, Pierre Antoine, Catherine C...
The Last Climate Cycle (LCC, 130-15kyr) has shown cold, dusty (GS) and warmer, non-dusty (GI) intervals, when the atmosphere was 2-20 times more loade...
