The influence of rotation on the preservation of heterogeneities in magma oceans.
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...

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...

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...

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...

Mixing Time of Geochemical Heterogeneities in a Vigorously Convecting and Rapidly Rotating Terrestrial Magma Ocean.
ACCRETION AND DIFFERENTIATION OF ROCKY PLANETS FROM INTERDISCIPLINARY PERSPECTIVES III POSTER
study of earth's deep interior | 14 december 2022
Baptiste Thomas, Henri Samuel, cinzia G. farnetani...
The recent discovery that several hotspots (Hawaii, Samoa, Iceland and Galápagos) exhibit a negative µ182W value [1] poses first-order quest...

What mantle plumes tell us about the Earth
NORMAN L. BOWEN AWARD LECTURE I
volcanology, geochemistry and petrology | 15 december 2021
Catherine Chauvel
The Earth is an active planet that has permanently evolved since its accretion. After core formation, the mantle and crust differentiated, and at some...
