Mineralogy of Meteorites and Micrometeorites: Tracing Aqueous Alteration and Classification Across Parent BodiesThe mineralogy of meteorites records evidence of parent bodies second processes providing constraints on aqueous alteration and geochemical environments. This seminar will focus on the characterization of secondary mineral phases in carbonaceous chondrites and ungrouped chondrites, as well as Martian meteorites, in order to investigate the traces of aqueous alteration. In contrast, micrometeorites offer insights into the diversity of parent bodies and the flux of cosmic material to Earth through time. Using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and transmission electron microscopy (TEM), we analyze the mineralogy and petrography of meteorites and micrometeorites, identifying primary and secondary mineral phases to reconstruct parent body processes, assess post-atmospheric entry alteration, and refine current classification schemes.
"Advances in Reversible Deactivation Radical Polymerization and Emulsion-Templating Polymerization for Drug Delivery and Tissue Engineering Applications." Outgassing and atmosphere formation on terrestrial bodiesI will discuss the implications of early processes related to planet formation like 26Al heating and magma ocean outgassing on the volatile content and the atmospheric evolution of terrestrial planets Earth and Venus and exoplanets beyond our solar system.
L’intérieur des planètes telluriques révélé par les déformations de marées Tardi-magmatism or alteration: What do the iddingsite veins in the NWA 817 Nakhlite tell us about the Amazonian history of Mars?
