Hi Everyone,
For those of you studying clays on Mars, asteroids or meteorites there are 2 sessions at the ICC meeting in Dublin this summer that could be of interest. July 13-18th at Trinity College.
Please consider submitting abstract in the coming weeks - the final date for abstract submissions is April 11th.
We look forward to engaging presentations and discussions with you at the ICC!

Session 2: Phyllosilicates in Asteroids and Meteorites: Identification and Characterization of Phyllosilicate Assemblages
https://icc.aipea.org/icc-02/
Phyllosilicates have been identified and characterized on the asteroids Ryugu, Bennu, and the dwarf planet Ceres through spectroscopic remote sensing and further investigated in the lab for Ryugu and Bennu. Characterization of phyllosilicates in meteorites also provides key constraints on understanding the phyllosilicates in asteroids. NH4-phyllosilicates have been identified across much of the surface of Ceres, and lab studies of potential forms of these clays are enabling a more accurate understanding of the types and chemistries of these intriguing materials. Lab measurements performed on Ryugu and Bennu returned samples demonstrate the presence of Mg-rich phyllosilicates, often associated with carbonates and organic components. Remote sensing at Ceres has revealed the presence of NH4-related spectral signatures, carbonates, and organics, often associated with phyllosilicates, highlighting an intriguing formation pathway. Abstracts are requested characterizing phyllosilicates in asteroids and meteorites, as well as lab studies supporting our understanding of these data.
Session 11: Identification and Characterization of Phyllosilicates on Mars through Remote Sensing, Rover Instruments, and Analog Studies
https://icc.aipea.org/icc-11/
Phyllosilicates are significant markers of aqueous alteration on Mars, providing key information for constraining the ancient geochemical history of that planet. This session aims to discuss advancements in understanding martian phyllosilicate assemblages through investigations of orbital remote sensing, analyses of rover instrument data, and studies of terrestrial analog materials containing phyllosilicates. Smectites and other clay minerals are observed in a variety of locations on Mars, frequently associated with sulfates, iron oxides/hydroxides, or carbonates. Investigating these sites through orbital and surface missions provides information on the geochemical environments present during their formation and potential indicators of past habitability. Studies of phyllosilicates on Mars using orbital or rover data, geochemical modelling, and characterization of clay-bearing analogs or martian meteorites are encouraged. By integrating these methods, the session aims to deepen our understanding of the conditions that shaped clay mineral assemblages and their implications for Mars' habitability.
