20-EPN2-088: High spectral resolution / low-temperature IR study of carbonates.
Virtual visit by Simone De Angelis and Cristian Carli, IAPS-INAF(Italy), to TA2.8 CSS (Cold Surfaces Spectroscopy) at IPAG (France).
Dates of visit: 11 May – 04 June 2021
Report Summary: We planned to acquire reflectance spectra of anhydrous carbonates in the infrared range (3.2-4.6 μm), at high spectral sampling/resolution and at different cryogenic temperatures in the range 60-270K.
The analysed materials were calcite, dolomite, siderite, natrite, malachite and magnesite; all the minerals were prepared and measured at fine powders, d<50 μm. These measurements provide new spectral data in the IR that will be useful in the interpretation of remote-sensing spectroscopic observations of Solar System rocky bodies such as Mars, Jovian satellites and minor bodies by current and future missions (Mars 2020, ExoMars-2022, JUICE, Europa Clipper, OSIRIS-REx).
