Ionic radius is related to the valence of the ion - ions that have lost electrons (cations) are smaller than their neutral state, ions that have gained.

D2300, BD2500H2, BD1900_2 Carbonate Index Map (Viviano-Beck et al., 2014) Bluish or yellowish white region indicate Mg carbonates Red/magenta – Fe/Mg phyllosilicate Blue – other hydrated minerals (sulfates, clays, hydrated silica etc)

Identification of mineral based on carbonate index

Comparison with spectral library spectra Siderite Saponite

Future Plans Based on the experience gained from the exercise of Capri Chasma, similar mineralogical studies will be carried other interesting regions of Mars along with other high resolution datasets. Mineralogical maps will be prepared to better understand geological history of Mars.
