Clay minerals detected on Mars are valuable targets to seek traces of life on the planet, where biosignatures might be preserved. Here, we report an in-depth spectral analysis of clay-rich outcrops identified in northern Xanthe Terra (300°-320° E, 10°-20° N). We focused particularly on the absorptions centered in the 1.0-2.6 µm spectral rang…
