High spatial and spectral resolution refl ectance data acquired by the Mars Reconnaissance Orbiter Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument reveal the presence of H2Oand SiOH-bearing phases on the Martian surface. The spectra are most consistent with opaline silica and glass altered to various degrees, confi rming predictions based on geochemical experiments and models that amorphous silica should be a common weathering product of the basaltic Martian crust. These… CONTINUE READING
