Sulfites and Sulfates Formed by Weathering of Early Martian Carbonates in a Sulfur Dioxide-Bearing Atmosphere

<p>This data package contains the X-Ray diffraction (XRD) and infrared reflectance data acquired on the samples of carbonates altered in SO2/H2O or SO2/H2O/H2O2 atmospheres (pressure 0.8 bar, temperature 25C). The package also included pictures of the samples after alteration in the two simulated atmospheres.&nbsp;</p>
