Scientific paper

Carbonate minerals are germane to questions involving volatile and climate history on Mars [e.g., 1,2]. Spectral observations provide evidence for the presence of carbonates in the Martian environment [1, 3-7]. Carbonate minerals are identified in Asian [8] and Saharan dust [9-11]. The imaginary index of refraction in the visible to mid-infrared wavelengths (vmir) of has been determined from a few of the many studies of carbonates spanning over 100 years [12-16]. The growing evidence for carbonates on Mars, the presence of carbonates in terrestrial aerosols, and the disagreement among the optical constants for these materials in the vmir has motivated a broader effort to determine the optical constants of carbonates [17-18]. The results of the application of the techniques described in [19] to estimate the optical constants of calcite will be presented.
