Title: Examination of 24 Martian rock and soil classes using GUAPX software and the K-value approach on MER-A APXS results for possible hydration or ALICs
Author: Kedia, Ramita
Abstract: Paso Robles soil class is proven to be significantly hydrated (Campbell et al., 2008). Numerous other Martian soil and rock classes identified by MER-A APXS have not been previously examined for the presence of possible ALICs. The goal of this project was to detect the possible presence of ALICs in a group of selected classes using experimental C/R values obtained from GUAPX software and by employing the comprehensive K-value analytical technique. K -values for Gertrude Weise and Elizabeth Mahon classes were significantly lower that the calibration standard average K-value of 0.91. K-values for all other classes were within or higher than the K-value average zone (0.87-0.95). The GUAPX plots were insufficient in detecting the presence of possible ALICs. The K-value results indicated that rock class Elizabeth Mahon and soil class Gertrude Weise contained possible ALICs in orders of magnitude similar to Paso Robles which contains 6-18 wt% hydration (Campbell et al., 2008). All other rock and soil classes analysed failed to reveal possible ALICs in the K-value plots. The levels of ALICs in these classes may be below the detection limit or they may not contain mineralogically bound water despite the role of past aqueous alterations in their formation.
