AbstractAeolian processes produce vast areas of sand and dunes in the arid region and need monitoring since they are encroaching land and degrading infrastructures. In this study, we used the satellite data of ASTER and mineral indices namely quartz index (QI) and carbonate index (CI), and identified and discriminated the sand deposits, dunes, and associated rock formations that occurred in and around the QAFCO site 5/6, Qatar. The mapping of the area using high spatial resolution WorldView-2 satellite data confirmed the presence of sand deposits, dunes, and sand encroachments in the site. Our field studies validated the satellite data results. The grain size analyses of samples showed that the deposits have predominantly sand grains (81.3 to 99.81 %). The XRD analyses of samples identified the presence of quartz, calcite, dolomite, albite, and halite minerals. These are confirmed by geochemical analyses, which showed the high concentration of SiO2, Al2O3, CaO, MgO, Na2O, CO3, SO4, Cl, and B. In addition, the study of sand stabilization by bacteria method to stop the erosion at selected places of the site showed the applicability of the technique. All results allowed us to assess the implications of the deposits and encroachments at the industry site.
