Geological presrciption with UV

The purpose of the project is to find the presence of ancient water channels in desert. The methodology consists in finding a place that we assume to be a dry channel. The evaporite minerals (halite, gypsum, etc.) have the capacity to fluoresce when they are lighted by ultraviolet waves (long and short). The procedure will consist to collect samples of minerals along the dry channel and to reference and localize all of them with the GPS. The second part of the study will be the lighting of the sample with the UV light and test the minerals with hydrochloric acid (HCl) (for the Carbonates). When the samples are referenced as evaporitics or no, they are put in a map with the software ArcMap from the ESRI suite, ArcGIS. The result will be a map with all the samples which will delimit the rivers. With these results it will be possible set the presence of an ancient river
