Result of hydroxyl-bearing and carbonate minerals and iron oxides extracted by using Crosta technique and 4 scene anomaly-overlaying selection.
The geochemical anomalies were overlaid on the remote sensing image for synthetic analysis. The map was generated using ArcMap v10.2 (http://www.esri.com/software/arcgis/arcgis-for-desktop) on the basis of TM and ETM+ data courtesy of the U.S. Geological Survey (http://landsat.usgs.gov).
