| Abstract | The district scale potential of the area in Savannakhet province, south-eastern Laos was first recognized in 1990 to have some gold and copper occurrences. The geologic features indicative of this gold and copper mineralisation in the area are intrusive centers that have been the focus of intense hydrothermal activity with large scale alteration and apparent metal zonation controlled by adjacent structures plumbing systems. Four broad alteration/mineralization styles are recognized, quartz stockwork porphyry Mo, Cu-Au skarn, Cu-Au carbonate replacement, and sediment-hosted Au. The gold and copper potential of the study area is assessed by mains of integration geophysical and geochemical database by using GIS techniques for generating to indicate map of gold and copper deposits on the study area. This research study deals with the integration of multiple spatial datasets to map for the gold and copper potential of deposit in study area. The following steps were carried out in order to achieve the objectives of the research study and namely, (i), input spatial databases into a Geographic Information System (GIS); (ii), data processing to extract multi-sources indicators of airborne magnetics/aeromagnetic, gravity and IP anomaly from geophysical data and observation of relationship between spatial information; (iii), to interpolate anomaly of mineral deposits from geochemical attributes at location of known gold and copper deposit occurrences were determined from rock outcrop, soil sampling and drill hole geochemical data on the study area; (iv), to observe relationship between geophysical anomalies and geology units and mineral deposit occurrences from geochemical data; (v), to interpret and integrate map to indicate gold and copper deposits of prospectively location on study area. The overall results of this study could show (a) the usefulness of applying GIS techniques to integrate geophysical and geochemical data for re-classification of the mineral deposit occurrences and (b) the usefulness of spatial data integration in gold and copper prospectivity mapping on study area. |
