What is The application of evidential belief function in the integration of regional geochemical and geological data over the Ife-Ilesha goldfield, Nigeria about?

Abst,ract-There are several methods available for the integration of geological, geophysical and even remotely sensed data sets. Several published reports have discussed the successful application of these integration techniques, including geologically orientated geographical information systems (GIS), to non-renewable resource exploration. Many geoscience data sets often have only partial coverage, and in most cases have different spatial resolution. These shortcomings plague statistical integration schemes employed in resource evaluation. In this paper, the evidential belief function approach is examined and applied to the integration of geological and geochemical data sets over the Ife-llesha goldfield, southwest Nigeria. In using this approach, nine maps of trace element concentrations (whole rock) and that of the bedrock geology of the test area were digitised. The characteristic grid values of the digitised maps were converted to degrees of belief, with a Au bearing mineral deposit as the target proposition. These resulting spatial data sets were pooled using the Dempster-Shafer combination rule. The resulting maps define portions of the study area with known auriferous miner
