MINERAL POTENTIAL EVALUATION FOR OLYMPIC DAM-KIRUNA DEPOSITS IN THE MANITOU AREA, GRENVILLE PROVINCE, QUEBEC: SYSTEMATIC MODELING OF GEOLOGICAL DATA BY GRID ANALYSIS
Geologie Quebec has developed a new tool that allows the systematic evaluation, for a specific metallogenic model, the mineral potential of a map area on a reconnaissance or regional scale. This tool is a GIS-based database system called SPCPM, which uses a knowledge-driven approach to integrate through an additive process all the geological parameters pertinent to the model. SPCPM systematizes the various steps needed for the evaluation, such as database extraction, conversion of geological elements from vectorial to grid format, application of a subjective weighting procedure to each data set, spatial treatment of adjacent areas of favorability, and overlay combination. A color scheme specific to the model is applied to the resulting map to illustrate relative favorability.
