Proceedings of GeoComputation ‘97 & SIRC ‘97 Effective mineral exploration requires a detailed knowledge of the factors and processes which result in the formation of economic deposits. To apply this knowledge, a sound three-dimensional understanding of the geology and structure of a region is required. In most cases, surface geology can be mapped with a high degree of accuracy, however, the ge...
