Complexities of geological processes portrayed as certain feature in a map (e.g., faults) are natural sources of uncertainties in decision-making for exploration of mineral deposits. Besides natural sources of uncertainties, knowledge-driven (e.g., fuzzy logic) mineral prospectivity mapping (MPM) is also plagued and incurs further uncertainty in subjective judgment of analyst when there is no r...

The area encompxses the headuatcrs of the Tulamecn. Snnss and Skaist rivers in the Ho~amccn Range\. 10 kilometres southeast of Hope and is hordcred by Manning Provincial Park on the southeast and Skagit Valley Recreation Arca on...

Geoscientists are increasingly challenged by the joint interpretation of ever-expanding amounts of new and historic, spatially-located exploration data (e.g., geochemistry, geophysics, geology, mineralogy, elevation data, etc.). And because, we can gather data faster than it can be interpreted, the availability of geographic information systems (GIS) has, to some extent, compounded, rather than...

Figure 1. Power spectra of two time series recorded at different times in the Sudbury area (Canada). Evident is the increase in the amplitude for the nighttime hours (bold lines) compared to the daytime hours (light lines). The continuous lines denote real part and the dashed linesimaginary parts of the spectra. Advances in aspects of the application of magnetotellurics for mineral exploration ...

Geochemical studies and surveys conducted by the Geological Survey of Canada have provided considerable information about the natural geochemical variations in glacial drift, lake sediments, and lake waters in south-central District of Keewatin. In addition to their intended contribution to mineral exploration, these activities yielded much basic background data that may be applied to the plann...

The Geological Survey Office (GSO) undertook a pilot study with the objective of assessing the ability of Survey data to support modern quantitative mineral potential modelling techniques. The Yarrol pilot project was designed to audit digital data sets routinely produced by the GSO, and to provide mineral assessment outputs relevant to both industry and Government decision-making processes. Th...

Remote sensing techniques and spatial data analysis through Geographic Information Systems (GIS) have been jointly applied in a mineral exploration context to identify gold-rich potential areas in SE Spain. Results conŽ rm the usefulness of this integrated methodological approach as an eVective tool to assess mineral potential in the studied region. Satellite and airborne image analysis have oV...
