A variety of regional geoscience datasets from Nova Scotia have been co-registered and analyzed using a geographic information system (GIS). The datasets include bedrock and surficial geological maps, airborne geophysical survey data, geochemistry of lake-sediment samples, and mineral occurrence data. A number of line features, including structural lineaments, fold axes and formation contacts, ...

The method of weights of evidence is one of the most important data driven methods for mineral potential mapping in GIS. In this method, considering the characteristics of known mineralized locations, we can prospect new mineralized areas. In this research work, the method of weights of evidence has been used for hydrothermal gold potential mapping in Torbat-e-Heydarieh area, east of Iran. As a...

Rock physics models allow establishing a physical-mathematical relation between rock and fluid properties and geophysical attributes. In this study, we propose to apply rock physics models to a geophysical dataset measured at two well locations near the proposed Snake River Plain FORGE site in eastern Idaho. The potential target is a rhyolite layer, which occurs between 2,000 and 3,000 m. The a...

The history of geophysics in Australia began with the first European explorers, who were concerned with the measurement of basic geophysical quantities, such as the Earth’s gravitational and magnetic fields (Day, 1966). By the first half of the twentieth century, Australia had been recognised as a possible happy-hunting ground for the new methods of exploration geophysics, as witness the accoun...

As the potential locations of undiscovered ore deposits become deeper, a technique for predicting promising areas in subsurface media has necessary. Geoscience data on wide range underground can be obtained through geophysical field exploration, but integration and interpretation multi-geophysical are difficult because differences spatial resolution. We developed rock classifier that predict va...

THE recent organization by the American Geophys-ical Union of two cooperative committees of national scope, the Special Committee on the Geophysical and Geological Study of Ocean Basins, under the chair-manship of Professor R. M. Field, and the Special Committee on the Geophysical and Geological Study of Continents, under Professor W. T. Thom, points unmistakably to a growing realization of the...

An object-oriented and map-based prototype expert system has been developed for integrating geophysical, geological data for base metal exploration. The object-oriented knowledge representation structure and uncertainty propagation mechanisms used work well for this integrated resource exploration problem. Evidential belief function theory is utilized to manage the uncertainties in the system. ...
