Geochemical background is the basis of anomaly evaluation in mineral exploration and environmental investigation. However, value obtained from secondary media inevitably affected by weathering, transportation, sorting, which leads to depletion or enrichment chemical elements. This problem can be avoided geochemical mapping exposed crust. In this paper, more than 38,000 samples rocks data were c...

The basic differences between the application of till geochemistry in Finland and Canada are that (1) there is far less integration of glacial geology and geochemical exploration in North America than in Finland and (2) the application of new glacial sedimentology models and examination of basic assumptions about the history and dynamics of Scandinavian ice sheets are less emphasized in Scandin...

Exploration geochemistry continues to be a major contributor to mineral exploration programs at all scales. The decade has spanned a complete economic cycle in the minerals industry, during which there has been a change in exploration emphasis from the dominance of Au and diamonds to the addition of a range of base metals and the recent revival of U exploration. Increasing metal prices and the ...

In this thesis, the results from a geophysical mapping and coring campaign of Lagoa das Furnas are presented. Specific focus is placed on the origin of a subaqueous volcanic cone mapped in the southern part of the lake. Lagoa das Furnas is a crater lake within the Furnas volcanic centre which is located on the island of São Miguel in the Azores archipelago. The Furnas volcanic centre has a long...

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...
