Regional stream water geochemistry acquired as part of the Tellus programme in Ireland has been analysed to assess its potential for application environmental assessment and mineral exploration. Interpolated geochemical maps multivariate statistical analysis, including principal component analysis random forest classification, demonstrate broad geogenic control chemistry, with both bedrock subs...

taknar deposit is located about 28 km to the north-west of bardaskan in the khorasan-e-razavi province, which is situated in the north-eastern part of iran. this deposit is unique, formed within the taknar formation in the ordovician time. as a result, it is of much interest to many researchers working in this field. by choosing the lithogeochemical study performed to recognize new exploration ...

This report presents some strategies to predict metal mobility at mining sites. These strategies are based on chemical, physical, and geochemical information about metals and their interactions with the environment. An overview of conceptual models, metal sources, and relative mobility of metals under different geochemical conditions is presented, followed by a discussion of some important phys...

Lithium isotopes have many advantageous characteristics as geochemical tracers for a wide range of geological processes, covering fluid/melt-mineral interactions from the Earth’s surface to the mantle. The latest developments in Li isotope geochemistry, in terms of measuring techniques, major geochemical reservoirs, the contrasting behaviors during near-surface weathering, and crust/ mantle cyc...

The Bmnson Creek area (Figure 2-15-I) contains several significant mineral depnsits and showings, including Snip, the largest currently operating gold producer in British Columbia, owned by Cominco Metals (60%) and Prime Resources Group Inc. (40%). These occurences underscore the imponancr of understanding controls on mineralization as a guide to further exploration. For example, the Snip. John...
