Nitrate transport in heterogeneous bedrock aquifers is influenced by mechanisms that operate at different spatial and temporal scales. To understand these...
The Zn-Pb carbonate-hosted deposit of Jubilee, Cape Breton, Nova Scotia, shows organic matter and clay mineral alteration assemblages that are attributed to...
In this study, tree-ring concentrations and stable isotope ratios of nitrogen in red spruce trees growing near Québec City (Canada) were used as records of...
Several carbonate-hosted lead-zinc deposits, displaying replacement and/or open-space-filling textures, occur in the Lower Windsor Group (Visean) of Nova...
Although the environmental impacts of metal atmospheric emissions from point sources such as smelter have been extensively studied, very few studies have...
Tree-ring nitrogen concentrations and isotope ratios (d15N) are gaining in popularity for environmental research although their use is still debated because of...
Is it possible to recognize source types of emissions using isotopic ratios in reactive-nitrogen (Nr)-bearing air species collected several kilometers downwind...
Diagenetic analysis based on cathodoluminescence petrography, cement stratigraphy, carbon and oxygen stable isotope geochemistry, and fluid inclusion...
Various interpretations have been proposed for the origin of peculiar cone-shaped, finely crystalline, Devonian carbonate mounds of the Hamar Lakhdad Ridge,...
The St. Lawrence Lowlands platform, Quebec, Canada, is a densely-populated area, heavily dependent on groundwater resources. In 1999, the Geological Survey of...
