The sediments from the Coari lake, a "terra firme" lake sculpted into Plio-Pleistocene deposits, and the Acará lake, a flooding-type lake developed on Quaternary sediments in the floodplain of the mid-Solimões river, in the western Amazônia, Brazil, were studied to investigate the environmental condition of their developing. This study includes mineral composition, geochemistry, Pb isotope, pal...

The characterization of metal release and attenuation in mining waste rock drainage has traditionally relied upon an array of mineralogical and geochemical techniques. Recent advances in analytical instrumentation now allow robust measurements of minute variations in the isotopic composition of metals in environmental samples, which have become a powerful new tracer of their fate. Here we provi...

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...
