Mesozoic alkaline volcanism and mantle evolution of the southwestern São Francisco craton, Brazil
… related alkali igneous rocks to variations in age, thickness and thermodynamic history of their continental lithospheric hosts. The São Francisco craton is a mid- to late-Archean basement granite-greenstone terrain flanked to the west by the Proterozoic Tocantins Province (Almeida, 1977, …

History of the fluids associated with the lode-gold deposits, and complex U-PGE-Au vein-type deposits, Goldfields Peninsula, Northern Saskatchewan, Canada
… metamorphosed sedimentary sequence, the Aphebian-aged Murmac Bay Group (complex Au-PGE-U vein-type deposits, e.g. Nicholson, Fish Hook), or within granites "intrusive" into the Group (lode-gold deposits, e.g. Box, Athona, Frontier). The complex Au-PGE-U vein-type deposits, and other minor …

Rb-Sr Alter und Sr-Pb Isotopencharakteristik von Gangmineralisationen in paläozoischen Gesteinen am Nordrand des linksrheinischen Schiefergebirges (Raum Stolberg-Aachen-Kelmis) und Vergleich mit den rezenten Thermalwässern von Aachen-Burtscheid
Vein mineralizations of different age and formation were studied in the northern Eifel area and its foreland. The focus was put on microstructure, geochemistry and isotopic composition to characterize discrete fluid flow events and to date their generations. Samples from the geothermal well RWTH – …
