英文摘要: Abstract(#br)Here, we report on Sr isotopes, from shallow and deep groundwater from catchments located on granite and schist around the world. This extensive approach of Sr isotope tracing, initiated in France on areas impacted by intensive agricultural activities, was enlarged to Africa (granite-gneiss and schists 2200-700 Ma of the Congo Basin; Archean granitoid/gneisses and sedimentary greenstone 3700-2500 Ma of the Orange River); India and Nepal (Archean granites 2500 Ma and Palaeoproterozoic granodiorite and schists 3100-1600 Ma for India; Himalaya metamorphic, silicate metasediments and gneisses 630 to 490 Ma); North America (3500–2500 Ma silicate rocks in the Mackenzie basin; 1000 to 70 Ma silicate rocks in the Fraser Basin in Canada and 1760 to 1430 Ma anorthosite and granite in...
