ScienceDirect The influence of hydrothermal activity on the Li isotopic signature of rivers draining volcanic areas
International audience We explore the geochemistry and the isotopic composition of lithium (δ 7 Li) of rivers draining volcanic islands (Guadeloupe, Iceland, Java, Martinique and Sao Miguel) with a specific focus on continental hydrothermal activity. Our preliminary results reveal a global-scale tre...
