Potentially important uncertainties remain regarding the variables which control weathering fluxes in these regions, which are often hydrothermally-active.&nbsp; In turn, these uncertainties prevent accurate estimates of atmospheric CO<sub>2<\/sub> consumption and production of solutes to the ocean. The objective of the research is to develop a detailed understanding of the factors influencing weathering fluxes from hydrothermally-active island arc and continental hotspot regions.&nbsp; The meteoric and hydrothermal sources and processes contributing to weathering fluxes are unraveled by an analytical approach combining the stable silicon isotopes and the germanium to silicon ratio.&nbsp; Three hydrothermal systems from volcanic island arcs are used as case studies: La Soufri\u00e8re volcano in Guadeloupe, Aso volcano in Japan, and Kawah Ijen volcano in Indonesia.<\/p>\n<p>Work led by Fran\u00e7ois Gaspard, PhD student, cosupervised by S.
