Lithium isotopes have many advantageous characteristics as geochemical tracers for a wide range of geological processes, covering fluid/melt-mineral interactions from the Earth’s surface to the mantle. The latest developments in Li isotope geochemistry, in terms of measuring techniques, major geochemical reservoirs, the contrasting behaviors during near-surface weathering, and crust/ mantle cyc...

Injection of CO2 in geological reservoirs or deep aquifers is nowadays studied to regulate the global warming by limiting the amount of greenhouse gases emitted by human activity into the atmosphere. CO2 is captured from exhaust gas in power plants or industrial units and then stored in underground geological reservoirs. The experience available in the oil industry concerning CO2 injection clea...

Introduction: Rio Tinto area is considered a referent as an extremophilic scenery of iron rich and acidic water conditions for life [1]. Physic-chemical equilibriums taking place along of its watercourse during a year produce a repertory of mineral species related with the main chemical species in solution (sulphates and iron). Raman spectroscopy is a powerful technique that allows studying the...
