Abstract

Springs from Analavory are geothermal waters which have undergone a complete cooling during their way towards the surface. Chemical analysis at emergence show that they are, at depth, anoxic, oversaturated with respect to CO2 and calcium carbonates. A considerable variation in the chemical composition of the springs is noted. Fluids from volcanic area of Itasy (magmatic-associated system) have higher Na, K and Cl concentrations and have lower Mg and Ca concentrations compared to their extensional counterparts. These differences are observed inspite of the fact pH and conductivity. Outgassing and oxygen input at the surface are the main parameters which allow to explain the observed composition. Appling silica and cation geothermometers lead to an estimation of about 154°C in the deep geothermal reservoir.
