Geothermometrical characterisation of low-temperature, carbonate-evaporitic geothermal systems is usually hampered by the lack of appropriate mineral equilibria to successfully use most of the classical geothermometers and/or by the thermodynamic uncertain ...

The Caldes de Boi geothermal waters show important differences in pH (6.5-9.6) and temperature (15.9 degrees C-52 degrees C) despite they have a common origin and a very simple circuit at depth (4km below the recharge area level). These differences are the ...

Peat layers within alluvial sediments are considered effective arsenic (As) sinks under reducing conditions due to the binding of As(III) to thiol groups in natural organic matter (NOM) and the formation of As-bearing sulfide phases. However, their possibl ...
