abstract = {Se/enaíe (SeOf) and sulfate (50/-) have similar structural and chemical properties, and they can play a similar geochemical role. The competition between both anions has been considered in different fields.

We present experimental work on crystallisation of Ca(Se04,SC)J-2H20 solid solutions from aqueous solutions. A complete structural characterization of solid solutions by X-ray powder diffraction and thermocalorimetic analysis were carried out. The differences in structural parameters for the different solid compositions have allowed us to quantify the non-ideality of the solid solution and the calculation of a thermodynamic model of this solid solution-aqueous solution system.

In addition, the work includes some observations on dehydration behaviour of CaSe0/2H20- CaS042H20 endmembers and solid solutions},
