Variation of salt or silica solubility as a function of water activity, capillarity pressure or pore size, is discussed as a probable origine of matter migration, concentration, and finally concretioning.La variation de la solubilité des sels et de la silice en fonction de l'activité de l'eau, de la pression capillaire ou de la taille des pores est considérée comme une cause probable de migration ou de concentration de matière. Le mécanisme du concrétionnement est discuté.Tardy Yves, Monnin Christophe. Recherches sur les mécanismes du concrétionnement.
