This paper presents new and corrected data on the critical shear stresses required to initiate erosion as a function of type and amount of clay, pore and eroding fluid composition, and degree of dispersion as influenced by ion exchange. Data on the relationship between water uptake and critical shear stresses are also reported to support the fact that the mechanism causing erosion is due to the local swelling developed in clays.
