Gypsum grain size. Things To Know About Gypsum grain size.

This is because gypsum crystals are characterized by high-hydrophilicity. Under the effect of surface tension, water may easily infiltrate into the inner part of the specimens in the form of adsorbed film, creating a wedge cutting force (or expansion force). Hence, the gypsum grains are broken into discontinuous and small crystal cluster.Minerals of this size, where individual grains cannot be identified by the naked eye, are generally the weathering products of rocks found far inland away from the beaches.
