DOI: 10.1007/s00603-018-1696-6
Abstract: Groundwater reestablishment in abandoned gypsum mines causes pillar dissolution until the groundwater reaches the groundwater’s gypsum saturation potential. In some cases, however, especially in shallow mines, groundwater can continue to flow through the mine resulting… read more here.

DOI: 10.1016/j.chemgeo.2020.119578
Abstract: Abstract Solution flow profiles near a mineral surface can exert significant influences on the local thermodynamic driving force and, potentially, the rate-controlling kinetic mechanism of its dissolution or precipitation. These influences are investigated here both… read more here.
