WebSep 18, 2015 · During mineral growth and dissolution, material (in the form of atoms, molecules, complexes, or clusters) is transported through water to or from the mineral surface. Even in a solution that is at equilibrium with respect to a given mineral, there is transport to and from the surface. WebOver time the dissolution can remove enough of the calcite to form caves. If dissolution of limestone or other materials removes enough rock to undermine support near the surface, the surface may collapse, creating a sinkhole such as the one in Figure 8.10, downstream of the Mosul Dam in Iraq.

WebThis concept means that if there is a change in physiographic configuration due to mineral extraction, it will impact the hydrological system. It should be noted that water resources are susceptible and often create and trigger conflicts of interest ( Gleick 1993; Kasymov 2011 ). WebWhen uplift and erosion brings bedrock to the surface, its temperature drops slowly, while its pressure drops immediately. The sudden pressure drop causes the rock to rapidly expand and crack; this is called pressure expansion. Sheeting or exfoliation is when the rock surface spalls off in layers.
