Salt tectonics, or halokinesis, or halotectonics, is concerned with the geometries and processes associated with the presence of significant thicknesses of evaporites containing rock salt within a stratigraphic sequence of rocks. This is due both to the low density of salt, which does not increase with burial, and its low strength.[1]
Salt structures (excluding undeformed layers of salt) have been found in more than 120 sedimentary basins around the world.[2]
