Thick layers of evaporites can accumulate as evaporation removes freshwater. Water evaporates and leaves behind dissolved minerals. Minerals are dissolved and carried into lakes and oceans by chemical weathering. Layers of chemical sedimentary rocks called evaporites form. The concentration of minerals reaches the saturation point. Crystal grains precipitate out of the solution and settle on the bottom.
