Quaternary evaporite deposits

There are three depositional settings accumulating Quaternary-age evaporites: 1) Continental interior playas and salt lakes. 2) Seepage-fed marin-margin deposits. 3) Saline interior seaways. In terms of volume of evaporite salt accumulated, there are far greater volumes of salts in Quaternary continental salts than in marine-fed accumulations.

The table at the end of the localities listing illustrates climatic and physical properties for some of the Quaternary salt lakes discussed in this section. In the drainage basins of many of the continental lakes and especially those with the significant volumes of salt being preserved in the lake sump, there are outcrops or subcrops of salt diapirs sourced in older salt layers that underlie or lay adjacent to the present-day drainage sumps.
