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 Quaternary continental salts than marine-fed accumulations.

The table below illustrates the climatic anf other properties of some of the Quaternary salt lakes discussed in this section. In many of the lakes and especially those with the significant volumes of salt being preserved in the lake sump, there are outcropping or subcropping salt diapirs in their dranage basins.
