What is an evaporite deposit?
Quick Answer
An evaporite deposit is a layer of minerals left behind when salty water evaporates, concentrating salts until they crystallize.
The Full Story
Evaporites commonly form in restricted basins, shallow seas, or inland lakes where evaporation exceeds water input. As water disappears, minerals precipitate in a sequence that can include calcite, gypsum, anhydrite, halite, and potash salts. These deposits can be several kilometers thick in some ancient basins and are major economic sources of salt and fertilizer minerals. Evaporites also provide clues about past arid climates and changing sea levels.
Key Facts
1.Common minerals include gypsum and halite
2.They form where evaporation is high
