- •
A novel method is proposed to test for secondary exchange of gypsum hydration water.
- •
We studied one cycle of gypsum–marl deposition from the Messinian Yesares Member.
- •
We show that gypsum hydration water has retained its original isotopic composition.
- •
All isotope signatures can be reconciled if marine sulfate minerals are recycled.
- •
Results support cyclic evaporite deposition forced by Earth's orbital geometry.
