Calcium sulfate content of the Miocene alluvial-lacustrine Aktau succession in south-east Kazakhstan

The Aktau succession is located at 44.03°N and 79.30°E in the Ili Basin, south-east Kazakhstan. The dataset contains measurement results from the Middle to early Late Miocene part of the succession (total height: 372 m, lowermost sample: 0.29 m, uppermost sample: 370.94 m). CaSO₄ content were derived from bulk rock measurements. The CaSO₄ content was determined by microwave digestions and ICP-OES analysis.
