Abstract:

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). Stable carbon and oxygen istopes and CaSO₄ content were derived from bulk rock measurements. The CaSO₄ content was determined by microwave digestions and ICP-OES analysis. The laser ablation U-Pb data was aquired from thin sections in order to obtain radiometric ages of carbonates along the Aktau succession.
