Grain size and clay mineralogy data of the Esplugafreda sequence (Spain) with stable carbon, oxygen and clumped isotope data of soil carbonates

This datasets contains 1) grain size distribution data of mudstone paleosols of the Esplugafreda sequence (Esplugafreda and Claret Formations) measured by laser diffraction, and 2) clay mineralogy measured by powder X-ray diffraction, as well as 3) stable carbon, oxygen and clumped (D47) isotope compositions of soil carbonates. The Esplugafreda sequence is found in the Tremp-Graus Basin in the southern forefront of the Pyrenees and consists of continental sediments formed in a coastal alluvial setting during the late Paleocene and early Eocene. In addition, a proxy dataset of late Paleocene and PETM continental temperatures of the northern hemisphere is also included.
