Mid-Holocene Climate Record in Santovka Travertine (Slovakia) and regional Biases of Climate Shifts 8.2 and 7.4 ka BP
The study of freshwater carbonates, such as travertines and speleothems, provides valuable insights into the regional biases of mid-Holocene climate development in Central-Eastern (CE) and South-Eastern (SE) Europe. The formation of a lake in the travertine deposition system of the Santovka site, lo...

The study of freshwater carbonates, such as travertines and speleothems, provides valuable insights into the regional biases of mid-Holocene climate development in Central-Eastern (CE) and South-Eastern (SE) Europe. The formation of a lake in the travertine deposition system of the Santovka site, located at the transition of the Western Carpathians and the Pannonian Basin, has led to the preservation of a valuable record. We analyzed the litho- and microstratigraphy, chemical composition, including δ 18 O and δ 13 C stable isotopes, and geochronology of the Santovka-village section. We then compared these palaeoclimatic records with reference records from Central-Eastern and South-Eastern Europe in terms of significant climate shifts.
