Evolution of Brestovská Cave Based on U-Series Dating of Speleothems
Evolution of Brestovská Cave Based on U-Series Dating of Speleothems The U-series dating indicates five episodes of flowstone growth in Brestovská Cave, namely: ca. 200 ka, ca. 128-88 ka, ca. 82-65 ka, ca. 64-50 ka, and during the Holocene. The age of flowstones and their spatial distribution within...
