Radiocarbon and uranium-series dating of travertine

In this paper we present the results of radiocarbon and 230Th/234U dating of travertine samples from two karst areas in Croatia: the Plitvice Lakes and the Krka River. Both areas are situated in the Dinaric karts region and belong to the National Parks. Recent travertine was found along streams and lakes, and its precipitation is presently very intensive, whereas old travertine deposits were found as outcropping above the present water level. Radiocarbon and uranium-series dating of travertine showed good agreement (Holocene samples) and reproducibiliy of the resluts for hard, compact, crystalline calcite. Porous travertine samples are contaminated with recent carbonate, and thorium detritus or uranium leaching is possible. travertine samples from both investigated areas belong to Holocene and Riss/Wuerm interglacials.
