Late Pleistocene - Holocene changes of the eastern Adriatic coast line

Eastern Adriatic Coast is a typical ingressional coast formed during the last, Late Pleistocene - Holocene sea level rise by the flooding of existing karstified area. The most remarkable evi-dence of that event is submerged karst relief including caves and pits with the speleothems in-side them. This work is based on the radiocarbon dating of submerged speleothems, which are typical subaerial features. Their finding under the present sea level indicates that in the recent geological history the sea level was at the lower position. Before approx. 10, 5 and 9 ky, it was between 36 and 34 m below recent sea level, whereas cca 8 ky it was 23 m below. The age of the youngest layer of the speleothem indicates the immediate time before the speleothem growth ceased, either by freshwater or sea water flooding, whereas the age of marine biogenic deposits that cover the speleothems expresses the earliest time when the marine organisms started to grow over the speleothems in caves flooded by the sea water.
