Sažetak
In the study, we present results of stable isotope analysis (δ18O and δ13C) of four U-Th dated stalagmites from the Eastern Adriatic caves. Two stalagmites (SPD-1 and SPD-2) were collected from Strašna peć Cave, situated on Dugi otok Island in the northern part, and other two from Mala špilja and Velika špilja caves situated on Mljet Island in the south¬ern part of the Croatian Adriatic. All caves formed in well-stratified Cretaceous limestones and stalagmites were deposited in isotopic equilibrium. The growth interval of the speleothems based on U-Th dating covers the period from 9.8 ka to 1.5 ka. In order to reconstruct the Holocene climatic conditions in the Eastern Adriatic, the speleothem isotopic record is discussed and compared with other Holocene records. Holocene in the eastern Adriatic is characterized by numerous isotopic fluctuations that reflect many and sudden changes in the environment. These changes coincide well with the other records, thus revealing regional events along the Eastern Adriatic. Despite these fluctuations, there is an expressed increase of isotopic values (δ18O and δ13C) from early to late Holocene, which primarily refers to the drier conditions in the Eastern Adriatic, which were occasionally interrupted by wet stages. Humid conditions are particularly pronounced between 7.3 and 6 ka, as a reflection of increased precipitation and low temperatures. The transition to today's Mediterranean climate (Cs) occurred between 6 ka and 5 ka. Periods of drought occurred around 4.7 at 4.3-4 ka and around 3.5 ka, with relatively wet phases between. From 3 ka, there is a general trend towards dryness. Moreover, there is distinct trend of drying during the Roman Warm Period and further toward the Dark Age Cold Period (DACP) with shorter periods of wetter conditions.
