Summary: The PP10 stalagmite from Poleva Cave provides a Late Pleistocene and
Holocene isotopic record characteristic for the SW of Romania, a sub-
Mediterranean climatic region. The speleothem was dated by eight TIMS
and one alpha U-series dates which showed that it was precipitated
between ~75 ka and ~2 ka with at least two hiatuses. The basal sector
of the stalagmite showed a slow-growing regime of ~0.26 cm/ka, while
the upper one grew relatively fast with about 5 cm/ka. The temporal
resolution for the isotopic sampling is thus ~2 ka/sample for the
lower sector, and ~150 years/sample for the upper one.
The relationship between d18O and temperature was found positive.
The isotopic record of the lower sector shows two marked cold intervals
during ~67 and 58 ka and ~40¿35 ka, respectively, which correlate well
with the Villars and Soreq records. The upper sector record is so far
the most detailed Holocene isotopic record in Romania and the only one
available for the regions located at the exterior of the Carpathians
Range. The signal shows a gradual warming after the GS1 event
punctuated by several cold events at ~8, 7.2 and 4.2 ka and also by
warm oscillations centered at about 5.2 and 3.3 ka. The results seem
to indicate that if the North-Atlantic first order signals may extend
well to the south-eastern Europe, their amplitude and general trend
may be diminished by the interferences with the Mediterranean
circulation.
