Isotopic Stratigraphy of a Last Interglacial Stalagmite from North-Western Romania: Correlation with the Deep-Sea Record and Northern-Latitude Speleothem
LFG-2, a 39.5 cm tall stalagmite from northwestern Romania, has been dated by U-series α -spectro- metric dating, and analyzed for stable isotope variations ( δ 18 O, δ 13 C) along its growth axis. The sam- ple grew all the way through oxygen isotope stage 5(a-e), and perhaps for some time into stag...
