• Resumen

  • First stable isotope results from Molinos Cave (Teruel, NE Spain) highlight the importance of comparing speleothems from the same cave to extract climate information and discard other influences. From the integration of four stalagmites covering since the Holocene onset to 2000 cal yrs BP, the Early Holocene (11.7-8.5 ka BP) with δ13C values between -11 and – 9‰ appears as the wetter interval. The range of δ18O values is low (about 2‰) but still lighter values during Early Holocene and heavier afterwards are well marked. Shorter events characterized by more negative δ13C values are observed at 7.4, 8.2 and 9.2 ka and interpreted as cold but probably wetter periods with denser vegetation cover and soil development over the cave.
