Primeros resultados de monitorización de la Cueva de El Recuenco (Ejulve, Teruel)
El Recuenco Cave (Ejulve, Teruel, NE Spain) is developed with a complex topography in Upper Cretaceous dolomitic limestones. A monitoring survey is in progress in the cave (covering now the 1st semester of 2013) in order to know the isotopic path from rainfall to dripwater and in-situ farmed calcite...

| Sumario: | El Recuenco Cave (Ejulve, Teruel, NE Spain) is developed with a complex topography in Upper Cretaceous dolomitic limestones. A monitoring survey is in progress in the cave (covering now the 1st semester of 2013) in order to know the isotopic path from rainfall to dripwater and in-situ farmed calcite. Rainfall results show that δ18O values reveal a clear seasonality (-12,73‰V-SMOW in winter, -8,94‰V-SMOW in spring). Dripwater values are mainly influenced by homogenization processes in the epikarst and also reveals seasonality in δ18O values (-10,9‰ V-SMOW in winter, -9,8‰ V-SMOW in spring). Finally, isotopic values of in-situ farmed calcite confirm this seasonality pattern (in δ18O values, -8,17‰ PDB in winter, -8,11‰ PDB in spring; also in δ13C values, -9,84‰ PDB in winter, -9,68‰ PDB in spring). Nonetheless, new monitoring tasks are needed to confirm this preliminary pattern. These conclusions will help to better interpret of speleothem records in this cave for paleoclimatic reconstructions |
