Reconstrucción paleoclimática del centro de la Península Ibérica durante los últimos 50 ka cal. BP, a partir de los datos físicos y geoquímicos del registro lacustre del mar de Fuentillejo (Campo de Calatrava, Ciudad Real)

Abstract

Physical (magnetic susceptibility and gamma density measurements) and geochemical (TOC, Fe and Ti analysis) analysis were performed to characterize the sedimentary record in Fuentillejo maar-lake (Campo de Calatrava Volcanic Field) in order to reconstruct the paleoenvironmental evolution, which controlled deposition of different sedimentary facies. The upper 20 m of FU-1 sequence point out variations in clastic input, water chemistry and organic fraction in the lake throughout the last 50 kyr cal. BP. Magnetic susceptibility are roughly influenced by diagenetic changes in organic rich sediments
