Abstract
The Fuentillejo maar is located in the Central Spanish Volcanic Field of Campo de Calatrava (Ciudad Real). Fuentillejo maar-lake is a closed system covering over 142 m depth of lacustrine sediments. Palynological, mineralogical and sedimentary facies analysis were performed to characterize the sedimentary record in the 167 to 120 ka interval of core FUENT-1 (67 to 48 m depth). These proxies allowed to reconstruct the paleoenvironmental and paleoclimatic processes which controlled vegetation patterns and deposition of sedimentary facies. Last Interglacial ranges between 133 ka and 120 ka in the Fuentillejo sequence. Lacustrine facies are made of finely laminated black-brown dolomicrite mud and sapropel layers. Vegetation is characterised by high pollen taxa diversity together with a high content in the Mediterranean and mesic forest components and a reduced content on Artemisia, Pinus and Juniperus taxa. A previous warm and humid phase at the end of MIS 6 (between 147 and 140 ka) was observed, indicating a higher biodiversity, an increase of Mediterranean forest and reduced catchment erosion.
