ResumenThe spatial variability of vegetation and rainfall distribution across Spain is extreme compared to most other parts of the Mediterranean due to the Iberian topography and other geographic factors. This heterogeneity at the sub-regional scale has to be considered when interpreting the regional paleoclimate signal derived from the records. The NE regions of Spain are a clear example of such large climatic and environmental gradients in a N-S gradient from the Pyrenees to the Ebro River valley. Climatic and environmental reconstructions for the Central Ebro Basin are scarce, with poor chronologies, and consequently, regional reconstruction are heterogeneous and sometimes contradictory. More records and a multiproxy approach are needed to allow more detailed palaeoenvironmental reconstruction of Holocene climate in the area. To contribute to this purpose, we combined analysis of pollen, sedimentary facies and geochemistry, from two saline lake sequences located in Los Monegros region (Central Ebro Valley): La Playa and La Salineta.
