Resumen
Lacustrine and travertine records from Laguna de Taravilla (Iberian Range, Guadalajara province,Spain, 40s 39' N, I s 59' W, 1100 m a.si.) have been analysed using sedimentological, mineralógica!, geochemical and palynological techniques. A preliminary chronological framework is basedon U/Th, 14C AMS, 2WPb and 137Cs dates. Phases of increased travertine growth occurred duringthe Glacial- Interglacial transitions from isotope stage 6 to 5 and 2 to 1. Short lacustrine cores indicate a lake level increase after the XVth century; that can be correlated with the end of the Medieval Warm Period. Sandy facies related to flood events are more frequent during the intervalascribed to the Little Ice Age. During the last century, the growth of littoral vegetation at the mouthof the inlet could have prevented more sandy sediments to reach the center of the lake
