Landscape sensitivity to short and long term climate change during the Late Quaternary: Southern Spain

摘要: The Mediterranean region is one of key significance within palaeoclimatology and geomorphology. highly sensitive to both past future climatic changes, situated as it between arid North Africa temperate Europe. Proximity the Atlantic means also exposed changes in oceanic circulation that occurred over last glacial, thought be responsible for major shifts. impact glacial/interglacial stadial/interstadial climate shifts have been identified long pollen records Eastern (Allen et al. 1999, Tzedakis 2005) marine sequences (Cacho Sanchez-Goni 2000, Moreno 2005), however, our understanding these terrestrial settings relatively poor. Southern Spain represents a location further landscape response short-term because; 1) lies proximal position therefore, forcing, 2) contains sediment which record surface processes. Furthermore, due development techniques such OSL U-series now possible build robust chronologies extending range radiocarbon dating. This study will present work from loess palaeosol sequence Nerja Spain. section located deeply incised coastal valley composed interbedded loess/loessic, pedogenic, tufaceous fluvial sediments. presented appears depositional process during penultimate glacial (MIS6), interglacial (MIS5) deterioration leading into cold stage (MIS4).
