Sedimentological studies rarely reveal direct information about abrupt climatic changes. The interpretations of climatic changes, for instance at the end of the Pleistocene, are mainly based on fossils (in the Pleistocene deposits particularly on pollen) of species that are known to flourish within specific temperature ranges. The relatively scarce generally accessible literature data on the response of glaciofluvial and glaciolacustrine sedimentation to abrupt climatic change is based mainly on research of deposits formed at the Pleistocene/Holocene transition, which need, however, not necessarily reflect a representative climatic change (it may have been exceptionally fast). Such data, in combination with theoretical considerations, provide some insight in the tendencies that such sediments might show during climate changes. Yet, it is not well possible to determine during which timespan most of such climatic changes took place. More insight might be obtained by a structured analysis of well chosen sedimentological sections, in combination with detailed and accurate dating of such sections.
