Abstract
Lithostratigraphical interpretation and 14C dating of adjacent lake-side sedimentary sequences at the Sulivan House lakes, West Falkland, indicate between-site non-synchronous records of Holocene aeolian sand deposition and landscape stability. It is inferred that the sands are associated with deflation of exposed sandy shorelines at times of lower lake levels, whereas stability phases are characterised by peat formation and/or organic matter incorporation into sand horizons at times of ‘normal’ lake levels. The data imply that a cautious approach to interpretation of lake-side sediments may be warranted if the purpose is to use lake-level changes and aeolian — non-aeolian interbeds as proxy indicators of regional climatic signals. © 1998 John Wiley & Sons, Ltd.
