Abstract
A description of the stratification within the dunes of Sable Island, Nova Scotia provides the basis for an interpretation of the processes operating throughout their history. Particular importance is attached to the role of vegetation in deposition history. Each plant community found in the dunes, has an associated set of structures which are the signature of deposition within, and in the lee of that group of plants. The Sparse Marram Community can be recognized by packets of sand laid down by tractional and grainfall deposition. The Dense Marram Community is associated with predominantly grainfall deposition which results in horizontal, parallel and wavy laminated beds of loosely compacted, finer sand. The Shrub Heath Community is represented by horizontal, continuously laminated beds with organic staining and woody root fragments, is often associated with a paleosol.
