Synopsis

The principal types of stratification and some characteristic sedimentary sequences found in vegetated coastal dunes in Atlantic Canada are described. Four examples are selected to show a range of dune types and depositional settings. In each case the documentation and interpretation of the internal structure and stratification has made an important contribution to understanding the evolution of the dunes. Stratification and depositional models are presented for:

(1) a single, continuous, transgressive foredune ridge which maintains its form during transgression;

(2) a discontinuous transgressive foredune ridge, interrupted by washover passages;

(3) a “precipitation” dune, which buries an existing stable dune; and

(4) complex dunes produced by two or more phases of aeolian activity characterised by different plant associations.
