摘要：

A synthesis is presented of the evidence for regional deglaciation, lake sediment stratigraphy, vegetation history and climatic variations in Quebec during that part of the Wisconsinan Late-glacial (1 2.5-9 ka BP) for which detailed records exist. Lake sediment data for all or part of this period are available from more than 125 lakes or bogs in the region. The information available indicates strong regional differentiation in climatic conditions, probably due to local effects close to the edge of the retreating Late Wisconsinan ice sheet. The Younger Dryas cooling is not evident in the data from Quebec, but there appears to have been a strong climatic reversal during the early Holocene. Summary charts are presented of deglaciation and vegetation patterns in the region, but only qualitative assessments can be made of temperature variations.
