| Abstract | This Open File contains a compilation of 122 published and unpublished radiocarbon dates relating to the age of 39 sensitive clay landslides and three "disturbed terrain" features in the Ottawa Valley,
southeastern Ontario/southwestern Québec. Sixteen tables contain either the date(s) for individual landslides (or disturbed terrain) or the date(s) for multiple landslides within a specific geographical area. A brief paragraph introduces each table
and overviews the landslide or disturbed terrain and the associated radiocarbon date(s). Each table lists the attributes of the dates, including sampling location, dated material, dating results, and contextual information between the age and the
landslide/disturbed terrain. It is intended that this dataset will aid future studies investigating the chronology of prehistoric sensitive clay landslides in the Ottawa Valley and St. Lawrence Lowlands region. |
| Summary | (Plain Language Summary, not published)
Large areas of the Ottawa Valley are underlain by clay and silt deposits that aggraded in the Champlain Sea at the end of the last glaciation. Some of
these deposits have experienced large landslides, known as earth flows or earth spreads. Over 250 landslide scars have been mapped in the Ottawa Valley. This report compiles 122 radiocarbon dates relating to the age of 42 landslides in the Ottawa
Valley. The landslide ages range from 'modern' to about 8000 year old. The dates are organized into 16 tables that list sampling location, dated material, dating results, and contextual information between the age and the landslide/disturbed
terrain. This dataset will aid investigations of the chronology of prehistoric landslides in the Ottawa Valley. |
