Description: In terms of time scale in geology, Quaternary is the present-day time and it began 2.6 million years ago. A lot of this time period relates to the Ice Age. Quaternary geomorphology is the record of landscape features that were created in the last 2.6 million years. In Ireland, movement of glaciers and ice sheets created many of these features. An erratic is a rock which has been moved by ice and deposited in another location. Erratics are identified as the erractic rock type is different to the usual rocks found in that location.Geologists study the composition of erratics and can determine where the rock came from (the source). Once the source is known, the direction of ice flow can be determined (Inferred Erratic Path). The end of these erratic flow paths are termed erratic limits. We collect new data to update our map and also use data from other sources. Areas are drawn on a map to show where sources are found.This map shows the currently mapped Erratic Carriage Sources in Ireland.This map is to the scale 1:50,000. This means it should be viewed at that scale. When printed at that scale 1cm on the map relates to a distance of 500m.It is a vector dataset. Vector data portray the world using points, lines, and polygons (areas).The data is shown as polygons. Each polygon holds information on the glacial landform type, data source, rock unit name and its unique identifier.
