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. Deglacial landforms are created at the ice margin. They were created during ice retreat. A moraine is material left behind by a moving glacier. This material is usually loose sediment and rock debris (glacial till). Kame terraces, deltas and fans are all ice marginal landforms deposited by water issuing from a glacier.Geologists map and record evidence from the shallow sediments visible at or near the surface, from air photographs and from Digital Elevation Models (DEMs). This data along with boreholes (a deep narrow round hole drilled in the ground) and geophysics help to create the map. Areas are drawn on a map to show where features are found.We collect new data to update our map and also use data from other sources.This map shows the currently mapped Deglacial landforms 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, name, data source, data reference and its unique identifier.
