Bedrock is the solid rock at or below the land surface. Over much of Ireland, the bedrock is covered by materials such as soil and gravel. The Bedrock map shows what the land surface of Ireland would be made up of if these materials were removed. As the bedrock is commonly covered, bedrock maps are an interpretation of the available data. <\/SPAN><\/SPAN><\/P>

Geologists map and record information on the composition and structure of rock outcrops (rock which can be seen on the land surface) and boreholes (a deep narrow round hole drilled in the ground). Areas are drawn on a map to show the distribution of rocks. <\/SPAN><\/SPAN><\/P>

Faults are vital information that is needed alongside bedrock geology maps to provide information on the structure of rocks.<\/SPAN><\/SPAN><\/P>

The faults show the details of the structural geology. Faults are the result of great pressure being applied to rock across a whole continent or more. These rocks will break under the pressure, forming faults. Faults are recorded as lines where the break in the rock meets the surface.<\/SPAN><\/SPAN><\/P>

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.<\/SPAN><\/SPAN><\/P>

Quaternary sediments are the soft material that has been deposited during this time. In Ireland much of this is related to the movement of glaciers and ice sheets. The main types of sediments shown on the map are tills (boulder clays), gravels, sands and peat. Over most parts of Ireland, these sediments cover the bedrock (solid rock at or below the land surface). <\/SPAN><\/SPAN><\/P>

Geologists map and record information from the shallow sediments which can be seen at or near the surface. This information along with boreholes (a deep narrow round hole drilled in the ground), geophysical data (information on the physical properties of the Earth's surface and subsurface e.g. magnetics, gravity and electromagnetics) and geochemical data (chemical properties) is used to create the map. Areas are drawn on a map to show where sediments are found. <\/SPAN><\/SPAN><\/P>

\u201cGeology\u201d within OneGeology-Europe is defined as \"composition (lithology/geochronology) and structure of the surface geology\u201d. <\/SPAN><\/SPAN><\/P>

Surface geology = geology that would be visible if the overlaying soil were removed, in other words: the Quaternary/superficial geology plus the exposed bedrock.<\/SPAN><\/SPAN><\/P>

Lithology refers to the rock type. Geochronology refers to the age of the rock.<\/SPAN><\/P>

To produce this dataset, the Geological Survey Ireland (GSI) bedrock geology 1:500,000 and 1:100,000 maps were generalised. Standardised EU field names and codelists were used and the GSI data was mapped to the specifications.<\/SPAN><\/P>

This map is to the scale 1:1,000,000. This means it should be viewed at that scale. When printed at that scale 1cm on the map relates to a distance of 10km.<\/SPAN><\/SPAN><\/P>

It is a vector dataset. Vector data portray the world using points, lines, and polygons (areas).<\/SPAN><\/SPAN><\/P>

The bedrock data is shown as polygons. Each polygon holds information on the GeologicUnit name, description, type, age, Observation Method, position accuracy, Event Environment, Event Process, Lithology, Younger and Older ages.

Rock properties and structures such as faults impact how water and/or pollutants move below the surface. Drinking water can be protected by locating potential polluting operations, such as landfills, away from groundwater.\n\nGeothermal energy is the energy stored in the form of heat beneath the surface of the earth. It can be used to supply heat and hot water. It can also be used to cool a house by removing surplus heat energy and putting it into the ground. Bedrock maps along with subsoil and aquifer maps are used to help decide if the ground under a site is suitable for geothermal energy extraction.\n\nEngineers need this information when they are designing structures (houses, buildings, roads, etc.). They need to know the quality of the ground (strength and depth of soil, if rock and or groundwater is present) and how structures can be built in and on it. They use the information to decide the best supports and foundations needed for structures so that they don\u2019t collapse. They can also find out if there are any underground obstructions, groundwater, faults etc which could result in additional costs or delays.\n\nBedrock maps are used to find sites suitable for the extraction of valuable mineral deposits.
