A borehole is any hole drilled or dug into the ground. The material (soil and or rock) from the hole is collected and tested in a laboratory to find out the structure and type of the soil and or rock beneath the ground. A borehole record or log is a written description of the...

The term Physiography can be described as a blending of “physical" and "geography". Physiographic Units show Ireland’s physical landscape divided into categories such as ‘Bedrock plain’ and ‘Flat to undulating sediments’. Areas are grouped based on bedrock geology (solid rock...

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 sediments are the soft material that has been deposited during this time. In Ireland much of this is related...

Minerals are naturally occurring; they are not made by humans. They are inorganic in that they have never been alive and are not made up from plants or animals. They are solid, not liquids (like water), or gases (like the air around you). Each one is made of a particular mix...

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...

These maps shows the aggregate potential across Ireland. To produce these maps, scores were given to each area based on several factors such as rock type suitability, number of quarries, area, elevation etc. The final score was a number between 5 and 100 The maps shows the...

The Quarry Directory shows the location of sand and gravel, crushed rock and dimension stone quarries in Ireland. A questionnaire was sent to all known active quarries and pits (around 1,700). A location map (Ordnance Survey Ireland (OSI) 1:50,000 Discovery Series) was...

The Dublin Soil Urban Geochemistry Project is a baseline survey of heavy metals and organic chemicals in topsoils in the greater Dublin area. Topsoil is the upper surface layer of the soil and this geochemical baseline survey measures the amount and type of chemicals in these...

This map shows the areas where sub-bottom profile data is available in Irish waters. Sub-bottom profile data shows the rock features and the sediment layers that are below the seabed. A sub-bottom profile is created by sending sound waves from the vessel to the seabed. The...

Sub-bottom profile data shows the rock features and the sediment layers that are below the seabed. A sub-bottom profile is created by sending sound waves from the vessel to the seabed. The length of time it takes for these sound wave to return from the seabed to the vessel is...

The INtegrated Mapping FOr the Sustainable Development of Ireland's MArine Resource (INFOMAR) programme is a joint venture between the Geological Survey of Ireland (GSI) and the Marine Institute (MI). The programme is the successor to the Irish National Seabed Survey (INSS)...

Geochemistry of streams sediments can be used to screen for rare minerals and thus help developing local resources. Knowing composition of stream sediments helps to understand what rocks were eroded by the water, where they came from and what resources they might contain....

This data shows the depth of the seabed around Ireland. The data was collected in 1996 and between 2000 and 2022. Bathymetry is the measurement of how deep is the sea. Bathymetry is the study of the shape and features of the seabed. The name comes from Greek words meaning...

Research ships working at sea map the seafloor. The ships collect bathymetry data. Bathymetry is the measurement of how deep the sea is. Bathymetry is the study of the shape and features of the seabed. The name comes from Greek words meaning "deep" and “measure". Backscatter...

Streams are important parts of our ecosystem and crucial water sources. Knowing composition of stream waters helps to understand where it came from and how it can be used. Geochemists test stream water samples using different methods to see the spread of elements and ions...

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. Geologists map and record information on the composition and structure of rock outcrops (rock which can be seen on the land surface). It...

EnvironmentSoil is the outside layer of Earth. It is a made up of living organisms, gases, minerals, and organic matter. Knowing what elements are in the soil helps to work out where it came from and how it was made. Deeper soil samples for the northern half of Ireland were collected by...

The Scheme Reports Groundwater Protection map provides links to county based reports. A groundwater protection scheme has land surface zone map(s) and groundwater protection responses for potentially polluting activities e.g., landfill, land spreading and septic tanks. The...
