Thermal conductivity measures the ability of an object to conduct heat. This happens when heat moves through the body of the object itself. Many things affect how the heat flows through the object. An important one is what material the object is made from. Copper, gold and iron are examples of good conductors but wood, rubber and glass are bad conductors of heat. The speed at which heat travels through the object is used to measure the thermal conductivity.
Rocks can conduct heat differently depending on the composition of the different types of rocks. Thermal conductivity maps can show how different rock types in an area conduct heat. It shows how well or how poorly the rocks will conduct heat. Sandstone and quartzite are rocks that are examples of good heat conductors. Shales and Basalts are poorer heat conductors. Geothermal 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 extra heat energy and putting it into the ground. It is a form of renewable energy. Geologists and engineers can extract this heat energy from below the surface and use it to heat homes and businesses. Thermal conductivity maps are important to geologists to help them design the best possible systems for geothermal energy extraction. They must know if the rocks below the surface have high thermal conductivity. This means that the rocks will be better conductors of heat energy.
Thermal conductivity maps are also useful for people who own homes and businesses. If they are interested in using geothermal energy to heat the building, they can use the map to see what type of conductors the rocks in their area are. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Thermal conductivity measures the ability of an object to conduct heat. The thermal conductivity map shows the measure of thermal conductivities for the different bedrock types in Ireland. Bedrock is the solid rock at or below the land surface. As there are many bedrock types in Ireland, it is not possible to take a measurement from all of them so the points on the map correspond to the thermal conductivity of the rocks in that specific area.</SPAN></SPAN></P><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Geologists record thermal properties of rocks. Thermal conductivity is recorded by measuring the speed at which heat travels through the rock type. This is recorded from a borehole (a deep narrow round hole drilled in the ground) or by measurements on pieces of rock taken out of the ground called drill core.</SPAN></SPAN></P><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>To create this dataset, existing data was collected from previous projects.
