Abstract

A temperature catalogue containing all deep temperature information currently available for Ireland has been compiled using all classes of data. New equilibrium temperature measurements, thermal conductivity measurements, combined with those made by other workers, have been used to study geothermal gradients, subsurface temperatures, and heat flow density values in Ireland. Geothermal gradients show considerable variability but are generally below 15 degrees C/km in the south of the country, and often exceed 30 degrees C/km in the north. A localized region of high gradients in Co. Clare is due to Namurian sediments in the Clare-Shannon basin. Temperature maps at depths of 250m, 500m, 750m, 1000m, 1500m, and 7 km have been compiled. All the maps show a general northwards increase of subsurface temperature across Ireland, but the contours do not have the expected Caledonian trend. Thirteen equilibrium heat flow density values for Ireland are now available, a south to north increase is present.
