The inversion also produces outputs for the depth to the LAB, Moho as well as determine Vs and radiogenic heat production. These new results will be useful for future geodynamic modelling studies and understanding Ireland's tectonic history.

We've used phase velocity data combined with variable surface heat flow, thermal conductivity and radiogenic heat production to model the crust and upper mantle across the island.

New subsurface temperature models for Ireland have been published! In this work we used a joint geophysical petrological inversion to solve directly for temperature.

Excellent 2 days of fieldwork for the GRANNUS and MOD3LTHERM projects. 100% data recovery in Northern Ireland and we installed a fence to protect the equipment from cows. Thanks to Eoghan Totten @dias_geophysics
and Rob Raine @GeoSurveyNI for making this possible #Diasdiscovers.

The main controls on the temperature gradient were lithospheric and crustal thickness, however, thermal properties also significantly influence temperature with warmer geotherms found in granites and muds.

New surface-wave measurements across Ireland were used with thermal property, surface heat flow, Elevation and Moho depth data in the inversion procedure. We compared to direct temperature measurements in Ireland and found the model reproduced temperatures within error
