Taking advantage of the extensive and detailed information
generated over the course of the Tellus Project: Summer 2019 sees a new field
mapping season to help update our understanding of the Quaternary geology over a study
area covering parts of Counties Roscommon and Kildare.
This survey will involve the use of:
Shallow geophysical surveys using Ground Penetrating Radar (GPR) and Electrical Resistivity Imaging (ERI) systems. GPR involves dragging the system on the ground to record subsurface discontinuities. ERI measures the subsoil conductivity from electrodes placed on the ground
Shallow drilling six inches diameter boreholes bored by a drilling rig mounted on a 4-wheel drive lorry. Boreholes are up to 20 m deep and are filled in after drilling.
Exposure recording consisting of description of shallow sediments exposed at surface and collection of samples to carry out further lab analyses.
N.B. The Quaternary mapping project is not a commercial
mineral exploration programme nor is it related to fracking, pylons or
