New Quaternary Mapping Project Commences
Taking advantage of the extensive and detailed information generated over the course of the Tellus Project: Summer 2016 will see new field mapping to help update our understanding of the Quaternary geology over a study area covering parts of Counties Cavan, Leitrim, Longford, Monaghan Roscommon and Westmeath.

GSI mapping area 2016

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 wind-farm development.
