Fig. 15From: Hydro-mechanical evolution of the EDZ as transport path for radionuclides and gas: insights from the Mont Terri rock laboratory (Switzerland)Characterisation of the EDZ in the HG-A microtunnel: 3-D laser scan with a tachymeter. Views are from the rear end of the tunnel towards the SSE side wall (top) and the NNW side wall (bottom), respectively. The radial accuracy of the scans is ±3 mm and the axial resolution varies between 5 and 10 cmBack to article page
