Description
The host geology consists of layered sedimentary rocks overlying the crystalline basement at the northern edge of the Molasse Basin. The host rock itself, the Opalinus Clay, is a moderately over-consolidated claystone which forms a layer somewhat more than 100 m thick and dips to the south-east at about 5º. The siting area is located at the edge of the zone influenced by the Alps. Tectonically, it is subject to a slight compressive stress but is not significantly deformed. It also lies within one of the seismically quiet areas of Switzerland, with a small uplift and erosion rate and average heat flow.
