Fig. 2From: The influence of hydrothermal brine on the short-term strength and elastic modulus of sandstones from exploration well EPS-1 at Soultz-sous-Forêts (France)Photographs of the six sandstones (20 mm-diameter core samples nominally 40 mm in length) sampled from exploration well EPS-1 at Soultz-sous-Forêts (France). The box number, lithological unit, and depth are given above each sample. A stratigraphic column showing the units within the Buntsandstein from exploration well EPS-1 at Soultz-sous-Forêts (Alsace, France) is shown on the left hand side. The locations for each of the sampled depths are indicated on the stratigraphic columnBack to article page
