This model covers an aerial extent of 135x115m and shows, in the foreground, a towering, N10°-striking, 4-m-thick basaltic vertical dyke, made prominent by the erosion of the surrounding country rocks, in which it had originally been intruded. See country house for scale. In the background, a cliff can be noticed, made of a succession of basaltic lavas dipping at a shallow angle to the west (left). Some inclined sheets (e.g. Tibaldi et al., 2013), dipping at steeper angle, cut the lava succession. A couple of vertical dykes, with slightly different strikes, cross-cut the lava succession as well. The area is located in eastern Iceland, within Tertiary age units; further details on the dykes and geology in eastern Iceland can be found in Walker (1974), Gudmundsson (1983), Jóhannesson and Sæmundsson (1998) and Gudmundsson et al (2014).
