Book review: Geomodels in Engineering Geology: An Introduction, by Peter Fookes, Geoff Pettifer and Tony Waltham

As this book explains, ground conditions for building depend on the history of all these aspects in connection with both the actual building site and the surrounding area.

Geoarchitecture of some Romanesque churches in Aquitaine, France

Between 1154 and the end of the Hundred Years War in 1453, much of the region was under British control.

His eyes fell upon a tan coloured rock atop a thick layer of old needles at the bases of the pines. It was a curiosity – the coastal plain Southampton County does not feature rocks reposing at the surface. Young Lloyd Bryant turned over the rounded chunk of stone and was jolted to see an etched human face staring back (Fig. 1).

Very down-to-earth Vasquez rocks portray the surface of alien planets for the media

Deborah Painter (USA) They have become associated with stark alien or other-dimensional landscapes since the 1960s, when the popular American television programme Star Trek used them as dramatic backdrops in two episodes, “Arena” and “Friday’s Child”.
