This is a very ambitious work. The authors discuss the geology of Britain as a “geological legacy”, that is, they believe it is “an inheritance bequeathed to 11 millennia or so of its post-glacial inhabitants”.
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. In fact, the book goes into some detail, using colour photographs and block geomodels, to bring the subject to life in what is, I suspect, a somewhat fresh way.
Nouvelle-Aquitaine (New Aquitaine) is a vast region of southwest France covering more than 30,000 square miles. Between 1154 and the end of the Hundred Years War in 1453, much of the region was under British control. Links with Britain are still strong today, both through tourism and the large ex-patriate British population, particularly in the Dordogne, known jokingly to locals as ‘Dordogneshire’.
About 61 years ago, a boy wandered among loblolly pines near an agricultural field not far from the Nottoway River in southern Virginia in the USA. 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).
