Fig. 1.19. The fit of the continents bordering the Atlantic , as proposed by E. C: Bullard et al. (i n
Blackett et al. 1965). The fit is based o n matching the 500 fathom (900 m) contour. Note the Niger
Delta overlap. which is expected, and the Bahamas overlap, which is unexplained. Note also the
position of Gibraltar relative of Africa, and the "closure" of the Bay of Biscay. The ali gnment of the
Paleozoic fold belt s in North America and Europe and in South America and Africa (here added) is
remarkably good. a Caledon ian fold belt; h Hercy ni an fold belt; c Panafrican fold belt. [From
various sources, Panafrican belt after C. 1. Archanjo and 1. L. Bouchez, Bull. Soc. Geol. France,
