Gibraltar Arc Gibraltar Arc The Gibraltar Arc is a geological region corresponding to an arcuate orogen surrounding the Alboran Sea, between the Iberian Peninsula and Africa. It consists of the Betic Cordillera (south Spain), and the Rif (North Morocco). The Gibraltar Arc is located at the western end of the Mediterranean Alpine belt and formed during the Neogene due to convergence of the Eurasian and African plates. Maximum altitudes of the region are reached at the Mulhacén peak (3482 m) at the Cordillera Betica. Precipitation is collected mainly by the Guadalquivir (Betics) and Sebou (Rif) rivers, which have delivered most sedimentary infill
Black Country demonstrates Black Country crafts and industry from days gone by and includes many original buildings which have been transported and reconstructed at the site. The history of industry in the Black Country is connected directly to its underlying geology. Much of the region lies upon an exposed coalfield forming the southern part of the South Staffordshire Coalfield where mining has taken place since the Middle Ages. There are, in fact several coal seams, some of which were given names by the miners. The top, thin coal seam is known as "Broach Coal". Beneath this lies successively the "Thick Coal", "Heathen
