... Urgeiriça mine is located in the central part of mainland Portugal ( Fig. 1 ), close to the city of Nelas. The region comprises granites and other rocks and is part of the so-called ‘Beiras Uraniferous Region’ which involves an area of c. 10 000 km 2 in the Central Iberian Zone. This flattened region...
