| Abstract | Cardoso, Hamza and Alfaro [4], identified more than 20 crustal blocks in South America with resources in the range of 1013 to 1014 Joules (between 1 to 10 Gwh) to the accessible depth limit of 3 km. High temperature resources are in the well known sector of magmatic activity in the Altiplano region in Bolivia, that may explain the high geothermal gradients in the Northern portion of Brazil. They also point to occurrence of medium temperature geothermal resources at depths of 3 to 5 km in some sectors of the eastern parts of the continent, mainly in the northeastern and central parts of Brazil. The West-central geothermal gradients are related to this central source. Their article also points to basal temperatures (of hard sediments) in excess of 300°C in the northeastern coastal region of Brazil and also along an east west trending belt between the northern part of the state of Mato Grosso and northern parts of the state of Rio de Janeiro in the central part and northwestern portion of |
