Table 6 Features summary of the potential geothermal system located in the Tete area
Main Geothermal Reservoir | Geological Formation | Thickness (m) | Permeability | Estimated temperature (°C) | Type of geothermal system | Chemical features of the fluid | Potential use of the resource |
|---|---|---|---|---|---|---|---|
Precambrian Basement | Tete Suite | 1500 ÷ 2000 | Secondary permeability related to fractured–faulted rocks and dikes | 90 ÷ 100 | Igneous, basement-type geothermal play sensu Moeck (2014) or unconventional Geothermal System (e.g., Enhanced Geothermal System—EGS) | - Na–Cl - low TDS - no corrosive gas phases | Direct Use: livestock farming, agriculture, pasteurization, beet sugar extraction, distilled liquor, lumber, ecc |
Crystalline basement | > 2000 | 110 ÷ 120 | Indirect Use: power generation by binary cycle and/or conventional flash plants |
