Today’s post (21) Liberia has intrusive rock features with potential heat pathways able to be used to access geothermal heat resources but more exploration would be needed to see if reasonable well designs are possible. Part of the West Africa Craton, the Man Shield comprising two areas of Archaean and […]

Gabon is a country with good access to electricity for its population and is blessed with hydrocarbon resources which are exported. Electricity is about one half from carbon based fuels and one half from hydropower. Hydropower is a good renewable energy source, but it can have seasonal intermittency due to […]
Working offshore EG 20 years ago, it was impossible to miss Bioko’s Pico Basile Volcano rising 3000m above the island. And to the northeast on the African mainland, the Mount Cameroon Volcano rises over 4000m – very clear visual evidence of the Cameroon Volcanic Line (CVL) and the geothermal energy […]
Today’s post (18) is Egypt. The presence of the Red Sea failed rift and pulses of volcanism have led to significant heat flows and thermal springs along either side of the Gulf of Suez. Some of these springs have been shown to originate from high crustal heat flow and fault […]
Today’s post (17) Democratic Republic of Congo (DRC) is a country rich in mineral resources, but challenged to have enough energy to capture more value by processing these minerals prior to export. The population has almost no access to electrification and Energy Poverty makes it difficult to achieve any Sustainable […]
A number of countries in African have significant amounts of intrusive rock formations and associated hydrothermal mineralisation ore deposits. (16) Côte d’Ivoire is one such example. The use of Geothermal Energy for electricity would help reduce Energy Poverty, reduce carbon emissions, improve grid stability, and allow more domestic processing of […]
The Republic of Congo on the equator is covered 60% by forests and the rest by savannah. A population of ~5.6 million has an urgent need for improved living conditions, clean water and better sanitation, education, and economic growth. But these SDG’s need increased electrification to help address Energy Poverty. […]
Niger is covered ~80% by the Sahara Desert. Some outcrops of faulted gneissic formations are present. In central Niger, the Aïr Massif is a granitic extension of the Tuareg Shield of the Pan-African Belt. This Massif has different types of granitic plutons intrusions, resulting from pulsed magma in dykes rising […]
The geology of the central African country of Chad is dominated by the low-lying Chad Basin, which rises gradually to mountains and plateaus of the Tibesti Mountains in the North and the Ennedi and Ouaddi plateaus in the East. The northern half of Chad lies within the Sahara; The Chad […]
Botswana is fringed on the east by the Zimbabwe Craton and the south by the Kaapvaal Craton with Limpopo Orogenic Belt in between. In the southwest is the Kalahari Suture Zone (KSZ) which is a large scale (~400km x <50km) intrusive feature linked to the Kheis Orogenic Belt that extends […]
Angola has several geotectonic units including: (1) Congo Craton; (2) Orogenic Mobile Belts (including the Pan-African West Congolian) ; (3) interior sedimentary basins; and (4) perioceanic basins; An interesting geologic feature is the Lucapa Corridor extending from SW to NE Angola which has been attributed to mantle upwelling, lithospheric uplift, […]
In a series of informational posts about the Geothermal Energy Potential in Africa, we have up to now posted about: (1) Africa as a whole; (2) Cameroon; (3) Ghana; (4) Kenya; (5) Namibia; (6) Nigeria; (7) South Africa ; (8) Zimbabwe; and (9) the East African Rift System (EARS). Now we […]
