The Voltaian Basin is a foreland basin formed by sediments filling a flexural depression at the margin of the West African Craton. The flexure is due to a northwest obduction on the craton of the younger Pan African crust.[2] The Basin covers about forty percent of Ghana's continental landmass and stretches across six countries, viz Benin, Burkina Faso, Cote d'Ivoire, Mali, Togo and Ghana, even though the Volta River flows primarily through Burkina Faso and Ghana.

The Republic of Mali is a landlocked country in West Africa, a region geologically identified with the West African Craton. Mali is the eighth-largest country in Africa, with an area of over 1.24 million square kilometers.
The interpretation of the AMT data and correlations with geological facts confirmed the author's proposition that the southwestern part of the study area is perfectly linked to the collision between the Pan-African Chain and the Congo Craton. Fractures have been highlighted from the image of the subsurface by combining the classical and the Bostick approaches in the interpretation of AMT data in the Akonolinga-Ayos region, westward from the current study area [12].
For the study, published in the journal Nature Communications, the researchers studied exceptionally well-preserved deposits which are approximately 3.5 billion years old in the ancient Dresser Formation in the Pilbara Craton of Western Australia.
