description Benue Trough Overview
The Benue Trough is a major geological rift basin in Nigeria that follows much of the Benue River valley. It formed during the Cretaceous as tectonic forces affected the African part of Gondwana during the opening of the South Atlantic and the separation of Africa from South America. The trough contains thick sedimentary sequences and is commonly divided into northern, central, and southern sectors. It is important to African geology because its rocks record Mesozoic and later basin development in West Africa.
help Benue Trough FAQ
Where is the Benue Trough located?
The Benue Trough is a major geological rift basin in Nigeria. It follows much of the Benue River valley.
When did the Benue Trough form?
The Benue Trough formed during the Cretaceous. Its development was linked to tectonic forces affecting Africa during the opening of the South Atlantic.
What does the Benue Trough have to do with South America?
Its formation is connected with the separation of Africa from South America as Gondwana broke apart. The opening of the South Atlantic created the broader tectonic setting for the basin.
Is the Benue Trough a river valley or a geological basin?
It is a geological rift basin that follows much of the Benue River valley. The river helps define its modern geographic expression, but the trough itself formed through tectonic processes.
