Anza trough
rift in Kenya that was formed in the Jurassic Period
The Anza trough is a rift in Kenya that was formed in the Jurassic Period of the Mesozoic Era.
The trough runs inland from the coast in the northwest direction.
The trough is an isolated graben originating from the uprising mantle-plume rift forming processes. It is not connected to the East Kenya Jurassic triple junction but temporally associated with the CARS formed during the initial stretching phase when Gondwana was breaking up.
The rift was formed by the same forces that created the rift system in South Sudan, and connects those rifts to the Lamu embayment further to the south.
The separation of the other two arms of the junction allowed India-Madagascar to separate from Africa.
The trough is now hidden by a cover of Quaternary sediments and volcanic rocks.
This brief starts where responsible research should: with the source description of “Anza trough” as rift in Kenya that was formed in the Jurassic Period. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as rift in Kenya that was formed in the Jurassic Period. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 28, 2025. The linked authority identifier is Q4778408. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
