caption_attribution_description: English: The southern portion of Gondwana soon after its assembly. A rift appeared as indicated by the thick black line about 500 mya. This flooded to form the Agulhas Sea. This sea filled with sedimenst that were to become the Cape Supergroup, which subsequently were folded into the Cape Fold Belt
context_page_description: The Okavango Dyke Swarm is a giant dyke swarm of the Karoo Large Igneous Province in northeast Botswana, southern Africa. It consists of a group of Proterozoic and Jurassic dykes, trending east-southeast across Botswana, spanning a region nearly 2,000 kilometres long and 110 kilometres wide. The Jurassic dykes were formed approximately 179 million years ago, composed of mainly tholeiitic mafic rocks. The formation is related to the magmatism at the Karoo triple junction, induced by the plate tectonic break up of the Gondwana supercontinent in the early Jurassic.
