The Turkana Rift Zone is undergoing “necking,” a critical transition toward continental breakup that has never been observed before, researchers reported. www.sciencenews.org/article/africa-…

The crust under Africa is thinning in a way that hasn't been seen before
Africa’s Turkana Rift Zone, a hotbed of hominin fossils, is caught in the act of “necking," a critical transition toward continental breakup.

Breaking up is hard to do (for continents or anyone else), but a rift zone in Kenya may be closer to its breaking point than we thought. 🧪 eos.org/articles/eas...

The Turkana Rift Zone in Kenya entered a critical stage in continental breakup about 4 million years ago.

A study in Nature Communications indicates that the East African Rift System in northern Kenya may be closer to breaking apart than previously thought and that its development played an important role in the preservation of the hominin fossil record. go.nature.com/4vZvaec ⚒️🧪
This is figure 1, which shows global active and failed intracontinental rifts and the tectonic setting of the study.

Study by LDEO researchers/colleagues finds that Earth’s underlying crust in Turkana Rift region has been significantly thinned, presaging Africa’s eventual breakup—and with that finding, new perspective on how Turkana’s world-famous fossil record of human evolution came to be: bit.ly/41QD4ZC

Excited to share our new paper published today in @natcomms.nature.com! We find that the crust beneath the Turkana Rift is extremely thin, and that the rift’s maturation played a key role in shaping the accumulation of Turkana’s world-famous hominin fossil record. www.nature.com/articles/s41...
