Nature research paper: The importance of past rifting in large igneous province development

The importance of past rifting in large igneous province development - Nature
Seismic data from the Turkana Depression in East Africa show that areas of thinned lithosphere are not necessarily persistent weak zones where extension and magmatic provinces will develop.

Our new study is out in Scientific Reports!
@natureportfolio.nature.com. We use cluster analysis to reveal how the mantle source beneath the Afar Rift (Ethiopia) evolved during continental rifting.

Cluster analysis reveals increasing plume-like magmatism during progressive rifting in Afar (Ethiopia) - Scientific Reports
Reconstructing chemical variations of magma during rifting is challenging due to the heterogeneous mantle sources of the melt and different evolution pathways that magma potentially takes. Therefore, ...

Many oceanic islands far from active plate tectonic boundaries contain materials clearly originating from continents, even though they are located in the middle of an oceanic plate. Where do the continental remnants come from? @sasbrune.bsky.social, and lead author Thomas Gernon from 1/5
