Probing the southern African lithosphere with magnetotellurics: 2. Linking electrical conductivity, composition, and tectonomagmatic evolution
The tectonic history of southern Africa includes Archean craton formation, multiple episodes
of subduction and rifting and some of the world's most significant magmatic events. These …

Role of metasomatism in the development of the East African Rift at the northern Tanzanian divergence: Insights from 3D magnetotelluric modeling
Abstract The Northern Tanzanian Divergence in the East Africa Rift is arguably the best
place on Earth to study the controls on rifting of thick lithosphere. Here, where the East Africa …

Kimberlite segregation from an uppermost asthenospheric thermal boundary and the longevity of cold craton roots
Abstract Long-lived (> 2.5 Ga) cratons usually preserve ancient cold and refractory mantle
roots, but how the deep roots survive from recycling back to the convective mantle remains …
