The Transition to Tectonic Control of Magmatism in the East African Rift System—The 20 Ma Samburu Event Open
The Samburu Series magmas of the East African Rift System are a key component of the Early Miocene magmatic resurgence, marking the initiation of plate‐scale volcanic events associated with extension, distinct from the prior continental fl…

Basaltic Pulses and Lithospheric Thinning—Plio‐Pleistocene Magmatism and Rifting in the Turkana Depression (East African Rift System) Open
The East African Rift System (EARS) provides an opportunity to constrain the relationship between magmatism and plate thinning. During continental rifting, magmatism is often considered a derivative of strain accommodation—as the continent…

Messengers from the Magma Chambers: Petrostratigraphic Analysis of Plagioclase-Rich Flood Basalt Lavas in Turkana, Kenya Open
Continental large igneous provinces are among the largest magmatic events on Earth, characteristically manifesting at the surface as stacks of monotonous flood basalt lavas that form through a dynamic pattern of eruptive pulses separated b…

Initial Cenozoic magmatic activity in East Africa: new geochemical constraints on magma distribution within the Eocene continental flood basalt province Open
The initial interaction between material rising from the African Large Low Shear Velocity Province and the African lithosphere manifests as the Eocene continental large igneous province (LIP), centred on southern Ethiopia and northern Keny…

PiAutoStage: An Open‐Source 3D Printed Tool for the Automatic Collection of High‐Resolution Microscope Imagery Open
We have created an open‐source 3D printable microscope automatic stage and integrated camera system capable of providing a means for imaging microscope slides—the PiAutoStage. The PiAutoStage was developed to interface with the high‐qualit…
