DESCRIPTION:The Turkana Depression is a broad\, topographically-subdued\, 
 region between the elevated Ethiopian and East African Plateaus. The Depre
 ssion is unique in East Africa for being host to a NW-SE-trending failed M
 esozoic (Anza) rift system through which the near-orthogonal\, N-S-trendin
 g East African Rift subsequently developed. Whether the Depression’s low
 -lying nature is a result of a significantly thinned crust instigated by i
 ts multiple rifting phases\, or instead due to a lack of dynamic mantle su
 pport is debated. Also poorly understood is the extent to which Cenozoic r
 ifting and magmatism have developed across the Depression during the linka
 ge of other comparatively narrow East African Rift zones to the north and 
 south. Utilising data from the 2019-2021 Turkana Rift Arrays Investigating
  Lithospheric Structure project and surrounding networks\, receiver functi
 on analysis and its joint inversion with surface-waves\, are used to probe
  Moho architecture and the lithosphere-asthenosphere system.
