The Ethiopian region records about one billion years of geological history. The first event
was the closure of the Mozambique ocean between West and East Gondwana with the …

Porphyry deposits arguably represent the most economically important class of nonferrous
metallic mineral resources. These magmatic-hydrothermal deposits are characterized by …

Continental flood basalts are often considered as fossil evidence of mantle plume heads
im**ing on the lithosphere, and have been related to continental breakup,,. Many of these …

The Ethiopian plateau is made up of several distinct volcanic centres of different ages and
magmatic affinities. In the NE, a thick sequence of 30 Ma flood basalts is overlain by the 30 …

Petrological and geochemical data are reported for basalts and silicic peralkaline rocks from
the Quaternary Gedemsa volcano, northern Ethiopian rift, with the aim of discussing the …

Abstract Cenozoic magmatism in East Africa results from the interplay between lithospheric
extension and material upwelling from the African Large Low Shear Velocity Province …

Picritic lava flows near Lijiang in the late Permian Emeishan flood basalt province are
associated with augite-phyric basalt, aphyric basalt, and basaltic pyroclastic units. The …

Abstract Magmatic Fe-Ni-Cu±platinum-group element (PGE) sulfide deposits form when
mantle-derived mafic and ultramafic magmas become saturated in sulfide and segregate …

The Main Ethiopian Rift (MER) has a complex structural pattern composed of southern,
central, and northern segments. Ages of onset of faulting and volcanism apparently indicate …
