Receiver function analysis is one of the most powerful methods for modeling the subsurface structure beneath a seismograph station. Based on the assumption that similar receiver functions should be observed at stations located close to each other, we can construct a spatial distribution of a seismic velocity interface, such as the Moho discontinuity, to trace the distribution of P-to-S (Ps) con...

Dunites in ophiolites form by pyroxene dissolution and olivine precipitation during melt-peridotite interaction. We present structural geochemical data on peridotites from the Batin region (Wadi Tayin massif) of Oman ophiolite, where an exceptionally large (∼9.5 km long) dunite body was sampled ICDP Drilling Project (BA4A borehole). 900–1,200 m beneath petrological Moho, this is overlain harzbu...

Our knowledge of melt distribution in the lower crust and upper mantle at oceanic fast spreading centers is very limited. Evidence accumulation, sometimes away from axis, has been imaged interpreted Moho East Pacific Rise; but detailed structures these deep magma lenses remains much more difficult to unveil than that shallow axial lens top plutonic crust. Ophiolites offer on-land sections litho...

Abstract Oceanic Transform Faults are one of manifestations the three major plate boundaries and a key tectonic feature oceanic crust. They broadly considered to accommodate strike‐slip displacement along simple vertical faults be largely without magmatic addition. We present first observations from broadband 3D seismic buried, Cretaceous‐aged transform in Gulf Guinea with complex internal arch...
