An immense shield volcano within the Shatsky Rise oceanic plateau, northwest Pacific Ocean
Most oceanic plateaux are massive basaltic volcanoes. However, the structure of these volcanoes, and how they erupt and evolve, is unclear, because they are remote and submerged beneath the oceans. Here we use multichannel seismic profiles and rock samples taken from Integrated Ocean Drilling Program core sites to analyse the structure of the Tamu Massif, the oldest and largest edifice of the S...
متن کاملThe Shatsky Rise oceanic plateau structure from two-dimensional multichannel seismic refl ection profi les and implications for oceanic plateau formation
The Shatsky Rise is one of the largest oceanic plateaus, a class of volcanic features whose formation is poorly understood. It is also a plateau that was formed near spreading ridges, but the connection between the two features is unclear. The geologic structure of the Shatsky Rise can help us understand its formation. Deeply penetrating two-dimensional (2-D) multichannel seismic (MCS) refl ect...
متن کاملSeismic tomography of Shatsky Rise by adaptive importance sampling
[1] We present results from a wide-angle seismic refraction survey over Shatsky Rise, a large oceanic plateau in the northwestern Pacific. A new Monte Carlo sampling scheme is developed to explore comprehensively the model space of crustal velocity structure by joint refraction and reflection seismic tomography. The new scheme, which is founded on the notion of adaptive importance sampling, is ...
متن کاملNew seismic imaging of some tectonic zones in the Iranian Plateau
The Iranian Plateau is characterized by diverse tectonic domains, including the continental collisions (e.g. the Zagros and Alborz Mountains) and oceanic plate subduction (e.g. Makransubduction zone). To derive a detailed image of the crust–mantle (Moho) and lithosphere–asthenosphere (LAB) boundaries in some tectonically units of the Iranian Plateau, we used a large number of S receiver functio...
متن کاملReorganization of the Pacifi c-Izanagi-Farallon triple junction in the Late Jurassic: Tectonic events before the formation of the Shatsky Rise
It has been suggested that the Shatsky Rise oceanic plateau formation began simultaneously with a reorganization of spreading at a triple junction bordering the northern Pacifi c plate, and this coincidence has led to speculation about the connections between the two events. We present new marine geophysical data that constrain the seafl oor spreading history of the Pacifi c-Izanagi-Farallon tr...
