Abstract Drill sites in the southern Bay of Bengal at 3°N 91°E (International Ocean Discovery Program Expedition 362) have sampled for first time a complete section Nicobar Fan and below to oceanic crust. This generally overlooked part Bengal–Nicobar System may provide new insights into uplift denudation rates Himalayas Tibetan Plateau. The comprises sediment gravity‐flow deposits, mostly turbidites, that alternate with hemipelagite drapes pelagite intervals varying thicknesses....
Abstract The southern Hikurangi subduction zone exhibits significant along‐strike variation in convergence rate and obliquity, sediment thickness and, uniquely, the increasing proximity of to, impingement on, incoming continental Chatham Rise, an ancient Gondwana accretionary complex. There are corresponding changes morphology structure prism. We combine widely spaced multichannel seismic reflection profiles with high resolution bathymetry previous interpretations to characterize history...
The equatorial eastern Indian Ocean hosts a diffuse plate boundary, where widespread deformation accommodates the relative motion between Indian, Australian and Capricorn sub-plates. We integrate IODP Expedition 362 borehole data, which for first time provides an accurate, ground-truthed chronostratigraphy of sedimentary sequence east Ninety East Ridge (NER), with 2D seismic reflection profiles multibeam bathymetry to assess styles faulting NER Sunda subduction zone, timing activity...
Abstract Shallow slip on the plate‐boundary fault during 2004 Mw 9.2 Aceh‐Andaman Earthquake, offshore North Sumatra, has been linked to thick incoming sediments oceanic plate with advanced diagenetic and sediment property changes at depths of boundary development. We couple age control, physical, thermal measurements from International Ocean Discovery Program (IODP) drilling multichannel seismic reflection data reconstruct structure evolution column, up point accretion/subduction....
