Seismic characteristics of sediment drifts: An example from the Agulhas Plateau, southwest Indian Ocean [PDF]

, 2001
Sediment drifts provide information on the palaeoceanographic development of a region. Additionally, they may represent hydrocarbon reservoirs. Because of this, sediment drift investigation has increased over the last few years. Nevertheless, a number of

Contrasting geophysical and geochemical signatures of a volcano at the axis of the Wharton Fossil Ridge (N-E Indian Ocean)

, 1999
International audienceThe Styx volcano is a prominent seamount (20-30 km diameter, 2500 m high) located at the axis of the Wharton fossil spreading center (N-E Indian Ocean), where seafloor spreading stopped 40 Ma ago.

Sea Beam Survey of an Active Strike-Slip Fault: The San Clemente Fault in the California Continental Borderland [PDF]

, 1989
The San Clemente fault, located in the California Continental Borderland, is an active, northwest trending, right-lateral, wrench fault. Sea Beam data are used to map the major tectonic landforms associated with active submarine faulting in detail ...

Review of Asymmetric Seafloor Spreading and Oceanic Ridge Jumps in the South China Sea

Journal of Marine Science and Engineering
Seafloor spreading is an important cornerstone of the theory of plate tectonics. Asymmetric seafloor spreading and oceanic ridge jumps are common phenomena in this process and play important roles in controlling oceanic crust accretion, regional ...

Formation Waters Delineate Diverse Hydrogeologic Conditions at a Plate Scale: Eastern Flank of the Juan de Fuca Ridge

Geochemistry, Geophysics, Geosystems, 2022
The chemical composition of formation waters within the upper basaltic crust were calculated or measured at 24 sites on the northwest portion of the Juan de Fuca (JDF) Plate using data from sediment pore waters, scientific boreholes, and seafloor springs.

Hydrothermal activity and magma genesis along a propagating back-arc basin: Valu Fa Ridge (southern Lau Basin) [PDF]

, 2006
Valu Fa Ridge is an intraoceanic back-arc spreading center located at the southern prolongation of the Lau basin. Bathymetric observations as well as detailed sampling have been carried out along the spreading axis in order to trace hydrothermal and ...

Geomorphological Features and Formation Process of Abyssal Hills and Oceanic Core Complexes Linked to the Magma Supply in the Parece Vela Basin, Philippine Sea: Insights from Multibeam Bathymetry Analysis

Journal of Marine Science and Engineering
Based on the new high-resolution multibeam bathymetry data collected by the “Dongfanghong 3” vessel in 2023 in the Parece Vela Basin (PVB) and previous magnetic anomaly data, we systematically analyze the seafloor topographical changes of abyssal hills ...

Constraining the Jurassic extent of Greater India: Tectonic evolution of the West Australian margin [PDF]

, 2012
Alternative reconstructions of the Jurassic northern extent of Greater India differ by up to several thousand kilometers. We present a new model that is constrained by revised seafloor spreading anomalies, fracture zones and crustal ages based on ...

Active Long-Lived Faults Emerging Along Slow-Spreading Mid-Ocean Ridges [PDF]

Oceanography, 2012
In the classic mid-ocean ridge model, new seafloor is generated through a combination of magmatic diking feeding lava flows at the spreading axis, and the formation of short-offset, high-angle normal faults that dip toward the axis.
