320,000 years of interaction between a fast-spreading ridge and nearby seamounts monitored using major, trace and isotope composition data from oceanic basalts: Zoom at 15.6°N on the East Pacific Rise

Autor: Berengere Mougel, Arnaud Agranier, Pascal Gente, Christophe Hemond

Publikováno v: Data in Brief, Vol 44, Iss , Pp 108550- (2022)

Basaltic samples were collected by the French submersible ``Nautile'' during the “Parisub” cruise (2010, R/V L'Atalante, Ifremer) along a 25 km long sampling profile crossing perpendicularly the current axis of the East Pacific Rise at 15.6°N, a

High‐Resolution Isotopic Variability Across EPR Segment 16°N: A Chronological Interpretation of Source Composition and Ridge‐Seamount Interaction

Autor: Berengere Mougel, Arnaud Agranier, Christophe Hemond, Pascal Gente

Publikováno v: Geochemistry, Geophysics, Geosystems, Vol 22, Iss 10, Pp n/a-n/a (2021)

Abstract A high‐resolution sampling profile constituted of 52 basalt samples from across the East Pacific Rise (EPR) was investigated. These samples provide a unique opportunity to study the coeval recording of isotopic signals derived from sub‐m

Dyking at EPR 16°N hypermagmatic ridge segment: Insights from near-seafloor magnetics

Autor: Jérôme Dyment, Morgane Le Saout, Chie Honsho, Florent Szitkar, Pascal Gente

Publikováno v: Earth and Planetary Science Letters. 453:288-297

High-resolution, near-seafloor magnetic data have been acquired over the 16°N hypermagmatic segment of the East-Pacific Rise using an Autonomous Underwater Vehicle. This survey proves to be ideal to test the relative efficiency of various inversion

Seafloor slopes at mid-ocean ridges from submersible observations and implications for interpreting geology from seafloor topography

Autor: Pascal Gente, Neil C. Mitchell, Maurice A. Tivey

Publikováno v: Earth and Planetary Science Letters. 183:543-555

Observations from 145 submersible dives are used to create a database of mid-ocean ridge scarp topography and lithology. Seafloor lithologies are classified into extrusives, basaltic talus, dykes, gabbros and serpentinites, and the dive locations are
