The kinematics of subduction zones shows a variety of settings that can provide clues for
dynamic understandings. Two reference frames are used here to describe the simple 2D …

Although fault and magmatic processes have achieved plate spreading at mid-ocean ridges
throughout Earth's history, discrete rifting episodes have rarely been observed. This paper …

Comprehensive major-, trace-element and rhenium–osmium (Re–Os) isotope data are
presented for abyssal peridotites from Ocean Drilling Program (ODP) Leg 209, in the North …

A fundamental challenge in modern mantle geochemistry is to link geochemical data with
geological and geophysical observations. Most of the early geochemical models involved a …

Melting processes beneath the Mid-Atlantic Ridge were studied in residual mantle
peridotites sampled from a lithospheric section exposed near the Vema Fracture Zone at 11° …

Kane Megamullion, an oceanic core complex near the Mid-Atlantic Ridge (MAR) abutting
the Kane Transform, exposes nearly the full plutonic foundation of the MARK paleo-ridge …

The mechanisms driving plate motion and the Earth's geodynamics are still not entirely
clarified. Lithospheric volumes recycled at subduction zones or emerging at rift zones testify …

At mid-ocean spreading centres, extension can be accommodated by slip on large, long-
lived (1–2 Myr) detachment faults that expose large tracts of lower crustal gabbroic rocks …

We obtained areal variations of crustal thickness, magnetic intensity, and degree of melting
of the sub‐axial upwelling mantle at Thetis and Nereus Deeps, the two northernmost axial …

This paper presents the first detailed geologic map of in situ lower ocean crust; the product
of six surveys of Atlantis Bank on the SW Indian Ridge. This combined with major and trace …
