The study of noble gases in oceanic basalts is central to understanding chemical
heterogeneity of the Earth's mantle and origin of the atmosphere. In the terrestrial …

Hot spot–mid‐ocean ridge interactions cause many of the largest structural and chemical
anomalies in Earth's ocean basins. Correlated geophysical and geochemical anomalies are …

When Harry Hess first proposed the theory of seafloor spreading, he imagined that mantle
peridotite upwelling at midocean ridges reacted with water to form a serpentinite oceanic …

The formation of basaltic crust at mid-ocean ridges and ocean islands provides a window
into the compositional and thermal state of the Earth's upper mantle. But the interpretation of …

Subduction zone magmas are characterized by high concentrations of H2O, presumably
derived from the subducted plate and ultimately responsible for melting at this tectonic …

The concentration of carbon in primary mid‐ocean ridge basalts (MORBs), and the
associated fluxes of CO2 outgassed at ocean ridges, is examined through new data …

The radiogenic isotope heterogeneity of oceanic basalts is often assessed using 2D isotope
ratio diagrams. But because the underlying data are at least six dimensional (87Sr/86Sr …

Decades of exploration for venting sites along spreading ridge crests have produced global
datasets that yield estimated mean site spacings of∼ 12–220 km. This conclusion demands …

The Eastern Lau Spreading Center (ELSC) is the southernmost part of the back-arc
spreading axis in the Lau Basin, west of the Tonga trench and the active Tofua volcanic arc …

We use 2‐D numerical models to explore the thermal and mechanical effects of magma
intrusion on fault initiation and growth at slow and intermediate spreading ridges. Magma …
