Observational and theoretical studies of the dynamics of mantle plume–mid‐ocean ridge interaction
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 …

Temperatures in ambient mantle and plumes: Constraints from basalts, picrites, and komatiites
Several methods have been developed to assess the thermal state of the mantle below
oceanic ridges, islands, and plateaus, on the basis of the petrology and geochemistry of …

Ambient and excess mantle temperatures, olivine thermometry, and active vs. passive upwelling
Mantle temperatures provide a key test of the mantle plume hypothesis, and olivine-liquid
equilibria provide perhaps the most certain means of estimating mantle temperatures. Here …

The role of pyroxenite in basalt genesis: Melt‐PX, a melting parameterization for mantle pyroxenites between 0.9 and 5 GPa
Geochemical and isotopic data suggest that the source regions of oceanic basalts may
contain pyroxenite in addition to peridotite. In order to incorporate the wide range of …

Mantle potential temperatures at Hawaii, Iceland, and the mid‐ocean ridge system, as inferred from olivine phenocrysts: Evidence for thermally driven mantle plumes
KD Putirka - Geochemistry, Geophysics, Geosystems, 2005 - Wiley Online Library
Temperature differences between lavas erupted at ocean islands and mid‐ocean ridges are
crucial to documenting the existence of mantle plumes. Olivines are useful for T estimation …

Reykjanes Ridge evolution: Effects of plate kinematics, small-scale upper mantle convection and a regional mantle gradient
Abstract The Reykjanes Ridge is a key setting to study plate boundary processes overlaid
on a regional mantle melting anomaly. The ridge originated as one arm of a ridge-ridge …

The link between volcanism and deglaciation in Iceland
Temporal variation in the eruption rate and lava composition in the rift zones of Iceland is
associated with deglaciation. Average eruption rates after the end of the last glacial …

The smoothness and shapes of chondrite-normalized rare earth element patterns in basalts
The customary practice for displaying REE abundances is to normalize them to chondritic
abundances and then to plot these normalized abundances in order of atomic number, Z …

Flow and melting of a heterogeneous mantle: 1. Method and importance to the geochemistry of ocean island and mid-ocean ridge basalts
Understanding the partial melting process is key to our ability to relate geochemical
characteristics of hotspot and mid-ocean ridge lavas to the dynamics and chemical structure …

Compositional trends of Icelandic basalts: Implications for short–length scale lithological heterogeneity in mantle plumes
Lithological variations in the mantle source regions under mid‐ocean ridges and ocean
islands have been proposed to play a key role in controlling melt generation and basalt …
