Journal ArticleDOI
Basalts from Iceland and Along the Reykjanes Ridge: Sr Isotope Geochemistry
TL;DR: Strontium isotope ratios in basalts demonstrate two distinct mantle sources under Iceland and the Reykjanes Ridge as mentioned in this paper, which is the source of most of the Earth's volcanic activity.
Journal ArticleDOI
Hotspot-migrating ridge interaction in the South Atlantic
TL;DR: In this paper, short-wavelength geochemical anomalies in the basaltic layer 2A occur along the South Atlantic mid-ocean ridge opposite Ascension, St Helena and Tristan hotspots, further evidence that preferential subcrustal flow channels develop between mantle upwelling zones (hotspots) and migrating ridge axes.
Journal ArticleDOI
Upper mantle heterogeneities and dynamics
TL;DR: The width of geochemical and residual elevation anomalies along the mid-Ocean Ridge System decrease as both the distance between migrating ridge segments and related hotspots and local geochemical dispersion in the anomalies increase as discussed by the authors.
Journal ArticleDOI
Helium and hydrogen isotopes in ocean-ridge basalts north and south of Iceland
TL;DR: In this paper, the effect of the Icelandic mantle plume on helium isotope rn1ios is observable along the entire length of the Reykjanes Ridge (R = 11−16.1 R A ) and to 70°N on the Kolbeinsey Ridge ( R = 10.3−12 R A ).

Spinels in Mid-Atlantic Ridge basalts: Chemistry and occurrence
TL;DR: In this paper, three groups of spinels have been identified in dredged basalts from the Mid-Atlantic Ridge in the Azores region (30-40°N): (1) magnesiochromites with 0.4-0.5 Cr/(Cr + Al) are most common and characteristic of olivine tholeiites of the region; (2) titaniferous spinels are found in an olivinite basalt with alkali affinities, of local occurrence and evolved in relatively high fugacity of oxygen; (3) chromian
