Easter Island has developed around three volcanoes—Poike, an older (3 m.y.) strato-volcano, Rano Kau, a caldera, and the fissure complex of Terevaka and its associated cones. The lavas show a wide compositional spread from tholeiites and olivine tholeiites to hawaiites, mugearites, benmoreites, trachytes and rhyolites (comendites). Hawaiite is by far the most abundant rock type and trachytes and rhyolites are relatively rare. Intermediate and acid rocks are concentrated in the southwestern part… Expand
A geochemical and petrological study of the Tertiary minor intrusions of Rhum, northwest Scotland
The Rhum minor intrusion suite is petrographically and compositionally variable, the majority of the basic rocks are aphyric dolerites but olivine phyric (picritic) and plagioclase phyric (bigExpand
Geochemistry of volcanic rocks from the Tetagouche Group, Bathurst, New Brunswick, Canada
The volcanic rocks of the Tetagouche Group are predominantly dacitic to rhyolitic pyroclastics and lavas; mafic alkaline and tholeiitic volcanic rocks are less abundant. Lavas representing theExpand
Chronology, chemistry, and origin of trachytes from Hualalai Volcano, Hawaii
[1] Hualalai Volcano is unique among Hawaiian volcanoes in that it possesses a relatively high proportion of evolved, trachytic lavas that were erupted at the beginning of the alkalic, postshieldExpand
Late-orogenic alkaline/subalkaline Silurian volcanism of the Skomer Volcanic Group in the Caledonides of south Wales
Basaltic, andesitic and rhyolitic volcanism was widespread during Ordovician time in the Welsh, Basin. Minor Silurian volcanic rocks occur in the Welsh Borderland and in Pembrokeshire (Dyfed), whereExpand

Geochemical evolution of the Juan Fernandez Islands, SE Pacific
The two main islands of the Juan Fernandez group, some 180 km apart are intra-plate volcanoes related to a single hot spot. K-Ar determinations suggest an age difference of c. 3 Ma which is in accordExpand

Volcanology and eruptive styles of Barren Island: an active mafic stratovolcano in the Andaman Sea, NE Indian Ocean
Barren Island (India) is a relatively little studied, little known active volcano in the Andaman Sea, and the northernmost active volcano of the great Indonesian arc. The volcano is built ofExpand

Easter Island (Rapa Nui, Chile) is an intraoceanic volcanic island on the Easter hotspot, ~350 km E of the Eastern Pacific Rise. We match new field data with previously published age andExpand

Aspects of Magmatic Evolution on Reunion Island
TLDR
The chemical data indicate a considerable degree of coherence between the various rock types produced during the different stages of development, and it is concluded that they all stem from essentially the same hypersthene-normative, picritic, primitive magma, generated by partial melting of peridotite in the low-velocity layer of the upper mantle.

Genetic Relations of Oceanic Basalts as Indicated by Lead Isotopes
TLDR
The isotopic composition of lead in oceanic tholeiite suggests that the upper mantle source region of the tholeuite was differentiated from and original mantle material more than 1 billion years ago and that theupper mantle is not homogeneous at the present time. Expand

Isotopic Composition of Lead and Strontium from Ascension and Gough Islands
TLDR
The inter-island differences indicate the existence of regional variations in the uranium-lead and rubidium-strontium ratios of the upper mantle source of these rocks and show that isotope compositions are a means for investigating chemical heterogeneities in the mantle. Expand
