Focus
on ocean islands: An anthology of papers in Nature
Geoscience, 4, 813-900
Forty
years of plume research, p 813
Mantle
dynamics drive the formation of ocean islands
and seamounts in the interior of oceanic plates.
Yet the mechanisms for generating these volcanic
edifices differ from chain to chain, and their
material can be generated at a variety of depths.
Mantle
plumes persevere, pp 816 - 817, Anthony A.
P. Koppers
The ocean floor is littered
with hundreds of thousands of mostly extinct
volcanoes. The origin of at least some of
these seamounts seems to rest with mantle
plumes.
Geodynamics:
Christmas recycling, pp
823 - 824, Sally A. Gibson
The mechanisms for
forming the abundant volcanic islands on ocean
floors are debated. The geochemical signature
of volcanic rocks from the northeast Indian
Ocean suggests that seamounts there formed
from melting recycled ancient continental rocks.
Role
of the deep mantle in generating the compositional
asymmetry of the Hawaiian mantle plume, pp
831 - 838, Dominique Weis, Michael O. Garcia,
J. Michael Rhodes, Mark Jellinek & James
S. Scoates
Volcanoes formed above the Hawaiian
mantle plume exhibit a striking contrast in
the geochemical characteristics of the lavas
erupted at the northern Kea compared with the
southern Loa volcanoes. Isotopic data show
that these trends have persisted for more than
5 million years and may mirror compositional
heterogeneities in the deep mantle.
Geochemical
zoning of volcanic chains associated with Pacific
hotspots, pp 874 - 878, Shichun Huang, Paul
S. Hall & Matthew
G. Jackson
Lavas erupted from volcanoes in the
north of the Hawaiian volcanic island chain
have a different geochemical signature from
those in the south. Analysis of the geochemistry
of lavas erupted in the Samoan and Marquesas
volcanic chains reveals similar trends, implying
that the lowermost mantle beneath the southern
Pacific is isotopically enriched.
A
deep mantle origin for the primitive signature
of ocean island basalt, pp 879 - 882, Frédéric
Deschamps, Edouard Kaminski & Paul
J. Tackley
Seismic data have identified large-scale
compositional heterogeneities in Earth's deep
mantle, but their origin is debated. Numerical
modelling demonstrates that seismological and
geochemical constraints on the character of
these heterogeneities can be satisfied if they
are composed of primitive material formed early
in Earth's history.
Origin
of Indian Ocean seamount province by shallow
recycling of continental lithosphere, pp 883 - 887, K. Hoernle, F. Hauff,
R. Werner, P. van den Bogaard, A. D. Gibbons,
S. Conrad & R.
D. Müller
The origin of the Christmas Island
Seamount Province in the northeast Indian Ocean
is enigmatic. Radiometric dating and isotopic
analysis of volcanic rocks from the seamounts
imply that they were derived from the recycling
of continental lithosphere and brought to the
surface at a mid-ocean ridge.
Geodynamics:
The ups and downs of sediments, Terry
Plank & Peter
E. van Keken
Neither recycled oceanic crust
nor sediments alone can explain the composition
of ocean-island basalts, but how about a mixture
of the two? Recent modelling using the isotopes
of hafnium and neodymium appears to support
this contention.
Volcanism:
Eruptions above mantle shear, Scott D. King
Why broad fields
of volcanism are found in the interior of tectonic
plates is hard to explain. Spatial correlations
between sheared mantle flow and volcanism suggest
that differential motion between surface plates
and the mantle generates upwelling and melt.
Geodynamics:
Surface impact of mantle processes, Philip
A. Allen
Dynamic motions in Earth's mantle can
be expressed at the surface. Rocks and landscapes
beneath the North Atlantic Ocean record surface
uplift driven by pulses of hot material upwelling
in a mantle plume beneath Iceland.
Geodynamics:
East Africa on the rise, Raphaël
Pik
The growth of East Africa's high topography
during the past 30 million years cannot be
explained by typical mountain-building processes.
Numerical modelling shows that much of this
topography formed in response to upwelling
in the underlying mantle.
The
many surface expressions of mantle dynamics, Jean Braun
Earth's topography
is attributed to the interactions of the tectonic
plates, but flow within the mantle also contributes
to surface uplift and subsidence. An overview
of recent research indicates that mantle-induced
dynamic topography can be reconstructed by
integrating the geological record with models
of mantle flow.
Role
of recycled oceanic basalt and sediment in
generating the Hf–Nd
mantle array, Catherine Chauvel, Eric Lewin,
Marion Carpentier, Nicholas T. Arndt & Jean-Christophe
Marini
The isotopic composition of oceanic basalts
suggests that they are composed of true recycled
oceanic crust and sediments, which are mixed
with the depleted mantle.
Recycled
gabbro signature in hotspot magmas unveiled
by plume—ridge
interactions, N. A. Stroncik & C. W. Devey
The
geochemistry of lavas erupted at locations
where mantle plumes interact with mid-ocean
ridges reflects the mixing between the two
sources. Analysis of lavas erupted above the
Foundation hotspot, near the Pacific–Antarctic
Ridge, reveal a geochemical signature indicative
of both a primitive mantle plume source and
a recycled oceanic lithosphere source.
Patterns
of intraplate volcanism controlled by asthenospheric
shear, Clinton P. Conrad, Todd A. Bianco, Eugene
I. Smith & Paul
Wessel
Volcanism observed far from plate boundaries,
in the interior of oceanic and continental
plates, may result from flow in the underlying
mantle. Comparison between a numerical model
of mantle flow and the spatial distribution
of intraplate volcanism indicates that rapid
shear motion in the mantle may drive melting
that causes intraplate eruptions.
Spatial
and temporal variability in Hawaiian hotspot
volcanism induced by small-scale convection, Maxim D.
Ballmer, Garrett Ito, Jeroen van Hunen & Paul
J. Tackley
Variations in the volume, geochemistry
and location of volcanism in Hawaii cannot
be explained as the simple consequence of an
underlying mantle plume. A numerical model
of the Hawaiian plume suggests that small-scale
convection in the mantle erodes the base of
the overlying tectonic plate and may help generate
the anomalous volcanism.
Changes
in African topography driven by mantle convection, Robert
Moucha & Alessandro
M. Forte
Africa's topography is characterized
by large-scale uplifted domes and subsided
basins. Numerical simulations of mantle flow
suggest that high topography along Africa's
eastern margin formed as a result of the northward
migration of the tectonic plate over the African
superplume during the past 30 million years.
Ocean
circulation and mantle melting controlled by
radial flow of hot pulses in the Iceland plume,
Heather Poore, Nicky White & John
Maclennan
V-shaped ridges of thickened oceanic
crust above the Iceland plume are thought to
record variations in the convection of the
mantle below. Geochemical analyses of basalt
samples taken from the ridges suggest the thickened
crust formed as the result of blobs of hot
mantle rising up in the underlying plume.
Transient
convective uplift of an ancient buried landscape,
Ross A. Hartley, Gareth G. Roberts, Nicky White & Chris
Richardson
Hot mantle upwelling in the Icelandic
plume has caused episodic uplift of sedimentary
basins located off the northwest coast of Europe.
Reconstruction of river profiles on an ancient
buried landscape constrains the history of
surface uplift and suggests that pulses of
hot plume material spread out at velocities
of 35 cm yr-1. |
