TLDR
In this article, U-series disequilibria are presented for Holocene samples from the Canary Islands and interpreted with special emphasis on the separate roles of plume vs. lithospheric melting processes.About:

The circum-Mediterranean anorogenic Cenozoic igneous province
Michele Lustrino,Marjorie Wilson +1 more
TL;DR: In this article, a comprehensive review of published and new major and trace element and Sr-Nd-Pb isotopic data (more than 7800 samples) for the magmatic rocks, a common sub-lithospheric mantle source component is identified for most of the region.
Journal ArticleDOI
Diffusion Data in Silicate Melts
TL;DR: A review of the literature on diffusion in simple-system melts can be found in this article, with about 3600 entries of individual diffusivity values calculated from ab initio and molecular dynamics methods.

Oceanic Island Basalts and Mantle Plumes: The Geochemical Perspective
TL;DR: Mantle plumes are usually, but not always, chemically distinct from the mid-ocean ridge basalt (MORB) and may be rooted in the core-mantle boundary and begin with large voluminous heads triggering massive eruptions or be headless and arise in the midmantle as discussed by the authors.

Cenozoic intraplate volcanism on New Zealand: Upwelling induced by lithospheric removal
Kaj Hoernle,James D. L. White,P. van den Bogaard,Folkmar Hauff,D.S. Coombs,Reinhard Werner,Christian Timm,Dieter Garbe-Schönberg,A. Reay,Alan Cooper +9 more
TL;DR: In this paper, the first-order cause of melting is inferred to be decompression melting in the garnet stability field of upwelling asthenosphere, triggered by removal (detachment) of different parts of the subcontinental lithospheric keel throughout the Cenozoic.

Combined Trace Element and Pb-Nd–Sr-O Isotope Evidence for Recycled Oceanic Crust (Upper and Lower) in the Iceland Mantle Plume
TL;DR: In this paper, the results of a comprehensive major element, trace element and Sr-Nd-Pb-O isotopic study of postglacial volcanic rocks from the Neovolcanic zones on Iceland were presented.

An analysis of the variation of ocean floor bathymetry and heat flow with age
Barry Parsons,John G. Sclater +1 more
TL;DR: In this paper, a simple cooling model and the plate model were proposed to account for the variation in depth and heat flow with increasing age of the ocean floor. But the results were limited to the North Pacific and North Atlantic basins.
Journal ArticleDOI
Nb and Pb in oceanic basalts: new constraints on mantle evolution
TL;DR: In this paper, the authors proposed a new constraint on mantle composition: the differentiated part of the mantle, chemically depleted after separation of the major portion of the continental crust, was subsequently internally rehomogenized.
Journal ArticleDOI
Lead isotopic study of young volcanic rocks from mid-ocean ridges, ocean islands and island arcs
TL;DR: Lead isotopic compositions of young volcanic rocks from different tectonic environments have distinctive characteristics their differences are evaluated within the framework of global tectonics and mantle differentiation Ocean island leads are in general more radiogenic than mid-ocean ridge basalt (morb) leads as discussed by the authors.
Journal ArticleDOI
Hotspots and Mantle Plumes' Some Phenomenology
TL;DR: In this article, the authors examined the available data, mainly topography, geoid, and heat flow, describing hotspots worldwide to constrain the mechanisms for swell uplift and to obtain fluxes and excess temperatures of mantle plumes.

Partial melting of dry peridotites at high pressures: Determination of compositions of melts segregated from peridotite using aggregates of diamond
Kei Hirose,Ikuo Kushiro +1 more
TL;DR: In this article, the compositions of melts formed by partial melting of two relatively fertile spinel lherzolites were determined at pressures between 10 and 30 kbar under dry conditions using a layer of diamond aggregates sandwiched between peridotite layers.
