Recycled ocean crust and sediment in Indian Ocean MORB
TLDR
In this paper, the authors show the first case of highly significant correlations of Nb/U, Ba/Nb and Ba/Th with87Sr/86Sr for Indian Ocean mid-ocean ridge basalts and confirm and strengthen a previously detected correlation with Ce/Pb (or Nd/PB) in nine hand picked MORB glasses from the Central Indian and Carlsberg Ridge.About:

The mean composition of ocean ridge basalts
TL;DR: In this article, the mean composition of mid-ocean ridge basalts (MORB) is determined using a global data set of major elements, trace elements, and isotopes compiled from new and previously published data.

Sampling mantle heterogeneity through oceanic basalts: Isotopes and trace elements
TL;DR: Hofmann et al. as discussed by the authors reviewed the recent advances in the field of mantle geology, geophysics, and geochemistry using seismic mantle tomography, and concluded that the established views of the mantle being engaged in simple two-or single-layer convection are becoming obsolete.
Journal ArticleDOI
Hafnium isotope evidence for ‘conservative’ element mobility during subduction zone processes
TL;DR: In this paper, a detailed Hf isotope study of oceanic arc lavas and paired arc/back-arc settings has been conducted and it was shown that the high field strength elements are always displaced significantly from their co-existing back-arc spreading centres which can be considered to sample the local mantle.
Journal ArticleDOI
A hafnium isotope and trace element perspective on melting of the depleted mantle
TL;DR: Salters et al. as discussed by the authors used high-precision rare earth element and trace element data on mid-ocean ridge basalts (MORB) from the Pacific Ocean basin.

Chemical and isotopic systematics of oceanic basalt : implications for mantle composition and processes
TL;DR: In this article, trace-element data for mid-ocean ridge basalts and ocean island basalts are used to formulate chemical systematics for oceanic basalts, interpreted in terms of partial-melting conditions, variations in residual mineralogy, involvement of subducted sediment, recycling of oceanic lithosphere and processes within the low velocity zone.

The continental crust: Its composition and evolution
TL;DR: In this paper, the authors describe the composition of the present upper crust and deal with possible compositions for the total crust and the inferred composition of lower crust, and the question of the uniformity of crustal composition throughout geological time is discussed.

Approximation of terrestrial lead isotope evolution by a two-stage model
J.S. Stacey,Jan Kramers +1 more
TL;DR: In this paper, a two-stage model for terrestrial lead isotope evolution is proposed, which permits the age of the earth to be that of the meteorite system and also yields good model ages for samples of all ages.
Journal ArticleDOI
Chemical differentiation of the Earth: the relationship between mantle, continental crust, and oceanic crust
TL;DR: In this paper, the average chemical compositions of the continental crust and the oceanic crust (represented by MORB), normalized to primitive mantle values and plotted as functions of the apparent bulk partition coefficient of each element, form surprisingly simple, complementary concentration patterns.
