Earth's heterogeneous mantle: A product of convection-driven interaction between crust and mantle
A Stracke - Chemical Geology, 2012 - Elsevier
Ubiquitous heterogeneity in the Earth's mantle has been documented by numerous
chemical and isotopic analyses of oceanic basalts. Despite the ever-increasing amount of …

Composition of the depleted mantle
VJM Salters, A Stracke - Geochemistry, Geophysics …, 2004 - Wiley Online Library
We present an estimate for the composition of the depleted mantle (DM), the source for mid‐
ocean ridge basalts (MORBs). A combination of approaches is required to estimate the …

Mantle plumes and entrainment: isotopic evidence
SR Hart, EH Hauri, LA Oschmann, JA Whitehead - Science, 1992 - science.org
Many oceanic island basalts show sublinear subparallel arrays in Sr-Nd-Pb isotopic space.
The depleted upper mantle is rarely a mixing end-member of these arrays, as would be …

High precision Hf isotope measurements of MORB and OIB by thermal ionisation mass spectrometry: insights into the depleted mantle
The existing Hf isotope database for mid-ocean ridge basalts (MORB) is limited in both
quantity and precision. Nevertheless, in Hf–Nd isotope space, MORBs show a wide variation …

[PDF][PDF] Origin of back‐arc basin magmas: Trace element and isotope perspectives
The compositions of back-arc basin basalts (BABB) can usefully be viewed as products of
four factors:(1) the composition of inflowing mantle and its preconditioning during flow to the …

Hf-Nd element and isotope perspective on the nature and provenance of mantle and subduction components in Western Pacific arc-basin systems
This paper develops methods for using the integrated study of Hf-Nd element and isotope
covariations to define the nature and provenance of the mantle and subduction inputs to …
