rock emplacements which include continental flood basalts and associated intrusive rocks …

Dynamic processes controlling evolution of rifted basins

PA Ziegler, S Cloetingh - Earth-Science Reviews, 2004‏ - Elsevier
The extension of the lithosphere, controlling the development of rifted basins, is driven by a
combination of plate-boundary forces, frictional forces exerted on the base of the lithosphere …

Geochemical fingerprinting of oceanic basalts with applications to ophiolite classification and the search for Archean oceanic crust

JA Pearce - Lithos, 2008‏ - Elsevier
Two geochemical proxies are particularly important for the identification and classification of
oceanic basalts: the Th–Nb proxy for crustal input and hence for demonstrating an oceanic …

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 …

Heterogeneous mantle domains: signatures, genesis and mixing chronologies

SR Hart - Earth and Planetary Science Letters, 1988‏ - Elsevier
A Srsingle bondNdsingle bondPb isotope data base is available now which includes over
300 samples from some 43 oceanic islands or island groups. This data base supports the …

The source regions of ocean island basalts

DAN McKenzie, RK O'NIONS - Journal of petrology, 1995‏ - academic.oup.com
The geochemical modelling of many small-volume continental magmas shows that their
source regions must have been depleted by basalt formation, and later enriched by the …

Cratons, mobile belts, alkaline rocks and continental lithospheric mantle: the Pan-African testimony

R Black, JP Liégeois - Journal of the Geological Society, 1993‏ - lyellcollection.org

Regionally distinctive sources of depleted MORB: Evidence from trace elements and H2O

P Michael - Earth and Planetary Science Letters, 1995‏ - Elsevier
The sources of depleted mid-ocean ridge basalts (N-MORB) worldwide are regionally
distinctive in that they share incompatible element ratios with spatially associated, enriched …

Incompatible trace elements in OIB and MORB and source enrichment in the sub-oceanic mantle
