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 …

The magmatic and magmatic-hydrothermal evolution of felsic igneous rocks as seen through Nb-Ta geochemical fractionation, with implications for the origins of rare …
Abstract Despite Nb and Ta being considered as 'geochemical twins', most Ta mineral
deposits are associated with muscovite-bearing peraluminous granites and related …

Geochemistry of CI chondrites: Major and trace elements, and Cu and Zn isotopes
In order to check the heterogeneity of the CI chondrites and determine the average
composition of this group of meteorites, we analyzed a series of six large chips (weighing …

Chemical variations and regional diversity observed in MORB
An assemblage of MORB analyses (n= 792 samples), including a suite of new, high-
precision LA-ICP-MS measurements (n= 79), has been critically compiled in order to provide …

Temperature, pressure, and composition of the mantle source region of Late Cenozoic basalts in Hainan Island, SE Asia: a consequence of a young thermal mantle …
Abstract Basaltic lavas from Hainan Island near the northern edge of the South China Sea
have an age range of between late Miocene (about 13 Ma) and Holocene, with a peak age …

The Bikou basalts in the northwestern Yangtze block, South China: Remnants of 820–810 Ma continental flood basalts?
Mantle plume or superplume activities have often been invoked as a cause for the breakup
of the Neoproterozoic supercontinent Rodinia. However, associated Neoproterozoic …

Recycled crust controls contrasting source compositions of Mesozoic and Cenozoic basalts in the North China Craton
We explore Fe/Mn and Nb/Ta ratios of basalts as potential tracers for differentiating melts of
recycled mafic crustal lithologies from peridotitic melts. Trace elements and Fe/Mn ratios of …

Mobilization of Ti–Nb–Ta during subduction: evidence from rutile-bearing dehydration segregations and veins hosted in eclogite, Tianshan, NW China
Field evidence from the western Tianshan subduction complex in northwestern China
indicates that the high field strength elements Ti, Nb, and Ta were mobilized and thereby …

Between carbonatite and lamproite—diamondiferous Torngat ultramafic lamprophyres formed by carbonate-fluxed melting of cratonic MARID-type metasomes
New U–Pb perovskite ages reveal that diamondiferous ultramafic lamprophyre magmas
erupted through the Archean crust of northern Labrador and Quebec (eastern Canada) …
