Post-collision, shoshonitic volcanism on the Tibetan Plateau: implications for convective thinning of the lithosphere and the source of ocean island basalts
Simon Turner,N. O. Arnaud,J. Liu,Nick Rogers,Chris J. Hawkesworth,Nigel Harris,Simon P. Kelley,P. van Calsteren,W. Deng +8 more
TL;DR: The dominant lavas are pyroxene and plagioclase-phyric shoshonites with subordinate occurrences of dacites and rhyolites as mentioned in this paper, which are characterized by relatively low TiO2, AI2O3 and Fe^Os, and high.A&^Q coupled with variable abundances of compatible trace elements and very high contents of incompatible trace elements.
Journal ArticleDOI
U-Th isotopes in arc magmas: Implications for element transfer from the subducted crust
TL;DR: The low average uranium/thorium ratios of bulk crust primarily reflect different crustal generation processes in the Archaean.
Journal ArticleDOI
Magma Generation at a Large, Hyperactive Silicic Volcano (Taupo, New Zealand) Revealed by U–Th and U–Pb Systematics in Zircons
Bruce L. A. Charlier,Colin J. N. Wilson,Jacob B. Lowenstern,Stephen Blake,P. van Calsteren,Jon P. Davidson +5 more
TL;DR: The model-age spectra, coupled with zircon-dissolution modelling, highlight contrasts between short-term silicic magma generation at Taupo, by bulk remobilization of crystal mush and assimilation of metasediment and/or silicics plutonic basement rocks, and the longer-term processes of fractionation from crustally contaminated mafic melts as mentioned in this paper.
Journal ArticleDOI
Continental mantle lithosphere, and shallow level enrichment processes in the Earth's mantle
TL;DR: In this article, trace element and isotope data on mantle xenoliths, lamproites and kimberlites, and on selected continental flood basalts are integrated to develop a model for the continental mantle lithosphere.
Journal ArticleDOI
Mantle enrichment processes
TL;DR: A review of trace element data in both within-plate basalts and mantle xenoliths suggests that at least two enrichment processes are active within the upper mantle as mentioned in this paper, consistent with the migration of small volume silicate melts with ‘basanitic’ trace element distribution patterns, whereas the other is characterized by relatively high eSr, Rb/Sr and K/Ti ratios.
