TL;DR: Petrological and geochemical data for a suite of brought down in a subducting slab at a former convergent plate ultramafic xenoliths (lherzolites and wehrlites) from La Grille margin is presented in this article.

TL;DR: In this article, Trace element analyses have been made of large zircon crystals from rocks of alkaline affinities by ion microprobe and the partition coefficients for the light rare earth elements (LREEs), between zircons and melt or whole rock, must therefore be significantly lower than those calculated using bulk analyses.

TL;DR: In this paper, an ion microprobe analysis of speleothems reveals that annual to sub-annual variations in element chemistry exist at five, shallow western European cave sites (Crag Cave, County Kerry and Ballynamintra, County Waterford, Ireland; Uamh an Tartair, Sutherland, Scotland; Grotte Pere-Noel, Belgium; Grotta di Ernesto, NE Italy) with widely varying climatic, geomorphic and geological settings.

TL;DR: In this article, the LA-ICP-MS U/Pb geochronology of rutile has been analyzed using a 213 nm Nd:YAG laser coupled to a quadrupole ICP-MS.

TL;DR: In this article, the authors explored the use of Mn in apatite as an oxybarometer in intermediate and silicic igneous rocks and found that increased Mn concentrations in apats correlate with decreasing Fe2O3 (Fe3+) and Mn in the whole-rock and likely reflect increased Mn2+/Mn3+ and greater compatibility of Mn2+, relative to Mn3+ in apatis under reduced conditions.
