to investigate the xenolith protolith and metamorphic ages using in situ zircon U–Pb geochronology, together with whole-rock geochemistry, thermobarometry and zircon Hf isotope geochemistry. Details ...
spot of between 0·38 and 0·50‰ at the 2σ level. Lu–Hf isotope measurement Lu–Hf isotope analysis was carried out by LA-MC-ICP-MS, using a Nu Plasma HR multi-collector mass spectrometer at the Department ...
selected samples were imaged in thin section using back-scattered electrons (BSE) with an FEI Quanta 400f field-emission scanning electron microscope (SEM) at the University of California, Santa Barbara ...
magmas thus should be treated cautiously as tracers for mantle isotopic compositions. Mixing between mafic magmas and accessory-mineral rich syenites can selectively enrich incompatible trace elements ...
melt. The rims of this clinopyroxene were preferentially sampled in trace element analyses by LA-ICP-MS. The six Canary Islands clinopyroxenes that were selected for determination of mineral–melt ...
contamination before each analysis, and each spot was focused using a primary ion beam of 1.5–1.9 nA with a diameter of ∼25 μm. SHRIMP spots were made on both inherited cores and rims to determine the level ...
