TL;DR: The San Pedro-Pellado volcanic complex is located at 36°S in the Chilean Andes as discussed by the authors, and the eruptive rocks of the complex record the development and collapse of a caldera followed by voluminous, largely basaltic andesite, volcanism.
Abstract: The San Pedro-Pellado volcanic complex is located at 36° S in the Chilean Andes. The eruptive rocks of the complex record the development and collapse of a caldera, followed by voluminous, largely basaltic andesite, volcanism. At each stage of evolution, crystal fractionation was accompanied by variable degrees of contamination and mixing. Large variations in incompatible element ratios cannot be produced by closed system evolution. Correlations between indices of differentiation and incompatible element ratios, together with high δ 18O values, indicate that basaltic andesites have assimilated crust to generate the evolved volcanic rocks at San Pedro-Pellado. Even in the most mafic rocks, however, incompatible element characteristics are variable as a result of source heterogeneity and deep level processes. The restricted ranges in isotope ratios of Sr, Nd and Pb among San Pedro-Pellado rocks are due to the small contrast in isotopic compositions between magma and wallrock. Three source components are recognized as contributing to parental magmas at San Pedro-Pellado. Although the relative contributions of each cannot be quantified, the volumetrically dominant source component is the sub-arc asthenospheric mantle (MORB source). The major source of LILE is thought to be slab-derived fluids which modified the sub-arc mantle. Other incompatible elements may also have been enriched by interaction with the continental lithosphere (mantle and/or lower crust) during ascent.

TL;DR: In this article, the trace element contents of micro-inclusion-bearing fibrous diamonds from Botswana were studied using neutron activation analysis and the major element composition of the fluids within individual diamonds was found to be uniform, but a significant compositional variation exists between different diamond specimens.

TL;DR: In this article, U-series disequilibria are presented for Holocene samples from the Canary Islands and interpreted with special emphasis on the separate roles of plume vs. lithospheric melting processes.

TL;DR: In this paper, it was shown that CO2 bubbles are enriched in deep-sea basalts that are also enriched in light rare earth and incompatible elements, and that this enrichment probably results from a unique deep mantle origin of such melts but may have been modified by CO 2 bubbles rising in shallow magma chambers.
Abstract: Vesicles and included CO2are enriched in deep-sea basalts that are also enriched in light rare earth and incompatible elements. This enrichment probably results from a unique deep mantle origin of such melts but may have been modified by CO2 bubbles rising in shallow magma chambers.
