DOI: 10.1016/j.chemgeo.2017.06.008
Abstract: Abstract The abundance and distribution of halogens (F, Cl) are rarely recorded in kimberlites and therefore their petrogenetic significance is poorly constrained. Halogens are usually present in kimberlite rocks in the structure of phlogopite and… read more here.

DOI: 10.1016/j.epsl.2019.04.021
Abstract: Abstract Primary subduction-related magmas build up modern continental crust and counterbalance massive recycling of crustal material into the deep mantle occurring at this tectonic setting. Melt inclusions in Mg-rich olivine are believed to be the… read more here.

DOI: 10.1016/j.gca.2017.01.054
Abstract: Abstract Olivine-hosted melt inclusions within lava retain important information regarding the lava’s primary magma compositions and mantle sources. Thus, they can be used to infer the nature of the mantle sources of large igneous provinces,… read more here.

DOI: 10.1016/j.gca.2019.03.012
Abstract: Abstract Olivine phenocrysts in basaltic rocks carry valuable mineral-chemical information on early evolution processes in mafic magmatic systems. Fast intra-crystalline diffusion and re-equilibration weakens this potential for major cation constituents of olivine, but the relative… read more here.

DOI: 10.1016/j.gca.2019.05.020
Abstract: Abstract Basaltic volcanism contributes significant fluxes of volatiles (CO2, H2O, S, F, Cl) to the Earth’s surface environment. Quantifying volatile fluxes requires initial melt volatile concentrations to be determined, which can be accessed through crystal-hosted… read more here.
