TL;DR: The new PetroGraph software, developed to visualize, elaborate, and model geochemical data for igneous petrology purposes, is able to plot data on several different diagrams, including a large number of classification and “petrotectonic” plots.

TL;DR: In this paper, the mixing process has been simulated by coupling a chaotic advection and a chemical diffusion numerical scheme by considering several trace elements with variable diffusivities, and the results indicate that such a model explains with good approximation the variable correlations among trace elements observed in natural samples.

TL;DR: In this paper, the authors analyzed the mixing/mingling structures of the 13-ka-old Upper Pollara eruption (Salina Island, southern Italy) and compared the results with those obtained from numerical simulations of mixing processes coupling chaotic advection and chemical diffusion.

TL;DR: In this article, geochemical, petrological and fluid-inclusion data, correlated with different generations of pyrope-rich garnet (from medium, to very-coarse-grained in size) allow constraints to be placed on the relative timing of metasomatism and sources of the metasomatic fluid.

TL;DR: In this article, a Taylor-Couette-like experimental setting was used to measure the variation of trace element concentrations along transects crossing the resultant melt column. And the results indicated that the onset of diffusive fractionation processes may strongly influence the patterns of data on inter-elemental diagrams depending on the relative mobility of the different elements.
