s-Processing from MHD-induced mixing and isotopic abundances in presolar SiC grains
S. Palmerini, O. Trippella, M. Busso +4
In the past years the observational evidence that s-process elements from Sr to Pb are produced by stars ascending the socalled Asymptotic Giant Branch (or AGB) could not be explai…
Experimental constraints on the rheology, eruption and emplacement dynamics of analog lavas comparable to Mercury's northern volcanic plains
Francesco Vetere, Stefano Rossi, Olivier Namur +6
We present new viscosity measurements of a synthetic silicate system considered an analogue for the lava erupted on the surface of Mercury. In particular, we focus on the northern…
Exponential Decay Of Concentration Variance During Magma Mixing: Robustness Of A Volcanic Chronometer And Implications For The Homogenization Of Chemical Heterogeneities In Magmatic Systems
Stefano Rossi, Maurizio Petrelli, Daniele Morgavi +4
The mixing of magmas is a fundamental process in the Earth system causing extreme compositional variations in igneous rocks. This process can develop with different intensities bot…
High spatial resolution trace element determination of geological samples by laser ablation quadrupole plasma mass spectrometry: implications for glass analysis in volcanic products
Maurizio Petrelli, Kathrin Laeger, Diego Perugini
Increasing the spatial resolution of Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) is a challenge in microanalysis of geological samples. Smaller sizes fo…
Solving petrological problems through machine learning: the study case of tectonic discrimination using geochemical and isotopic data
Maurizio Petrelli, Diego Perugini
Machine learning methods are evaluated to study the intriguing and debated topic of discrimination among different tectonic environments using geochemical and isotopic data. Volcan…
Water-enhanced interdiffusion of major elements between natural shoshonite and high-K rhyolite melts
Diego González-García, Harald Behrens, Maurizio Petrelli +4
The interdiffusion of six major elements (Si, Ti, Fe, Mg, Ca, K) between natural shoshonite and a high-K calc-alkaline rhyolite (Vulcano island, Aeolian archipelago, Italy) has bee…
