We present undercooling (∆T) experiments aimed at investigating the effect of growth kinetics on the textural and compositional evolution of clinopyroxene crystals growing from a high-K basalt erupted during the 2003 paroxysm of Stromboli volcano (Italy). The experiments were performed at P = 350 MP ...

To develop new criteria to distinguish different crystal nucleation mechanisms in silicate melts, we performed crystalliza-tion experiments using a synthetic hydrous (2 wt% H2O) trachybasalt and combined three-dimensional information from synchrotron X-ray computed microtomography with two-dimension ...

Cosmic dust flux during the quaternary
Samuele Ottaviani, Luigi Folco, M. D. Suttle, Rožle Repič, Lucia Mancini, Tommaso Battiston, Stefano Iannini Lelarge, Matteo Masotta

We estimate the cosmic dust flux to Earth through the study of rare micrometeorites that preserve part of their precursor features during atmospheric entry heating, namely unmelted and scoriaceous subtypes. Combining high-precision mass balance measurements, X-ray computed microtomography and scanni ...
