    Abstract. This paper focuses on the authigenic mineralization processes acting on "Tufo Rosso a Scorie Nere" (TRS), i.e. one of the main pyroclastic units of the Vico stratovolcano (Latium, Italy). The pyroclastic deposits appear in general massive and made of "black vitreous vesiculated juvenile scoriae", immersed in an ashy matrix lithified after zeolitization processes.

  • Silica‐associated lung disease: An old‐world exposure

    2019-9-13Silica (silicon dioxide, SiO 2) is a naturally occurring mineral that accounts for 59% of the mass of the earth's crust and is the main constituent of more than 95% of rocks. Historically, most workers at risk of silicosis were those who encountered it in its natural environment, such as miners, tunnels and quarry workers.
