Journal of Petrology, Oxford University Press (OUP), 2021, 62 (1), pp.egab004. ⟨10.1093/petrology/egab004⟩
Low-pressure silica polymorphs, e.g. quartz (Qtz), tridymite (Trd), and cristobalite (Crs), are common in silicic magmas, but the conditions of their formation are still unclear. The stability fields of these polymorphs have been determined in the Si

Morphological and chemical characterization of asbestos fibers in solid rocks: Towards an in-situ and combined analytical approach
Autor: Didier Lahondère, Guillaume Wille, Ute Schmidt, Jérémie Silvent, Jéromine Duron, Cédric Duée
Asbestos is a commercial term which refers to six minerals that crystallize as fibrous bundles made of very thin and easily separable fibrils. Asbestos fibers have been exploited for a long time and voluntary added in a very large set of manufactured
