From: Occurrence and characterization of tremolite asbestos from the Mid Atlantic Ridge
(a) Sample SMA1971-214 observed with polarized light optical microscopy (plane-polarized light). Tremolite (Tmr) fibres with orientation are grouped in sheaf-like clusters: the darkest regions are mainly basal sections while lighter ones are lateral sections. Detail of folded and kinked tremolite by perpendicular overgrowth of another bundle. (b) SEM image of tremolite (Tmr), secondary rounded chlorite (Chl) and late lizardite (Lz) around crystals and filling fractures. (c) SEM image of late lizardite (Lz) domain with tremolite (Tmr) fibres at the border of the sample coated by Mn-oxides (Mn-Ox). (d) The Mn-oxides (Mn-Ox) coating envelops the sample and spreads within.
