Fig. 4From: Interplay of irreversible reactions and deformation: a case of hydrofracturing in the rodingite–serpentinite systemPhotographs, BSE images and photomicrograph of vein-type rodingite, and serpentinite. a Outcrop showing a vein-type rodingite (131018-4A) and tremolite veins in serpentinite derived from the reaction zone (RZ). b Titanite crystal containing ilmenite in its core, which was taken from the rodingite (131018-4A). c Perovskite crystal showing a symplectic texture with diopside, likely implying a pseudomorph after titanite. d Photomicrograph of tremolite veins in serpentinite under crossed polarsBack to article page
