Fig. 7From: Interplay of irreversible reactions and deformation: a case of hydrofracturing in the rodingite–serpentinite systemActivity diagram showing the saturation lines of diopside and tremolite (solid lines) and that of antigorite (broken line), showing the equilibrium conditions of the minerals under constant activity of Si4+. The arrow indicates a change from the equilibrium point A of diopside and antigorite to that B of tremolite and antigorite within a hydrofractured veinBack to article page
