[…] Figure 9: Sketch of an exposed fault surface coated with thin sheets of overlapping tension veins. The leading edges of the veins (T surfaces) form a series of asymmetric steps which face towards the direction of movement of the missing fault block. Within the veins, minerals have grown in the direction of extension (i.e. at right angles to the T surfaces) typically defining a strong lineation in the direction of shear. These are known as “fibres”. For a photograph of this structure see Part 2 (E) […]
