Occurrences of the pseudotachylyte-bearing dark veins in the Shimanto accretionary complex. (a) Dark veins (red arrows) sharply bounding the foliated cataclasite. (b) Enlarged view of the dark vein (red arrow). (c) Dark and injection veins under plane-polarized light. (d) The pseudotachylyte surviving alteration, which is recognized as the transparent material under plane-polarized light (red arrow). The red double arrow indicates the dark vein.
