Figure F74. Brittle structures. A. Dense anastomosing fracturing (Rank 3; Sample 345-U1415J-21R-1, 0–13 cm [Piece 1]). B. Well-developed brecciation (Rank 4; Sample 345-U1415J-21R-1, 113–124 cm [Piece 16]). C. Cataclasite (Rank 5) with strong cataclastic foliation (Sample 345-U1415J-21R-1, 16–23 cm [Piece 4]). D. Fine-grained prehnite vein (center) and chlorite vein (right) developed along subvertical-oriented cataclasite zone (Thin Section 79; Sample 345-U1415J-21R-1, 103–107 cm [Piece 14]). E. Cataclasite (Thin Section 77; Sample 345-U1415J-21R-1, 17–19 cm [Piece 4]). F. Crosscutting relationship between cataclasite zone and chlorite vein (also Thin Section 77). G. Chlorite filled space in fractured plagioclase (Thin Section 80; Sample 345-U1415J-21R-1, 118–121 cm [Piece 16]). D–G are under crossed polars.
