Figure F68. Unit 35 is a polymict volcaniclastic breccia with flow-banded clasts, dark green porous clasts, perlitic clasts, and textureless bleached clasts cemented in a quartz-hematite-sulfide matrix. Folded flow banding in one clast is truncated at the hinge of the fold, clearly indicating that the clast was abraded during transport. Fine sulfide veins in the clasts are terminated at the boundary of fragments, indicating that the formation of these veins predates erosion and deposition of the clasts (interval 193-1189B-18R-2, 49-58 cm).
