Figure F13. Angular, blocky to platy, vesicular and nonvesicular volcanic clasts are densely packed, forming a clast-supported fabric in sulfide-poor domains of Unit 21. This indicates that the unit is a volcaniclastic breccia. Arrow = the variable orientation of the clasts. (Sample 193-1189A-12R-1 [Piece 16, 122-126 cm]; width of view = 5.5 mm.
