Figure F102. Brecciation, alteration, and quartz-pyrite veining of completely altered volcanic rock. Note that alteration associated with the veining overprints earlier alteration of many of the fragments and that several of the fragments fit together (jigsaw-fit breccia) (cf. Fig. F100, ) (Unit 9; interval 193-1189A-5R-1, 42-50 cm).
