| Text Description: | Kaguyak Ignimbrite. thick indurated but not sintered ignimbrite includes several 2-3-m-thick LCZ's and one very thick (20.3 m) LCZ near top of ignimbrite ~2m ignimbrite overlies thick LCZ. Ignimbrite overlies what is probably the Big Breccia deposit. Exposed thickness 45-50 m. PCZ's; LCZ: 2 to 20 m. See text for MP and ML. Pumice clasts: pumices generally pale grey, with fewer dark blebs than most pumices at other locations. Lithic clasts: most lithics are andesite-dacite lavas; a minor subset have yellow-orange alteration rinds or films; basal 3-m of the thick LCZ includes ~30% yellow orange altered crystal-poor lava clasts with pyrite; this is the only LCZ zone seen |
