Interpretation
1 Massive with some subtle gradations in grain size; includes thin layers of very coarse sand to granules Very fine sand to pebble Very poor 20 cm to >10 m Lithic vitric lapilli tuff Muddy debris flow deposit
2 Massive, grain size oscillations Coarse sand to pebble Very poor 2-30 m Lithic vitric lapilli tuff to lapillistone Stony debris flow deposit
3 Inclined granule lamination Medium sand to granule Poor 2-5 m Lithic vitric lapilli tuff Current-reworked deposit
4 Grading, parallel lamination, traction carpet Fine to very coarse sand Moderate 5-200 cm Lithic vitric tuff Turbidite
5 Massive, clast supported Granule to pebble Moderate 20 cm to 10 m Tachylitic lapillistone Quenched subaerial eruptive products
6 Chaotic bedding Fine sand to pebble Very poor >3 m Lithic vitric lapilli tuff Slump deposit
7 Inverse grading, mud drape Clay, very fine to coarse sand Good ~20 cm Lithic vitric tuff and mudstone Fluvial deposit?
8 Massive Silt to very fine sand Good 5 cm Lithic vitric tuff Air-fall ash
