Table 2. Volcaniclastic facies in Unit II at Site 1184.
Facies | Sedimentary structure | Grain size | Sorting | Thickness | Lithology | 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 to10 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 |
