Table T1. Classification for consolidated volcaniclastic rock. (See table notes.)
| Grain size (mm) | Nongenetic nomenclature | Genetic nomenclature |
|---|---|---|
| <1/16 | Volcaniclastic mudstone | Fine hyaloclastite |
| 1/16–2 | Volcaniclastic sandstone | Hyaloclastite sandstone |
| 2–4 |
Volcaniclastic conglomerate/ Volcaniclastic breccia |
Granular hyaloclastite |
| 4–64 | Hyaloclastite breccia | |
| >64 |
Notes: Modified from Fisher (1961). Genetic nomenclature was used only for hyaloclastics at Site U1348.
