| 31. | In outcrops, lapilli tuff beds have also been identified in close association with the diamictite of the Squantum Member.
|
| 32. | The lower part of the formation consists of unwelded and highly compacted lapilli tuff with abundant amounts of pumice fragments.
|
| 33. | Tephra fall bed, lapilli, and surge deposits are also found, and the flow deposits contain pumice blocks.
|
| 34. | The NAKP volcanics, including the ML pipes, contain abundant lapilli and olivine supported in a fine-grained groundmass.
|
| 35. | The avalanche deposit consists mostly of loose material like ash, lapilli, pumice, and only a few lithic blocks.
|
| 36. | These rocks are quite indurated and tough, as opposed to non-welded lapilli tuffs, which are unconsolidated and easily eroded.
|
| 37. | Typically the sagitta is used, as it is largest, but sometimes lapilli are used if they have a more convenient shape.
|
| 38. | Grey pumice and scoria were deposited by this eruption, which was preceded by ash fall and ended with the deposition of lapilli.
|
| 39. | The lower member consists mainly of unwelded ( unjoined ), but heavily compacted, pumiceous lapilli-tuff and crystal tuff strata.
|
| 40. | A pumice-ridden lapilli-tuff section near the believed top section additionally has a 1 % composition of the mineral amphibole.
