| 21. | The lava flows are layered, separated by a thin layer of lapilli tuff and reddened breccia.
|
| 22. | The summit is formed from the tuff, lapilli-tuff and breccia of the Lingmell Formation.
|
| 23. | The cone shaped deposits are fairly uniform and consist primarily of tuff in lapilli-size particles.
|
| 24. | These scoria cones are formed by lapilli and pyroclastics with no welding and also contain lava bombs.
|
| 25. | Several small shield volcanoes, and postglacial lapilli cones and lava flows have been reported in this area.
|
| 26. | Between the individual lava flows may be beds of lapilli-tuff resulting from a more explosive eruption.
|
| 27. | The white matrix found between lapilli contains alkalifeldspath, hematite, hisingerite, montmorillonite, saponite and silica.
|
| 28. | The Big Scott Mountain formation consists of rhyolite of variable composition, lapilli-tuff, and crystal tuff.
|
| 29. | This is followed by fallout of accretionary lapilli, which is the result of particle agglomeration within the column.
|
| 30. | The immediate area was completely buried by thick layers of pyroclastic fragments, volcanic blocks, lapilli and ash.
