| 1. | Kari-Kari has erupted welded tuffs that contain garnet.
|
| 2. | Refer to geology, white sandbar is on the base of welded tuff.
|
| 3. | Igneous rocks can become foliated by alignment of welded tuff and pyroclastic surge deposits.
|
| 4. | It is a dacitic welded tuff with a high crystal and moderate pumice content.
|
| 5. | Welded tuff is commonly rhyolitic in composition, but examples of all compositions are known.
|
| 6. | They comprise dikes, welded tuffs, pitchstones, volcanic plugs, laccoliths and flows.
|
| 7. | These crystal rich welded tuffs accumulated within the caldera and have a volume of about.
|
| 8. | Most of the complex is covered by the Miocene welded tuffs of Llano Las Vicu�as ignimbrites.
|
| 9. | Each eruption involved pyroclastic flows and produced some of the welded tuff now found west of the Rio Grande.
|
| 10. | Commonly in most felsic ignimbrites the quartz polymorphs cristobalite and tridymite are usually found within the welded tuffs and breccias.
