| 11. | Historical maars and silicic lava domes are found along the Great Sumatran Fault line.
|
| 12. | Characteristics can be sorted to infer subaqueous eruption or emplacement of silicic pyroclastic deposits.
|
| 13. | Andesitic enclaves are also present and some dacites border on silicic andesite in composition.
|
| 14. | The presence of silicic volcanic rocks such as rhyolite is also indicative of explosive eruptions.
|
| 15. | Records of silicic eruptions begin with remnants from the Barroso formation, from the Miocene.
|
| 16. | A 7 km?silicic lava flow lies on the saddle between the volcano and Acamarachi.
|
| 17. | It is thought that fossils were pervaded with silicic acid due to this volcanic activity.
|
| 18. | The mountains are remnants of ancient silicic volcanoes that have been worn down by erosion.
|
| 19. | When this silicic lava emerges at the surface, it's highly gas-charged.
