| 21. | In the present day, volcanism is of andesitic composition forming volcanic cones.
|
| 22. | Volcanic activity has generated first dacitic lava flows and subsequently andesitic lava flows.
|
| 23. | The former two are andesitic, while the latter is a pyroclastic cone.
|
| 24. | The andesitic lavas contain phenocrysts of andesine, hornblende, plagioclase and hypersthene.
|
| 25. | These preceding centres have left andesitic lava flows that are partially dissected and agglomerates.
|
| 26. | It is located near both Tomakomai and andesitic stratovolcano, with a lava dome.
|
| 27. | The volcano developed during the Pleistocene of andesitic-to-dacitic lava flows.
|
| 28. | The initial activity was andesitic, but later became rhyolytic ( 12 Ma ).
|
| 29. | The volcanism is at first andesitic and later becomes intermediary between andesite and basalt.
|
| 30. | The most recent volcanic phase began about 4 mya, producing largely andesitic eruptions.
