| 31. | In the region, mafic volcanism has been active since the Oligocene.
|
| 32. | Most volcanism in the area is of silicic nature however.
|
| 33. | Later tectonic changes caused a start of more alkaline volcanism.
|
| 34. | The separation and assembly of plates induced the Karoo volcanism intrusive event.
|
| 35. | Volcanism in the field may be influenced by faults in the area.
|
| 36. | Such volcanoes can constitute a threat to regions with seemingly quiet volcanism.
|
| 37. | Strong volcanism and uplifting occurred between 15and 20million years ago.
|
| 38. | After volcanism ended, lacustrine deposition occurred in the area.
|
| 39. | Volcanism appears to be associated with crustal extension at Erciyes.
|
| 40. | The noises suggested seismic activity, even volcanism, far under the ice.
