| Rejuvenescent volcanism occurs on many oceanic islands, including the Society Islands. |
| This appears to contradict evidence from other areas, particularly Wales where subduction-related volcanism occurs in the late Tremadoc. |
| This volcanism seemingly developed in an extensional setting near a shelf margin located in the eastern Neptune Range. |
| An active origin is suggested because volcanism and uplift appear to have preceded rifting, an active plume passing over a large area. |
| The northern part of the shield is truncated by a 10 km wide embayment, open to the north and filled by postshield volcanism. |
| Influx of trachytic volcanic rock fragments in the Albian may derive from inlra-platc volcanism related to extension. |
