The northern part of the shield is truncated by a 10 km wide embayment, open to the north and filled by postshield volcanism. |
The radiometric age data combined with the petrography of the volcanics thus indicate two separate events of volcanism in the Danish North Sea. |
The late Aalenian until the end of the Bathonian was characterized by basaltic volcanism. |
Geologically young, the Rockies exhibit faulting, glaciation, and volcanism, resulting in rugged, spectacularly scenic terrain. |
This volcanism seemingly developed in an extensional setting near a shelf margin located in the eastern Neptune Range. |
This appears to contradict evidence from other areas, particularly Wales where subduction-related volcanism occurs in the late Tremadoc. |
