| One of the initial consequences of the shrinking of Iapetus was a gradual decline in the provinciality of fossils. |
|
| It is composited of three views captured through ultraviolet, green, and infrared filters to bring out compositional variations across the sunlit hemisphere of Iapetus. |
|
| The splitting also created two new oceans, the Iapetus Ocean and Paleoasian Ocean. |
|
| It was caused by the closure of the Iapetus Ocean when the continents and terranes of Laurentia, Baltica and Avalonia collided. |
|
| These are interpreted as evidence that by that time, rifting had started that would form the Iapetus Ocean. |
|
| During the Permian and Triassic periods, with the Iapetus Ocean entirely closed, Scotland lay near the centre of the Pangaean supercontinent. |
|
| In the process, the Iapetus Ocean between Gondwana, Baltica and Laurentia closed. |
|
| At the time of their deposition, one tectonic plate was being subducted beneath another at the closure of the Iapetus Ocean. |
|
| Neither spherical nor ellipsoidal, as most moons are, Iapetus looks like a walnut, with a bulging waistline and squashed poles. |
|
| In Newfoundland and Labrador, the Long Range dikes are also thought to have formed during the formation of the Iapetus Ocean. |
|
| The Iapetus Ocean was situated in the southern hemisphere, between the paleocontinents of Laurentia, Baltica and Avalonia. |
|
| They were separated by an ocean, called the Iapetus Ocean by geologists. |
|
| This volcanic arc was formed above a subduction zone where the oceanic lithosphere of the Iapetus Ocean subducted southward under other oceanic lithosphere. |
|
| Across the Iapetus ocean to the south, was the continent of Baltica. |
|
| The most distinctive feature is the ultrabasic ophiolite, peridotite and gabbro on Unst and Fetlar, which are remnants of the Iapetus Ocean floor. |
|
| The Iapetus Ocean first closed in the north, then in the south. |
|
| The Iapetus Ocean was therefore named for the titan Iapetus, who in Greek mythology was the father of Atlas, after whom the Atlantic Ocean was named. |
|
| These are essentially the remains of folded sedimentary rocks that were deposited between 1,000 Ma and 670 Ma over the gneiss on what was then the floor of the Iapetus Ocean. |
|
| Atlas was the son of the Titan Iapetus and the Oceanid Asia or Clymene. |
|
| The first twelve Titans comprised the females Mnemosyne, Tethys, Theia, Phoebe, Rhea, and Themis and the males Oceanus, Hyperion, Coeus, Cronus, Crius, and Iapetus. |
|
|
|
| Baltica, Laurentia, and Avalonia all came together by the end of the Ordovician to form a minor supercontinent called Euramerica or Laurussia, closing the Iapetus Ocean. |
|
| Avalonia had not yet collided with Laurentia, but as Avalonia inched towards Laurentia, the seaway between them, a remnant of the Iapetus Ocean, was slowly shrinking. |
|
| The Iapetus Suture runs through the north and west of the state, being underlain by the ancient Laurentian terrane, and the south and east underlain by the Avalonian terrane. |
