In 2002, the World Heritage Site designation was extended to include an expanded marine zone of 1,997 km². Cocos Island is an oceanic island of both volcanic and tectonic origin. It is the only emergent island of the Cocos Plate, one of the minor tectonic plates

Hadrian’s WallThe Whin Sill is a tabular layer of igneous rock, or sill, in thenortheast of England. The Romans certainly appreciated andexploited the geology. Emperor Hadrian chose the narrowestroute across northern England for his Wall, and took advantageof the natural defenses of the crags between Walltown andSewingshields. These crags mark the outcrop of the Whin Sill,one of the most important features of northern Englandgeology.

The Newfoundland StoryRocks on the Island of Newfoundland are divided into three zones -Western, Central and Eastern. The Western Zone has been part of NorthAmerica for at least the last billion years (1000 million), but the othertwo zones are relative newcomers.Geological Subdivisions of Newfoundland.The bringing together of ancient oceans and continents has givenNewfoundland three geological zones: the Western, Central and Easternzones. Each of these zones has distinct rock types and geologicalhistories.
Newfoundland preserves evidence of the closing of the Iapetus ocean,the collision of the continents and the resulting deformation.
Layered limestones and shales at Green Point, Gros Morne National Park.The rocks of the coastal terrace and cliffs at Green Point originated offshorein the Iapetus Ocean about 500 million years ago. These fossil-bearing limestonesand shales were transported from about 100 km to the east of this site duringthe collision of ancient continents. Now they lie tipped at 115 degrees, just past thevertical. This is one of the rock sequences that geologists have studies in theirattempt to reconstruct the ancient continental margin of eastern North America.
The Mohorovicic Discontinuity, which reflects the different densities of thecrust and the mantle, normally occurs at a depth of 35 km beneath thecontinents and about 10 km beneath the oceans. But here you can literallystand with one foot on the gabbro of the ocean crust and the other on theperidotite of the ocean mantle. It is because of this unusual sequence ofrocks and other aspects of Gros Mornes geology and landscape that in 1988Gros Morne was declared a UNESCO World Heritage Site..
