The term Mediterranean-Mjosa Zone (Mittelmeer-Mjösen-Zone) was coined by the German geologist Hans Stille in about 1930 to describe a rift in the continental Crust crossing Europe from the Mediterranean Sea via Marseille, the Rhine rift as far as Mjøsa in the south of Norway, a total length of 2000 km.
The axis of the rift area may contain volcanic rocks, and active volcanism is a part of many, but not all, active rift systems. Major rifts occur along the central axis of most mid-ocean ridges , where new oceanic crust and lithosphere is created along a divergent boundary between two tectonic plates .
The Aegean Sea plate (also called the Hellenic plate or Aegean plate) is a small tectonic plate located in the Eastern Mediterranean under Southern Greece and western Turkey. Its southern edge is the Hellenic subduction zone south of Crete , where the African plate is being swept under the Aegean Sea plate. [ 1 ]
Most important structures and zones of the Hercynian orogeny in Europe. [1] The Iberian plate is a microplate typically grouped with the Eurasian plate that includes the microcontinent Iberia, Corsica, Sardinia, the Balearic Islands, the Briançonnais zone of the Penninic nappes of the Alps, and the portion of Morocco north of the High Atlas ...
Continental fragments and microcontinent crustal compositions are very similar to those of regular continental crust.The rifting process that caused the continental fragments to form most likely impacts their layers and overall thickness along with the addition of mafic intrusions to the crust.
The White Sea Rift System is a complex of rifts manifested as numerous individual grabens located chiefly in the White Sea but including onshore areas and a strip of the Barents Sea. The rifts run in a subparallel manner from northwest to southeast where the rift system continues under the East European Platform .
Spain’s marine rescue service reported Friday it had intercepted another 500 migrants in six boats approaching the Canary Islands, located off the northwestern coast of Africa.
Silfra fissure The Mid-Atlantic Ridge passing through Þingvellir Rocks and boulders that have piled up in the fissure due to earthquakes.. Silfra (Icelandic pronunciation: [ˈsɪl(v)ra]) is a rift formed in the Mid-Atlantic Ridge – the divergent tectonic boundary between the North American and Eurasian plates – and is located in the Þingvallavatn Lake in the Þingvellir National Park in ...
