caledonian orogeny उदाहरण वाक्य
उदाहरण वाक्य
- Plate convergence that caused the Caledonian orogeny in the Silurian continued to form the Variscan orogeny in the succeeding Devonian and Carboniferous Periods.
- The formation of these has been influenced by the zig zag suture line of the Caledonian orogeny with its areas of crustal tension weakness.
- On the other hand, the early Paleozoic rocks were deformed and metamorphosed to a higher degree during the Caledonian orogeny ( about ).
- The sediments of the Arverne domain were metamorphosed mainly during the Acadian phase of the Caledonian orogeny about 400 350 million years ago.
- This event is the Caledonian orogeny, a spate of mountain building that stretched from New York State through conjoined Europe and Greenland to Norway.
- The continents Laurentia and Baltica collided between 450 and 400 Ma, during the Caledonian Orogeny, to form Laurussia ( also known as Euramerica ).
- Even earlier orogenies relevant for the ultimate formation of Europe are the Caledonian orogeny, some 400 Mya and the Variscan orogeny, some 300 Mya.
- Seafloor spreading to the south of Avalonia pushed the latter into north Laurentia and thrust up the northern Appalachian Mountains in the acadian phase of the Caledonian orogeny.
- In common with the Devonian basins of Norway and East Greenland, the Orcadian Basin lies entirely within the area affected by crustal thickening during the Caledonian orogeny.
- The included volcanic rocks and the conglomerates hint at unsettled tectonic conditions, which are probably connected with an early stage of the Caledonian orogeny ( Taconian Phase ).
