The Rheic Ocean was an ocean which separated two major palaeocontinents, Gondwana and Laurussia (Laurentia-Baltica-Avalonia).One of the principal oceans of the Palaeozoic, its sutures today stre km (6, mi) from Mexico to Turkey and its closure resulted in the assembly of the supercontinent Pangaea and the formation of the Variscan–Alleghenian–Ouachita orogenies.

The evolution of the Rheic Ocean is consequently central not only to the history of the Palaeozoic, but also to the broader issue of supercontinent assembly (e.g., Murphy et al.,Santosh et al., ).

Highlights The Rheic Ocean separated Gondwana and Laurussia as the principal interior ocean of the Paleozoic. Its evolution dominates the geology of southern The Evolution of the Rheic Ocean book, eastern North America and northern Africa following the closure of the Iapetus Ocean in the Silurian.

Closure of the Rheic Ocean in the late Paleozoic created the vast Ouachita-Appalachian-Variscan orogen and assembled. The Rheic Ocean is the most significant Paleozoic ocean that detached peri-Gondwana terranes from the northern Gondwana margin throughout the closure of the Iapetus Ocean. The suture of the Rheic Ocean spreads from Mexico to the Middle East, and the timing of its final closure is well-documented by the rocks formed in the Variscan-Alleghanian.

We conducted an integrated study based on sedimentology. Other articles where Rheic Ocean is discussed: Silurian Period: Gondwana: Europe (Baltica) is called the Rheic Ocean and was essentially a southwestern extension of the Paleotethys Sea. The flooded margin of eastern Australia had a more-varied seafloor topography than the other shallow seas because of the extensive volcanism occurring there during Silurian time, but it shared many of the.

Granite emplacement and sediment deposition can be related to the separation of the Avalonia microterrane from the northern Gondwana margin. Amphibolite protoliths of the Randamphibolit-Serie emplaced at c. They show N-MORB to E-MORB signatures, pointing to their formation along an oceanic spreading centre within the Rheic ocean.

Palaeozoic evolution. The ocean formed when Pannotia disintegrated, Proto-Laurasia (Laurentia, Baltica, and Siberia) rifted away from a supercontinent that would become Gondwana.

Proto-Tethys formed between these two supercontinents. The ocean was bordered by Panthalassic Ocean to the north, separating it from Panthalassa by island arcs and. is a platform for academics to share research papers.

Its suture extends from Mexico to Turkey and its closure produced the climactic Variscan–Alleghanian–Ouachita orogeny that assembled the supercontinent, Pangaea.

LA-MC-ICP-MS U-Pb zircon ages and whole-rock geochemical data obtained from volcanic rocks erupted in the northern margin of Gondwana provide new insights on the polyphase magmatic evolution of the NW Iberian domain during the establishment of passive margin conditions in Lower Paleozoic times.

The book provides an updated review of the geology of Iberia and its continental margins from a geodynamic perspective and discusses how Iberia played a pivotal role in the geodynamic evolution of the Gondwanan, Rheic, Pangea, Tethys s.l.

Adopting a global approach, this unique book provides an updated review of the geology of Iberia and its continental margins from a geodynamic perspective. Owing to its location close to successive plate margins, Iberia has played a pivotal role in the geodynamic evolution of the Gondwanan, Rheic, Pangea, Tethys and Eurasian plates over the.

If there is evidence for an old ocean, then this could be used to support the evolutionist's supposition that life arose from primitive, inorganic marine chemicals over a billion years ago. If, however, the world ocean can be shown to be a relatively youthful feature, then the evolutionist.
