The Cadomian orogeny was first defined over 60 years ago to describe the earth movements which resulted in an unconformity between an Upper Proterozoic supracrustal sequence, namely the Brioverian, and Cambrian molasse The Cadomian orogeny book the north Armorican region.

Since that time the terminology has been extended to encompass an extensive orogenic cycle lasting from approximately - Ma recorded in a.

Guerrot & J.J. Peucat --The geology of the Penthièvre crystalline massif: a reappraisal of the type-Pentevrian area. The Cadomian Orogeny comprises a series of complex sedimentary, magmatic and tectonometamorphic events that spanned the period from the mid-Neoproterozoic (c.

Ma) to the earliest Cambrian (c. Ma) along the periphery of the super-continent Gondwana (peri-Gondwana, Fig.

).Modern data demonstrate broad continuity between Cadomian events and the later opening of the Rheic Ocean. The Saamian orogeny is one of the earliest recognizable events in the formation of the Baltic Shield, between and billion years ago in the Archean and Proterozoic.

The Saamian orogeny is associated with intense plutonic activity that intruded massive granitoid deposits. The event lined up with the Katarchean, a period in which the Earth's crust approached its present thickness and. Originally about km long, the belt is made up of a number of terranes later separated by the Caledonian orogeny (c.

Ma), Variscan orogeny (c. Ma), and the recent opening ofthe Atlantic Ocean (c. 70 Ma). The rocks therefore are now located on both sides of the Atlantic, as far apart as Florida and : Paperback.

The Scandian orogeny was an orogeny mountain building event, preserved in the rocks of eastern Greenland, eastern Svalbard, northern Scotland and much of the coast of Norway.

The orogeny occurred from to million years ago, as Baltica and Laurentia collided. The remnants of an ophiolite complex which was obducted eastward onto Baltica are located on southwest coast of ic regions: Orogens, Acadian, Alpine.

Granitoid plutonism at to Ma documents the final pulse of the Cadomian Orogeny. Hf isotope compositions, calculated ɛHfi values and TDM model ages for detrital and magmatic zircon show that during the c. Ma long Cadomian magmatic arc activity juvenile arc magmas were contaminated by recycling of Eburnian and Archaean crust.

Avalonian and Cadomian Geology of the North Atlantic aims to provide region by region syntheses of those terranes which are believed to have once formed part of the Late Proterozoic Avalonian-Cadomian belt.

The belt originally comprised a series of volcanic arcs and marginal basins formed during the period c. Ma ago, producing a range of calc-alkaline volcanics and intrusives and. The timing coincided with a range of global orogenies, e.g., the Pan-African orogeny (ca.

Ma, Kröner and Stern, ), and the Cadomian orogeny ( Ma, Linnemann et al., Folding and anchimetamorphism of the Lausitz Group reflect compressional processes during the Cadomian orogeny.

Although the closure of an ocean cannot be assumed (Nance and Murphy, ), the geochemical signatures of intercalated basic rocks (type II in Fig. 11) indicate that considerable quantities of oceanic crust were subducted.

Review of existing plate tectonic theories of the Lower Palaeozoic development of the north and northwest British Isles leads to the conclusion that ridge-trench impingement theory can be used to integrate all known geological observations within one unified plate tectonic theory for the area.

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. and Eurasian plates over the last Ma of Earth’s history.

The papers in this volume present overviews of the Cadomian evolution, the post-Cadomian development of the passive margin, a state of the art assessment of the biostratigraphic record of Saxo-Thuringian sediments, various aspects of the Variscan reworking of the Saxo-Thuringian Zone and processes related to the erosion of the Variscan Orogen.

Abstract. Two Gondwana-derived Paleozoic belts rim the Archean/Paleoproterozoic nucleus of the East European Platform in the Black Sea region. In the north is a belt of Paleozoic passive-margin-type sedimentary rocks, which extends from Moesia to the Istanbul Zone and to parts of the Scythian Platform (the MOIS Block).Cited by: Sark (French: Sercq; Sercquiais: Sèr or Cerq) is a part of the Channel Islands in the southwestern English Channel, off the coast of Normandy, is a royal fief, which forms part of the Bailiwick of Guernsey, with its own set of laws based on Norman law and its own parliament.

One of the structural features left following the Pan-African orogeny was an elongate arch extending SE–NW from the Tibisti Mountains to the vicinity of Tripoli, and evidence of this arch is to be found in the separation of the Kufrah and Murzuq basins, in the Brak-Bin Ghanimah Uplift.
