Late Ediacaran opening of the Iapetus Ocean is typically considered to reflect separation Baltica and Laurentia during final breakup Rodinia supercontinent, with subsequent closure Caledonian Orogeny. However, evidence pre-opening juxtaposition limited purportedly similar apparent polar wander paths correlation Rodinia-forming orogenic events. We show that a range existing data do not unequivoc...

The İstanbul-Zonguldak Tectonic Unit is regarded as the easternmost fragment of Avalonia-Carolina and stands for Far East Avalonia. Its stratigraphy also characterized by discontinuous sedimentation from Late Ediacaran to Carboniferous. In western part block, known İstanbul Terrane, Gözdağ Formation represented lagoonal sedimentary rocks consisting shale-sandstone with limestone Middle Ordovici...

The sources of the Paleocene London Basin marine to fluviodeltaic sandstones are currently unclear. High analysis number detrital zircon U-Pb age investigation an early-mid Thanetian sand from East Kent, reveals a large spread peaks indicative range primary sources. In particular, strong Ediacaran peak is associated with Cadomian Orogeny, while secondary represent Caledonian and various Mesopro...

Abstract. In Europe, formation of the Palaeozoic Variscan orogenic belt, and Mesozoic–Cenozoic Alpine–Carpathian belt led to a widespread inversion events within forelands both domains. We used legacy 2-D seismic data together with newly acquired 3-D that, for first time, precisely imaged sub-Zechstein (i.e. sub-evaporitic) upper successions in NW Poland order develop quantitative, balanced mod...

The Caledonian orogenic belt of northern Britain hosts some significant quartz vein-hosted gold deposits. However, as in orogenic belts worldwide, the relationship between gold mineralization and regional tectonics, magmatism, and metamorphism is a matter of debate. This is primarily due to the absence of precise temporal constraints for the mineralization. Here we report high-precision 40Ar/39...

The Billefjorden Fault Zone is a major terrane boundary in the Norwegian Arctic. fault separates basement rocks of Svalbard’s north-eastern and north-western terranes that recorded discrete Precambrian tectonothermal histories were accreted, intensely deformed metamorphosed during Caledonian Orogeny. Although represents major, crustal-scale tectonic boundary, its northward extent not well const...

The Lindås Nappe, Bergen Arc, is located in western Norway and displays two high-grade metamorphic structures. A Precambrian granulite facies foliation is transected by Caledonian fluid-induced eclogite-facies shear zones and pseudotachylytes. To understand how a superimposed tectonic event may influence olivine fabric and change seismic anisotropy, two lenses of spinel lherzolite were studied ...
