Analysis of the distribution of detrital zircon grains is one of the few parameters by which Precambrian palaeogeography may be interpreted. However, the break-up of Pangea and the subsequent dispersal of some of its fragments around the Indian Ocean demonstrate that zircon analysis alone may be misleading, since zircons indicate their original derivation and not their subsequent plate-tectonic pathways. Based on analysis of Precambrian–Ordovician zircon distributions, the presence of microconti...

Beranoaguirre et al. (Int J Earth Sci 108:2037–2046, 2019) have added a valuable piece of information to the Carboniferous tectono-thermal record of Europe by documenting a short-term pulse of heating in high-pressure metamorphic rocks of the NW-Iberian allochthons (c. 350 Ma, Malpica–Tui unit). They correctly state that the short duration of the thermal event is untypical of orogenic subduction/collision processes, but still envisage short-time heating within the subduction channel. The present...

Our paper reports the detrital zircon record from Late Devonian to late Carboniferous foreland basin deposits in the Rheno-Hercynian (RH) Variscides of Germany. Together with a review of petrograph...

Abstract Geological evidence, supported by biogeographical data and in accord with palaeomagnetic constraints, indicates that “one ocean” models for the Variscides should be discarded, and confirms, instead, the existence of three Gondwana-derived microcontinents which were involved in the Variscan collision: Avalonia, North Armorica (Franconia and Thuringia subdivided by a failed Vesser Rift), and South Armorica (Central Iberia/Armorica/Bohemia), all divided by small oceans. In addition, parts ...

Sedimentary petrography and zircon ICP-MS laser ablation ages from synorogenic clastic sediments in the Rheno-Hercynian Belt of Germany (Rheinisches Schiefergebirge, Harz) reveal basal tectonic accretion followed by exhumation and recycling of Baltica-derived Devonian shelf sediments. The recycled sediment volume demands a substantial palinspastic addition to the passive, northern margin of the Rheno-Hercynian basin. Detrital zircon ages from the Late Carboniferous foreland basin and their possi...

The Variscan orogenic collage consists of three subduction-collision systems (Rheno-Hercynian, Saxo-Thuringian and Massif Central-Moldanubian). Devonian to early Carboniferous marine strata are widespread not only in the individual foreland fold and thrust belts, but also in post-tectonic basins within these foreland belts and on the Cadomian crust of peri-Gondwanan microcontinental fragments, which represent the upper plates of the subduction/collision zones. These marine basins preclude high e...

The Horre Belt in the SE part of the Rhenish Massif has been regarded as autochthonous because of the apparent lack of metamorphic inversion. We have performed a K-white mica study using powder X-ray diffraction derived Kubler Index (KI) and K-white mica b cell dimension, and the spectrally derived wavelength of the 2,200 nm absorption feature (“2200wvl”) of supposedly allochthonous units and the underlying par-autochthon. KI reveals a slight, but significant inversion of metamorphic grade, whic...

The present comment disproves the tectonic model of a late Devonian/early Carboniferous Tibetan-style collisional plateau in the Tepla-Barrandean (TB) part of the Bohemian Massif, which later collapsed by thermal weakening of the underlying crust. Contrary to this model, the TB neither reveals major crustal thickening nor uplift and erosion, and eastern continuations of the TB were, during the relevant time-span, areas of open marine sedimentation. Late Devonian/early Carboniferous marine sedime...
