DEVONIAN-CARBONIFEROUS MAGMATISM AND METALLOGENY IN THE SOUTH URAL ACCRETIONARY-COLLISIONAL SYSTEM
Геодинамика и тектонофизика, 2021 The oceanic stage in the history of the South Urals completed in the Ordovician – Early Silurian. The Ordovician through Devonian events in the region included the formation of an island arc in the East Ural zone from the Middle Ordovician to Silurian ...

Nature and timing of Late Mississippian to Mid-Pennsylvanian glacio-eustatic sea-level changes of the Pennine Basin, UK [PDF]
, 2012 The Pennine Basin of northern England contains a comparatively complete Serpukhovian– Moscovian succession characterized by high-resolution ammonoid zonation and cyclic paralic sedimentation.

Early Carboniferous radiolarians from north‐west Thailand: palaeogeographical implications [PDF]
Palaeontology, 2004 Moderately well‐preserved radiolarian assemblages are described from bedded cherts south of Mae Hong Son, north‐west Thailand. Twenty species and subspecies are identified, including one new species (Archocyrtium sashidai Feng sp. nov.). The assemblages belong to the middle Early Carboniferous Albaillella indensis and Eostylodictya rota zones.

Royal Society Open Science, 2021 Evidence for terrestriality in early tetrapods is fundamentally contradictory. Fossil trackways attributed to early terrestrial tetrapods long predate the first body fossils from the Late Devonian.

Early Carboniferous extension in East Avalonia: 350 My record of lithospheric memory [PDF]
Marine and Petroleum Geology, 2018 Despite reactivations during Variscan and Alpine orogenies and the opening of the Northern Atlantic, Avalonia is one of the few regions where the initial Mid-Paleozoic basin structure is still recognisable, largely intact, and well studied. Its kinematics and dynamics remain, however, largely unknown, in particular in view of the successive late ...

The Carboniferous Southern Pennine Basin, UK [PDF]
, 2014 Many of the Carboniferous outcrops located in the Derbyshire region of the Peak District National Park, UK, have provided sites for both significant and pioneering research relating to the clastic sedimentology of marine palaeoenvironments, particularly ...

Rivista Italiana di Paleontologia e Stratigrafia, 2004 A new stratigraphic unit, the Tabai Limestone of the poorly known Tirah area of northwest Pakistan, is one of several Early Carboniferous carbonate units distributed along the North Gondwana margin, some connected with transgressive interludes. The Tabai

Carboniferous and Permian magmatism in Scotland [PDF]
, 2004 Extensional tectonics to the north of the Variscan Front during the Early Carboniferous generated fault-controlled basins across the British Isles, with accompanying basaltic magmatism.
