New constraints on the timing of the late Carboniferous - early Permian volcanism in the central North Sea. Neumann, E. Carboniferous-Permian rifting and magmatism in southern Scandinavia, the North Sea and northern Germany: a review. Pracht, M. Terra Nova 13, Balagansky V.
Geology links Boggy. Home Contact. There can hardly be a more researched system in the whole of the British Isles, given its widespread distribution at outcrop and annual appearances in numerous PhD theses including those of the authors. But perhaps all we really know about the Carboniferous is no more than skimming the surface. In this atlas, using modern multifold seismic and borehole data collected by the oil industry in its search for petroleum accumulations, we can start to look beyond the surface exposures and gain some new insights into the structure and stratigraphy of the subsurface and surface Carboniferous.
Saar—Nahe Basin is a molasse basin in southwest Germany. The aggregation of sediments in the basin started in the late Carboniferous and Early Permian as part of the Variscan orogeny.

Mainly acidic Stephanian to early Permian volcanic rocks and intercalated sediments accumulated in the Thuringian Forest Basin TFB in central Germany to a total thickness of ca. This basin offers a wide range of biostratigraphic information. Pre-treatment of the zircons by chemical abrasion was important to get rid of severe Pb loss. The zircon ages of the investigated formations indicate that the total duration of the volcanic activity in the TFB was considerably shorter [ca. Consequently, the well-documented gap of the sedimentary record from the early Permian volcanic rocks up to the Illawarra geomagnetic reversal has to be extended to ca. The zircon ages of the investigated volcanic rocks allow the constraining of some intercalated fossiliferous horizons crucial for biostratigraphic correlation of latest Carboniferous—early Permian Rotliegend sections.

Upton, B. In: Wilson, M. Permo-Carboniferous magmatism and rifting in Europe. 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. In Scotland Dinantian magmatism was dominantly mildly alkaline-transitional in composition. Tournaisian activity was followed by widespread Visean eruptions largely concentrated within the Scottish Midland Valley where the lava successions, dominantly of basaltic-hawaiitic composition, attained thicknesses of up to m. Changing stress fields in the late Visean coincided with a change in the nature of the igneous activity; subsequently, wholly basic magmatism persisted into the Silesian.
Whilst most of the Carboniferous-Permian rift basins of NW Europe developed on relatively thin lithosphere, the highly magmatic Oslo Graben.

In order to discuss the development of the Oslo Graben in terms of plate vs. The most important of these events is the emplacement of a suite of alkaline and tholeiitic basalts at ca. Except for this basaltic spike, all the areas show different tectonomagmatic developments.
