The northern Namibian Karoo-aged successions are part of a Gondwana-wide sedimentary system emerging at the Carboniferous–Permian boundary and existing for more than 50 Ma. Karoo Supergroup importance in understanding evolution rift system. This study presents new whole-rock geochemical data combined with detrital zircon morphology as well U−Pb ages Lu−Hf composition late Palaeozoic siliciclast...

Впервые приводится характеристика водорослевого сообщества из нижнепермских (приуральских) отложений шихана Куштау. Водоросли изучены по шлифам образцов скважины, пробуренной в седловине шихана, вскрывшей ассельский и сакмарский ярусы. В отложениях Стерлитамакских шиханов наиболее многочисленны тубифитесы, условно относимые к семейству сине-зелёных водорослей Girvanellaceae. Тубифитесы известны...

In the northern Iberian Peninsula, Pyrenean-Cantabrian orogenic belt extends E-W for ca. 1000 km between Atlantic Ocean and Mediterranean Sea. This orogen developed from collision Iberia Eurasia, mainly in Cenozoic times. Lower-middle Permian sediments crop out small, elongated basins traditionally considered independent each other due to misinterpretations on incomplete lithostratigraphic data...

Large volumes of carbonate breccia occur in the late syn-rift and early post-rift deposits of the Billefjorden Trough, Central Spitsbergen. Breccias are developed throughout the Moscovian Minkinfjellet Formation and in basal parts of the Kazimovian Wordiekammen Formation. Breccias can be divided into two categories: (i) thick, cross-cutting breccia-bodies up to 200 m thick that are associated w...

Developed on the North China Craton, intracratonic Ordos Basin contains a complete Paleozoic-to-Cenozoic sediment record, allowing for long-term paleoenvironmental and climate change investigation. During Carboniferous–Permian period, convergence between block paleo-Yangtze plate to south resulted in general marine regression characterized by series of second-order transgression/regression cycl...
