North German basin : ウィキペディア英語版 | North German basin
The North German Basin is a passive-active rift basin located in central and west Europe, lying within the southeastern most portions of the North Sea and the southwestern Baltic Sea and across terrestrial portions of northern Germany, Netherlands, and Poland. The North German Basin is a sub-basin of the Southern Permian Basin, that accounts for a composite of intra-continental basins composed of Permian to Cenozoic sediments, which have accumulated to thicknesses around 10–12 km.〔 The complex evolution of the basin takes place from the Permian to the Cenozoic, and is largely influenced by multiple stages of rifting, subsidence, and salt tectonic events. The North German Basin also accounts for a significant amount of Western Europe's natural gas resources, including one of the worlds largest natural gas reservoir, the Groningen gas field.〔 ==Regional tectonic evolution==
The regional tectonic evolution of the North German Basin coincides with of the evolution of the Southern Permian Basin, the basin across central and western Europe. From the late Neoproterozoic Era to Carboniferous Period, Europe underwent the Caledonian Orogeny and Variscan Orogeny. These crustal accretion events produced the present day regional lithosphere, and by the time of the post-orogenic collapse of the Variscan Orogeny the supercontinent Pangea had completely formed.〔 After the formation of Pangea, much of the region underwent crustal instability and thus developing the extensive Permo-Carboniferous magmatic province.〔 This magmatism led to the extrusion of abundant volcanic successions such as the Northeast German Basin, Northwest Polish Basin, and Oslo Rift, while also causing the formation of 70 rift basins throughout the Permian Basin.〔 The regions most evolved and voluminous magmatism occurred within the North German Basin dating back to 297-302 Ma.
