Germanic Basin

The Germanic Basin (German: Germanisches Becken) is a large region of sedimentation in Western and Central Europe that, during the Permian and Triassic periods, extended from England in the west to the eastern border of Poland in the east.

To the south it is bounded by the Vindelician Ridge (Vindelizische Schwelle) and, to the west and northwest, by the Armorican and London-Brabant Massifs. To the north the basin is bordered by the highlands of Ireland and Scotland, which were then still connected to the North American continent. To the east the basin was defined by the East European Platform, to the northeast by the Fennoscandinavian Shield (Scandinavia and Finland). The sedimentation began in the Rotliegendes with continental depositions. Later, during the Zechstein and Muschelkalk the region was largely flooded by the sea. Bunter sandstone and Keuper are again largely of continental origin. But even in these rocks the perimeter regions have marine influences, short incursions of the sea also reached the centre of the basin in northern Germany.

During the Zechstein the sea ingressed from the Arctic Ocean to the north into the basin. This gateway closed during the Uppermost Permian. In the Triassic these marine incursions came through several "portals" in the south of the basin e.g. the East Carpathian Gate (East Poland), the Silesian Gate (West Poland) and the Burgundian Gate (France). During the Rhaetian stage, new inlets formed in the northwest of the basin through the former highlands in Ireland and Scotland, which came from the Atlantic Ocean which was now opening up.

gollark: Process management stuff got enhanced isolation after a spate of bugs relating to that, so it's *probably* okay now, but there are still problems, inevitably.

gollark: Also, some stuff was deliberately not isolated to the extent it should have been for security - mostly the process management, but possibly some filesystem IO.

gollark: Specifically, it relies on quirkiness in some aspects of Lua to work, but the quirks have more nested quirks attached which have problems.

gollark: Unfortunately, the sandboxing design has always been kind of flaky and inconsistent.

gollark: It incorporates a state-of-the-art-as-of-2018-or-so sandbox designed to stop unprivileged user code from being able to overwrite core OS files, ever.
