Northern Harz Boundary Fault

The resin northern border fault, also known as the northern Harz border fault or resin northern edge disorder, is a geological fault on which the composed of Paleozoic rocks and verfaltete during the Variscan orogeny resin adjacent to the northerly Subhercyne pool or the Harz mountains.

The resin North Rim is hercynisch oriented ( WNW-ESE direction) and runs from New Pitcher Hahausen about Langelsheim, Goslar, Bad Harzburg, Ilse Castle and Wernigerode, Blankenburg, Thale, Gernrode into the area of Ballenstedt.

The resin northern border fault, the southern boundary of the North German Basin ( NEDB ), which is part of the Central European Basin ( MDB ), represents a small sub-basins of the North German Basin is the Subhercyne basin, which is also known as the Harz mountains. This sunken since the Permian intracontinental basin evolved from the Variscan foreland basin and took on sediments of the Mesozoic. The basin was formed by crustal stretching or Aufdomung the Moho. During the Cretaceous the basin was concentrated by the Alpidic orogenesis, whereby the resin was lifted.

The resin northern border fault was activated in the Lower Cretaceous, and then the resin was lifted from this disorder. The resin was pushed onto the Mesozoic strata of the Subhercynen pelvis, making the Mesozoic strata steeply asked and were even overturned ( see photo). The most intense phase of uplift occurred in a period of about 2 million years ago from the Middle Anton to Untercampan. The completion of uplift shown by the fact that the rocks of the Upper Cretaceous with a much shallower angle than the incident rocks of the Lower Cretaceous, and these also overlap unconformably in some places. The uplift continues today.

In the western part of the rejection of the resin was lifted at least 5-7 km, which can be estimated on the thickness of the deposited in the Harz foreland rocks of the Mesozoic and Paleozoic rocks of the eroded. The resin was partially pushed through the northern strata of the Mesozoic. The Mesozoic strata were asked steep (70-80 degrees) or even overturned. A good example of this is the Langenberg quarry, but there are in addition many other clues that show the steeply upturned layers. This rocks of the Jurassic are provided steep. In the near Blankenburg and Ballenstedt are steeply Asked rocks of the Cretaceous, which form the Devil's Wall. This is among other things to the Heidelberg sandstone, a silicified ( silicified ) quartz sandstone.

On the whole fault system occur sources that lead to both low mineralized waters and mineral waters. The mineral waters are used for example in Bad Harzburg for the cure and Okertal promoted as mineral water ( mineral water Okertaler GmbH).

The northern edge resin was added to the list of 77 excellent national geotopes 2006.
