Limburg Basin
structural basin
The Limburg Basin (German: Limburger Becken) is one of the two large intramontane lowland areas within the Rhenish Massif in Germany, the other being the Middle Rhine Basin. It forms the central part of the natural region of the Gießen-Koblenz Lahn Valley between the Weilburg Lahn Valley Region and the Lower Lahn Valley on both sides of the Lahn around the town of Limburg.
Description
The Limburg basin, which measures about 20 by 14 kilometres across and is almost treeless, is a tectonic intrusion field (Einbruchsfeld) and connects the more deeply incised valley sections in the Weilburg Lahn Valley area with those of the Lower Lahn Valley. It is divided into the North and South Limburg Basin Hills and the almost level Inner Limburg Basin, including the Villmar Bay and Linter Plateau, in whose bottom the winding course of the course of the Lahn has sunk about 50 metres deep. The hills that rise at the edges of the basin or within it form landmarks that are visible from a long distance away, dominating the landscape. These include the Heidenhäuschen (397.9 m above sea level (NHN)) north of Steinbach, the Mensfelder Kopf (313.7 m) and the hill ridge of Galgenberg (up to 277.1 m) on the far side of the eastern rim of the basin in the Langhecken Lahn Taunus (in the Eastern Hintertaunus) near Villmar.
The bedrock consists mainly of rocks from the geological Lahn Depression, which outcrop at the edges and on the steep slopes of the valleys. Of particular importance here are three beds of Middle Devonian Corallian Limestone (Lahn Marble) which are embedded in the predominantly volcanic rocks (diabase, schalstein) of the Lahn Depression. In the north, the terrain is shaped by the younger volcanism of the Westerwald with individual basalt deposits - the Galgenberg (241.8 m) at Hadamar, the Großer Berg (245.3 m}) at Ahlbach, the Beselicher Kopf (296 m}) at Obertiefenbach. These are related to tectonic distortions, which pass through the basin in a north–south direction and are recognizable by the Weitungen at Dietkirchen and Limburg as well as by ditch fillings (sand, gravel, clay).
This brief starts where responsible research should: with the source description of “Limburg Basin” as structural basin. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as structural basin. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Nov 3, 2024. The linked authority identifier is Q1000302. VIAF identifies the subject as 239475970. Authority coordinates are 50.380, 8.060. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
