The region of Middle Hesse ((ドイツ語:Region Mittelhessen)) is one of three planning regions in the German state of Hesse, alongside North and South Hesse. Its territory is identical with that of the administrative province of Gießen (''Regierungsbezirk Gießen'') and covers the counties of Limburg-Weilburg, Lahn-Dill-Kreis, Gießen, Marburg-Biedenkopf and Vogelsbergkreis. The Middle Hesse Regional Assembly (''Regionalversammlung Mittelhessen''), which decides on the regional plan, currently consists of 31 members chosen by the five counties and the three towns with special status: Gießen, Marburg and Wetzlar. The regional assembly has tasked the governing president (''Regierungspräsident'') with delivering regional management. The Mid-Hesse Regional Management Association (''Regionalmanagementverein MitteHessen'') was founded on 22 January 2003. == Geology and Geography == Middle Hesse is geomorphologically a mix of uplands and valley depressions, originally shaped by volcanism. The valley of the Lahn, including the natural regions of the Upper Lahn Valley, Marburg-Gießen Lahn Valley, Weilburg Lahn Valley region and Limburg Basin, bisects the region down the centre. Of the highlands on both sides of the river valley, only the Vogelsberg (to its left) and the Gladenbach Uplands (to its right) lie entirely within Middle Hesse. Of the others, only the northern part of the Eastern Hintertaunus in the Taunus, the eastern part of the Westerwald, almost to its highest point, and the (south-)east slopes of the Rothaar at the Kalteiche, including the Haincher Heights and Sackpfeife, are actually within Middle Hesse. The western Middle Hesse belongs to the Rhenish Massif and is therefore its oldest part (formed during the Palaeozoic around 300 to 500 million years ago). This, initially single, mountain chain was uplifted again during the Alpine folding and finally took on the morphology visible today: the vulcanites of the Westerwald and its bisection by the rivers Lahn and Dill with raised fault blocks (Dill Basin) like the Limburg Basin that were broken again during the Tertiary. Depositions of loess and the availability of water resulted in its early settlement. The Hintertaunus includes the southern part of the Middle Hessian slate mountains; north of the Lahn is the Tertiary volcanic upland of the Westerwald and, immediately to the east are the Gladenbach Uplands. The red iron deposits of the in thes west of the latter uplands, which include the Lahn-Dill region, which were the prerequisite for the very early establishment of iron and non-ferrous metal mining, owe their formation to the submarine volcanicity of the Upper Devonian. The kaolin-rich clays of limnic-terrestrial sediments were produced by the depositions of the sea that once covered almost the whole of Germany in the Palaeozoic. They formed the raw materials for the early production of pottery and brick ware in the region. Time and again, attempts were made to mine lignite in Middle Hesse; the use of mineral springs from this time e.g. in the Löhnberger Basin or in Selters has clearly been more successful even to date. The West Hesse Highlands adjoin the slate mountains to the east, as far as the West Hesse Depression. During the Palaeozoic (Mesozoic, around 140 to 200 million years ago), the depression filled up with sediment sequences. Of particular mention, in the highlands west of the depression, is the Bunter sandstone, up to 1,000 metres thick, a porous rock, thus not attractive for settlement, which characterises the Burgwald, as well as the Marburg Ridge, the Lahnberge and the northern part of the Upper Hessian Ridge. The low mountains of the Vogelsberg in the east of Middle Hesse, with a basalt surface area of 2,500 km², is the largest contiguous volcanic mountain range in Europe. Long ago the lavas spread out into table-like formations with a basalt thickness of up to 300 metres. In the centre of Middle Hesse lie several basins which are part of the Mediterranean-Mjösen graben (European rift zone): in the south the foothills of the Wetterau rise in the region, enclosing the Gießen Basin and, behind the barrier of the Anterior Vogelsberg, the Amöneburg Basin. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Middle Hesse」の詳細全文を読む スポンサード リンク
