Lonetal area alb

from Wikipedia, the free encyclopedia

The Lonetal -flächealb (Lower Alb) is the natural area 097 of the Swabian Alb in the south-west German stepland .

Natural structure

The Lone Valley Alb is the direct eastern continuation of the Middle Alb . In the north it borders on the natural area Albuch and Härtsfeld and in the south on the Donauried . On the single sheets 1: 200,000 of the geographic survey of the federal institute for regional studies , the Lonetal area alb was further subdivided in the years from 1952 to 1962, with sheet 171 Göppingen designating the main unit as the lower area alb. The area is structured as follows:

  • 097 Lone Valley Alb
    • 097.0 Ulm Alb
      • 097.00 Ulmer surface alb
      • 097.01 Langenauer Mulde
      • 097.02. Altheim-Dettinger level
      • 097.03. Stotzinger surface alb
      • 097.04 Lone Valley
    • 097.1 Bachtal area alb
      • 097.10 Bachtal-Flachalb (in the narrower sense)
      • 097.11 Lower Brenz Valley
      • 097.12 Lower Egautal

It is a plateau sloping from west to east from 640 m to 510 m above sea ​​level with mostly open and wavy shapes. The spatial expansion extends over around 45 kilometers from Dornstadt in the southwest to Wittislingen in the northeast.

geology

The plateau is structured by the deeply cut valleys of the Lone and Brenz . It is essentially formed from bulk limestone. These are partly detached by impermeable limestone layers or are covered by tertiary deposits and, in the southern part, by Quaternary deposits. Loess drifts have improved the deep, weathered loam. Contiguous forests exist particularly in the area of ​​the Lone Valley.

Only a very small part of the Lone Valley Alb is designated as a protected area (effectively 3.82 percent). These are (with overlaps) 3.52% FFH areas , 0.96% bird protection areas and 1.45% nature protection areas .
