Urban 3D Geology Halle (Saale)

Market-Place City of Halle (Saale)

Market-Place City of Halle (Saale)

The market-place fault of Halle (Saale) is one of the well known geological features of Germany. The fault is indicated by the yellow dashed line crosses the historical market-place with the Market Church and can be traced through the city area. The vertical displacement of the geological layers is about 600 m. The fault can be observed in the subsurface by a Geoscope.

In conjunction with the City administration of Halle (Saale), a digital 3D geological model was constructed for the total city area of 135 km². Consequently, Halle was one of the first cities in Germany to have available an extremely sharp and detailed 3D volume model of its geological subsurface, which cover the whole city area.

The interactive e-Learning Modul shows the subsurface geology of the city area.

The 3D spatial model provides the basics for a future GIS supported information and prognosis system. Innovative use of the spatial model is based on the extremely sharp modelling of the geological subsurface in the city domain with its 135 km² area and the 24 individual rock formations. At the same time the ordering and juxtaposition of the geological layers in the domain provides information on the most important groundwater aquifers and aquitards. Animation...

The basic data for the model are obtained from a network of 32 cross-sections that represent approximately 1600 different borehole cores. The precision of the horizontal resolution of the spatial model is 40 m x 40 m, while the vertical resolution is on the order of cm depending on available core data.

The possible applications lie in the areas of geological and geotechnical recognition of particular locations of interest, of groundwater and environmental protection, as well as for environmental and city planning, and for education and tourism. The example shows the regional distribution of the large Porphyry-Complex in 3D and the neighbouring younger sediments depicted in virtual cross-sections from the high resolution 3D model of Halle.

Completely new interpretation and evaluation possibilities arise from the superposition of information at different depths in the geological subsurface. The possible uses of an interactive device such as a Subsurface Viewer enable the direct investigation of subsurface information. The results can be presented as virtual boreholes, as anticipated vertical and horizontal sections, thematic maps. Animation...

The geological 3D spatial model of the City of Halle (Saale) results from a cooperative effort between the Specialist Group Hydro and Environmental Geology, Martin Luther University, and the City of Halle (Saale). The spatial model was constructed with GIS 3D; the transfer to a Subsurface Viewer was accomplished in cooperation with INSIGHT, Cologne.

Geothermal potential maps have been generated at the base from the geological 3D model of Halle (Saale) for distinct vertical intervals. The maps show the vertical intervals of -20 to -100 m below the ground surface. The subsurface results from the 3d model are corrected by the topographic position for individual observation point. The terrain model shows topographic differences of up to 70 m within the city area. The fig. shows the geological units with a classified geothermal potential at the position of -100 m (A. Blume 2010). [more...]

Example of the combination of 3d geology subsurface mapping results at -20 m below ground surface and conflicting land-use or geotechnical/hydrogeological restrictions for using near surface geothermal energy (A. Blume 2010).
