Erzgebirge region - model of the earth
crust to 30km depth, based on various geological and geophysical data (refraction-
and reflection seismic profiles, gravity model). The lower units are modelled
based on seismic behaviour (density change). The crust consists of a laminated lower
crustal layer (vp=7
km/s), a middle crustal zone (vp=6.3...6.6 km/s), and an upper crustal zone (vp<6.3 km/s).
Remarkable is the metamorphic core structure with high density in
the area of the Saxon Granulite Massif (yellow elliptic surface), which
is bounded by large shear zones and gives insights about the evolution of this
area during the Variscan orogeny. » use your mouse to move the 3d model below

Top view on coal seams, and regional structural model. This detailed
model -created for the geological survey of Saxony- is the basis for
the solution of current hydraulic and geotechnical problems.
Fluvial channel reservoir model, modeled from 3d seismic and well data. The first picture shows three simulated facies based on well logs and seismic attributes, the second shows one porosity simulation within channel and splay facies. Z-axis exaggerated. (Stratton/Texas)
