The following data was acquired at the Xiao Tang Shan Hot Spring Area, North Beijing, China.

The Xiao Tang Shan area of China is known to have geothermal activity concentrated along fault lines, and a Stratagem survey was peformed to verify the location of a known fault exhibiting the geothermal type activity.

The survey consisted of forty (40) stations using 15 metre dipole spacings for a total survey line length of 600 metres. The data was then processed using Stratagem's 1D and 2D inversion software. The resulting X, Y, Z file created by Stratagem's EMAP 2D processing was contoured using Geosoft mapping software and output to a colour printer.

The fault is interpreted to be the more conductive zone, seen in this presentation as the red area. This increased conductivity is probably the result of weathering associated with geothermal activity. Note that the apparent dip of the fault is clearly seen in the cross-section. Also note the offset in similarly resistive structures across the fault, indicating a vertical displacement along the fault line.
