| Abstract: | Geological conditions, observation environment of geomagnetic field, background noise and other electromagnetic environment aspects are tested and analyzed at Yingcheng station. The results showed that Yingcheng geomagnetic station is located in the limestone area, and that the horizontal gradient of the magnetic field is less than or equal to 1 nT/m, and that the electromagnetic background noise is less than or equal to 1 nT.The test results show that, based on borehole lithology analysis, the electromagnetic environment is stable but the soil of the station is affected with strong magnetism. It is suggested the soil magnetism detection work should precede station construction. |
