[en] seismis refraction ; generalized reciprocal and phantoming method
[en] The paper presents a case study of a seismic refraction survey in Bernburg, Germany. The interpretation was made using the GRM method and phantoming concept. The aim of the survey was to map the depth of the bed-rock over a distance of 2 km. The survey was divided into five linear profiles ranging from 150 to 640 metres in length. The resulting interpreted sections show substantial variations in velocity (1300 to 4500 m/s) and depth (5 to 18 m) of bed-rock. Correlation with existing boreholes shows that the top of the bed-rock is located with an accuracy of the order of 1 metre.
