Objectif To find a concept for an efficient exploration of mineral resources and hydrocarbons in areas with poor quality in reflection seismics.Most important information were obtained by gravity stripping and additional gravimetric modelling. Hercynian and variscian elements occur in the new gravity map while deep seismic reflection work gives new and qualified information about the lower crust.The main results derived from gravimetric, magnetic and seismic data is a conception of the figuration of the north-west german basin which differs from many existing theories. Thus a general way is indicated to explore similar areas which cannot be explored by seismic survey only.On the base of the existing results main emphasis was laid on the combined interpretation of results of different geophysical methods. Modern techniques in geophysical data processing were used on a large scale.In this project a new interpretation of the "gravimetrische reichsaufnahme" has been carried out, whereas the influence of the sediments down to the "zechstein" was approximately eliminated. The results of this interpretation differ from those of the (reichsaufnahme). This might be caused mainly by the geologic conditions beneath the zechstein (lower permian).A basin study was made by a synopsis of gravity and aeromagnetic results, indicating the history of the basin. Modelling of aeromatic results as well as interpretation of deep reflection observations in North-West Germany were used as additional information. More than 60 seismic lines, recorded up to 12 sec. were used.
