Abstract

A gravimetric and a magnetometric survey were performed in Central-Limburg and the surrounding area in the South-eastern part of The Netherlands. A large magnetic anomaly was attributed to a magmatic intrusive. The gravity field in the area is dominated by the effect of the Roervalley graben and the adjacent horsts. After correction for this known geological structures, only a small gravity anomaly remains. This means that the assumed intrusive can't have a high density and, therefore, probably consists of acidic rock. This means that it may, due to the high content of radioactive elements, be at a relatively high temperature. The existence of high temperatures in the past could be proven by analysis of rock samples from the coalmine Sophia Jacoba. For recent high temperatures at depth there are a few indications. The gravity data could also be used to construct a structural map of the area, which is useful to determine the depth of aquifers that can be used for the production of geothermal energy.
