Gravity and magnetic data acquisition over a segment of the Møre-Trøndelag Fault Complex
Gravity and magnetic data were acquired in the area of Eidsøra, close to Tingvollfjorden, where different segments of the Møre-Trøndelag Fault Complex are proposed. The new data assist in identifying the fault segments and to gain a better understanding of its subsurface expression. In total 265 new gravity stations were established in an area of 4x4 km, and 14 magnetic profiles were measured. Based on geological information, the magnetic profiles locations were chosen to cross two of the segments of MTFC and a series of anomalies can be observed in the magnetic data. A description of the instruments used in the course of the geophysical fieldwork in 2008 and the processing methods is given. Preliminary results in the form of a new gravity anomaly map and magnetic anomaly profiles are also presented. Tables of gravity observations are provided as an appendix to this report.
