Integration of geology with geophysics : Case studies from Svalbard
This is a study where new and old geophysical data together with information found in literature has been integrated to get a better understanding of the geological evolution of Svalbard. The purpose of the study is to acquire and integrate different geophysical data over the Central Spitsbergen Bas...

This is a study where new and old geophysical data together with information found in literature has been integrated to get a better understanding of the geological evolution of Svalbard. The purpose of the study is to acquire and integrate different geophysical data over the Central Spitsbergen Basin (CSB) and across the Billefjorden Fault Zone (BFZ). The integrated data has then been interpreted to identify locations of basins and structural heights. The main goals with this project have been to plan and conduct a field study to acquire magnetic- and gravity data over the study area to constrain basins and major fault zones. Furthermore, the goal was to integrate gravity- and magnetic data together with seismic interpretations and well data, discussing implications of geophysical data and lastly to add new data to the geodata platform Svalbox. During 10 field days 7 gravity profiles were measured over the CSB and over parts of the BFZ, magnetic data was also collected along most of the profiles.
