Abstract

High quality magnetic data from the Isua Area are available from two airborne surveys flown in 1998. GEUS carried out a regional survey that covers the entire coastal region and a small part of the permanent Ice Cap. Nunaoil A/S carried out a detailed survey of the Isua Area.

The data from the two surveys are presented together with a number of models that are derived from the data. The models are calculated by using three different geophysical modelling techniques:
• Modelling based on the analytical signal and various filtering techniques
• Forward modelling
• Inverse modelling
The models are discussed in relations to other structural information from Isua. The forward modelling involves a tentative kinematic description of structures in the Isua Greenstone Belt.
