Satellite altitude (400 km) and aeromagnetic anomaly data have been analyzed over the Kiruna, Sweden iron mining district. A nearly circular-well-defined magnetic anomaly (> 9 n T) is located just south of the city of Kiruna, Sweden. Despite the fact that the satellite anomaly is rather simple the geology and genesis of the ore deposit are complex and controversial. This large anomaly has been mathematically modeled by a rectangular (40 by 70 km) block 20 km deep and 20 km thick having a very high magnetization (11 A/m). In addition the regional fracture pattern is located directly over this block model. We propose a relationship between this fracture pattern, the highly magnetic anomalous mass causing the satellite altitude magnetic signature and the iron ore body with the fracture pattern localizing the mineralization.
