Remanent magnetization is a major component of magnetic anomalies in the Bjerkreim-Sokndal (BKS) layered intrusion, in southwest Norway. The BKS lies in doubly plunging syncline and is composed of 6 mega-cyclic units (MCU) subdivided into a sequence of zones, defined by the presence or absence of certain index minerals (Wilson et al., 1996) which in turn control the magnetic properties of the rocks and the magnetic pattern (McEnroe et al., 1996(McEnroe et al., , 2001. In general, the positive induced anomalies are observed over cumulates dominated by magnetite and Ti-rich ilmenite while negative remanent magnetic anomalies are over hemo-ilmenite rich cumulates (McEnroe et al., 2009). A clear example of the latter is the striking negative anomaly observed on the east limb of the Bjerkreim Lobe at Heskestad, with amplitude of −13,000 nT in a high-resolution helicopter survey acquired at 60 m above topography, and below −30,000 nT in ground magnetic surveys , McEnroe, Skilbrei, et al., 2004.Here, we investigated the fine-scale mineral magnetic properties of a sample from this area. The magnetic response of this sample is completely dominated by remanence. Traditional rock magnetic methods, used to investigate the magnetization in natural rock samples, are bulk measurements resulting from magnetic properties' average contributions from all sources in proximity of the sensor. Scanning magnetic microscopy (SMM) is a high-resolution mapping technique that allows us to characterize magnetic contributions of individual mineral phases (deGroot et al.
