Petrophysical data and opaque mineralogy of high-grade and retrogressed lithologies: implications for the interpretation of aeromagnetic anomalies in Northern Vestranden, Central Norway

A regional aeromagnetic anomaly centred around Roan, Northern Vestranden, Western Gneiss Region, Central Norway, is caused by the presence of high-grade orthogneisses and metabasites with 1–2 vol% magnetite. Granulites are surrounded, and partly covered by amphibolite-facies rocks, which consist of...
