Geological Significance of Gravity and Magnetic Signatures of the Muskox Layered Intrusion, Northwestern Canadian Shield

The Muskox Layered Intrusion is a large Proterozoic (~1270 Ma) differentiated and layered mafic-ultramafic intrusion, which together with its underlying feeder dyke is exposed over a north-south distance of roughly 65 km (Fig. 1). It attains a maximum width of about 10 km at the north end and a thickness of about 2500 m.
