Aeromagnetic map with colour-shaded relief, set parallel to Matachewan dykes to suppress the dyke signature and emphasize local structure.

As we had seen before, the predominant structural grain of the Superior Province is east-west. The KSZ cuts this trend obliquely in a NE-SW direction for at least 400 km. It is marked by gravity and aeromagnetic anomalies, as we can see in this slide.
Let's switch back to the previous two slides .
