Explanation:

This is not pole reversal. Pole reversal does not control how a rocks are formed, they only align the orientation of magnetic minerals in a cooling rock.

Pole reversals occur when the direction of the magnetic north and south changes.

The rock type with the quartz band oriented perpendicularly from one another must have been formed along a fracture in the rock formation.
Fractures structurally controls how intrusions are formed.
The quartz band must have been a fluid from a magmatic body that crystallizes at the late stage with some other minerals.
Fractures acts as weakness planes in rocks and they are utilized by intrusive bodies to cool.
