Question

How does a rock formation with a a band of quartz wrapped around it in one direction and another band of quartz wrapped around the rock at a complete 90 degree difference form? Could this be from pole reversal?

Answer 1

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.
