Field Fantastic!

Just back from Mozambique and covered in red dirt - I have only one question for you tonight:
What happens when a Pan-African pegmatitic granite intrudes a mid-crustal shear zone in the middle of the construction of Gondwana?

Answer: one of two things:

Those would be augen formed from entrained feldspar crystals in the intruding magma, or,

Those would be rafts of mylonite floating in a granite.
