Question

The parent rock for this metamorphic rock had flat layers that were folded during metamorphism. Describe a process that could account for how this rigid gneiss was folded without breaking during regional metamorphism. ( Hint : How could you bend a brittle candlestick without breaking it

Answer 1

Foiliation

Step-by-step explanation:

• Metamorphism is the transformation in the existing rock type and means a change in the form when the rocks are subjected to changes in heat and pressure.

• Regional metamorphism is also called dynamic metamorphism and foliation occurs when a rock s shortened along the axis during recrystallization. Such as mica, the foliated rocks is a product of the stress that deforms the rocks along the plane.
