Explain how you could use field observations to distinguish between rocks produced by contact metamorphism and regional metamorphism
What will be an ideal response?
Contact metamorphism is associated with heat from igneous intrusions, and produces non-foliated rocks. The highest grade of metamorphism is closest to the heat source.
Regional metamorphism is associated with mountain building and the nearly horizontal normal and shear stresses applied during convergence produces foliation.
