Is marble low grade or high grade rock
Did you know?
Marble forms under low grade or high-grade metamorphism, although at the latter it will grow larger, more interlocked crystals that reflect its higher temperature and pressure origins. The parent rock of marble is limestone , although marble typically appears to have more identifiable grains.
