More Information
Non-foliated rocks are typically homogenous and are formed in conditions where pressure is uniform or at high temperatures near igneous intrusions. Examples include marble and quartzite.
Tips
A common mistake is to think that non-foliated rocks are always homogeneous at a small scale—however, they may still have varying textures.
