Similarly, you may ask, what is a high grade metamorphic rock?Schist and gneiss are produced by medium to high grade metamorphism. Low-grade metamorphic rocks tend to be fine-grained (the newly formed metamorphic mineral grains that is). High-grade metamorphic rocks tend to be coarse-grained. But grain size is also dependent on the grain size of the protolith.Likewise, what is the hardest metamorphic rock? Quartzite Besides, is quartzite a metamorphic rock? Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts.What is a metamorphic grade?Metamorphic grade is a scale denoting the level of pressure and temperature involved in forming a particular metamorphic rock. The scale is based on the first appearance of particular minerals, known as index minerals.
