Nonfoliated rock
Yes, a metamorphic rock with no banding is classified as a nonfoliated rock. Nonfoliated rocks do not exhibit the layering or banding commonly seen in foliated rocks due to the recrystallization process they undergo during metamorphism.
Quartzite is a nonfoliated metamorphic rock that is granular and composed mainly of quartz. It forms from the metamorphism of quartz-rich sandstone.
Metamorphic rocks can be identified if the rock is foliated or nonfoliated, foliating type, type of metamorphism (contact/regional), and by probable original rock. :)
Foaliated rock can form in one or two ways. Extreme pressure may cause the mineral crystals in the rock to realign or regrow to form parallel bands. Foaliation also occurs as minerals that have different compositions separate to produce a series of alternation dark and light bands. Most nonfoliated metamorphic rocks share at least one or two main characteristics. First, the original rock that is metamorphosed may contain grains of only one mineral or contains very small amounts of other minerals.
No. But a Sedimentary rock, Organic.

The Process. Both foliated and nonfoliated rocks begin their lives as either sedimentary, igneous or another metamorphic rock. Type of Pressure. If the pressure applied to the recrystallizing rock is unequal, then a foliated rock will form.

sedimentary rock.
* Foliated (banded) - minerals oriented along visible planes * Example: Schist (fine grain) (from slate) * Example: Gneiss (coarse grain) (from a variety of rock, one of which is granite) * Non-foliated (no banding) usually rock of one mineral) * Example: Quartzite (from sandstone - quartz) * Example: Marble (from limestone - calcium carbonate
The most powerful rock type move is either rock wrecker and head smash
Marble is a metamorphic rock that is massive and lacks banding. It forms from the recrystallization of limestone and is composed mostly of the mineral calcite. Marbles are often used in architecture and sculpture due to their aesthetic qualities.
