All rocks except volcanic or tectonic glasses have crystals. Therefore all metamorphic rocks have crystals, however in lower metamorphic environments these crystals may remain microscopically small.
they do not have bands. i dont know about crystals... i think that they do.....
A metamorphic rock without planar parallel features is non foliated. That said you can still determine XYZ kinematics if it is part of some broader structure.
No, Nonfoliated rocks do.
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.
False. The terms folidated and nonfoliated apply to metamorphic rocks.
A foliated metamorphic rock forms when crystals combine and form visible bands
A foliated metamorphic rock forms when crystals combine and form visible bands
Yes, the other type is a foliate rock with bands of minerals.

Nonfoliated
metamorphic rock.
they have more crystals
non-foliated.
I think its metamorphic
heat and pressure
I dov't know
