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.

∙ 13y agothey do not have bands. i dont know about crystals... i think that they do.....

∙ 11y agoA 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.

Contrast foliated and nonfoliated metamorphic rocks?
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.
Is it true or false that the texture of a sedimentary rock that does not have minerals arranged in bands is described as nonfoliated?
False. The terms folidated and nonfoliated apply to metamorphic rocks.
A foliated metamorphic rock when crystals?
A foliated metamorphic rock forms when crystals combine and form visible bands
A foliated metamorphic rock forms when crystals .?
A foliated metamorphic rock forms when crystals combine and form visible bands
Is a metamorphic rock with no banding a nonfoliated rock?
Yes, the other type is a foliate rock with bands of minerals.

they have more crystals

heat and pressure
Does nonfoliated rock have distinct layers of bands?
I dov't know
