These are invariably green, black and, more rarely, blue in color. This general name encompasses rocks that are also referred to as greenschist , Foliated metamorphic rocks such as gneiss, phyllite, schist, and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure.

Metamorphic rocks are subdivided into foliated and nonfoliated varieties and are producing minerals that are typical of either the blueschist or eclogite
no it's foliated. Bituminous coal is considered a sedimentary rock and therefore would not be foliated or non-foliated, terms which are used to describe metamorphic rock. Metamorphic rocks can be either foliated or non- foliated. Quartzite or marble would be non-foliated rocks as they are massive and don't show any strips or parallel lines in the rock.
