Schistose Structure metamorphic rocks are known as foliated metamorphic rock.
Limestone is the parent of rock of non foliated metamorphic. This is a very old type of rock.
Metamorphic rocks can be identified if the rock is foliated or nonfoliated, foliating type, type of metamorphism (contact/regional), and by probable original rock. :)
In subject of metamorphic rocks, to be foliated is to have their grains arranged in parallel layers or bands. Non foliated is when the rocks' grains are made randomly in no arranged pattern.Reference:Prentice Hall Earth Science 2009
Metamorphic rocks are typically identified by their foliated texture, which means they have layers or bands. They may also show signs of recrystallization due to high pressure and temperature underground. Chemical composition and the presence of specific mineral crystals can also help determine if a rock is metamorphic.
Phyllite is a type of metamorphic rock that forms from the metamorphism of slate. It is characterized by its sheen, fine-grained texture, and foliated structure.

Foliated rock
Limestone is the parent of rock of non foliated metamorphic. This is a very old type of rock.
Metamorphic rock can be either foliated or non-foliated. Foliated metamorphic rocks have layered or banded textures, while non-foliated metamorphic rocks lack these layers and have a more uniform appearance. Examples of foliated metamorphic rocks include schist and gneiss, while examples of non-foliated metamorphic rocks include marble and quartzite.
Foliated rock has parallel layers.
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.
Non-foliated metamorphic rock, such as marble or quartzite, is characterized by the absence of visible layering or banding. The mineral grains in these rocks recrystallize and grow in a uniform manner, without forming distinct layers like in foliated rocks. This type of metamorphism typically occurs under conditions of high pressure and temperature without the presence of directed stress.
help us we dont know
No banding or alignment of a metamorphic rock's minerals would be consider non-foliated.
