Foliation is a geologic term that is used to describe the appearance of metamorphic rocks. Foliated metamorphic rocks such as gneiss display banding and regrouping of its mineral constituents as a result of enormous pressures and heat. The banding forms perpendicularly to the direction of pressure. The pressure is usually related to tectonic plate collisions. Schist is another type of foliated rock that exhibits thin layering of micaceous minerals, once again due to pressure and heat. The difference between these two types of foliated rock lies in the rock from which they were derived. Non-foliated metamorphic rocks such as quartzite and marble do not display the banding or layering that are present in foliated rocks. This is because their parent rock was usually sedimentary and more pure in mineral composition than the parent rocks of foliated rocks.
The type of rock that can be foliated and/or non-foliated is the Igneous rock.
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.

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.

i think sedimentary rock is foliated :)
