The two textures of metamorphic rocks are the Foliate and Non-foliate textures.

Foliation is a descriptive term applied to certain types of metamorphic rocks, so, by definition, Yes, a folate rock is metamorphic.
Yes, the other type is a foliate rock with bands of minerals.
No. Foliation is a texture most often used to describe the banded, platy, or layered appearance of certain metamorphic rocks.
Any rock can undergo metamorphism, be it sedimentary, igneous or even the transformation of one type of metamorphic rock to another.
In order to foliate, rocks must have pressure along one axis and contain minerals with specific growth patterns
Conglomerate is a clastic sedimentary rock that has rounded pebbles included among its clasts. Gneiss is a high-grade foliate metamorphic rock characterized by alternating light and dark bands. It forms from the metamorphism of granite or schist.
Slate
A fossil is the preserved traces of a living organism from the past (plant, animal, etc.). It is generally preserved because of fast burial in an oxygen-poor environment with low heat and pressure. A foliated rock is a metamorphic rock that has gneiss banding as a result of high pressure and temeprature
Low foliate intake in pregnancy is a particular concern since it is highly associated with an increased risk of the foetus developing Spina Bifida.
Foliate has to do with leaves. (Hence the foliage of autumn when the leaves turn different colours.) But there are other and quirky definitions of the word, having to do with the coating of a mirror with a thin layer, or to decorate with a thin layer, or to split into thin, leaf-like layers. check the link for more info: http://www.thefreedictionary.com/foliate
