Biotite gneiss could have a number of protoliths (parent rocks), and those protoliths could be igneous or sedimentary; the sedimentary parent rock could be a fine-grained shale, high in biotite composition, or a granitic rock, high in biotite.

What rock does granite form from heat and pressure?
The ONLY rock that Granite forms is the metamorphic rock Gneiss. Granite is the parent rock of Gneiss.
How does gneiss differ from the rock it was formed?
They are both metamorphic rocks. One difference is the rocks they are formed from. Gneiss is formed from Feldspar and Quartz. Gneiss can also contain muscovite, biotite and hornblende. Quartzite is formed from sandstone. Also Gneiss is more intensely foliated than Quartzite. This can be seen in the bands formed in Gneiss, while quartzite has no bands. Pure quartzite is white, while Gneiss is grey or pink, with dark streaks.
What rock does gneiss come from?
Gneiss may come from either granite or schist.
Why is gneiss in earths surface?
Gneiss is a metamorphic rock that is formed when heat and pressure is applied to an igneous or sedimentary rock. The old rock does not melt completely but reorganizes it's minerals to form banks of foliation giving it the light/dark bands. Gneiss is formed when you have a parent rock that is rich in silica. Since most of the continental crust is silica rich, gneiss it a common rock. It is the highest grade of metamorphic rock in the metamorphic sequence. The sequence goes like this: slate - schist - phyllite - rock.
What type of rock has distinct bands?
Folliated Metamorphic Rock. Example is Gneiss (Banded Gneiss)
What is the origin of a gneiss rock?
Gneiss is a metamorphic rock and its parent rock (protolith) could be a granite or schist.
What rock does granite form from heat and pressure?
The ONLY rock that Granite forms is the metamorphic rock Gneiss. Granite is the parent rock of Gneiss.
Is Gneiss a sedimentary metamorphic or igneous rock?
Gneiss is a banded metamorphic rock.
What is a metamorphic rock made from schist?
Gneiss is a metamorphic rock formed when intense heat and/or pressure is applied to it's parent rock schist.
Is an gneiss rock sedimentary rock?
No, gneiss is metamorphic.
What is parent rock of Muscovite schist?
Gneiss is a high grade metamorphic rock, the product of various rock types being exposed to intense pressures and heat under the surface of the Earth. Orthogneiss is a gneiss whose parent rock was igneous, and paragneiss is a gneiss whose parent rock was sedimentary.
Is gneiss a metamorphic sedimentary or igneous?
Gneiss is a banded metamorphic rock.
What group is gneiss in?
A Gneiss is a Metamorphic rock
Is gneiss an example of igneous rock?
No. Gneiss is a metamorphic rock.
Is gneiss an igneous metamorphic or sedimentary rock?
It is a Metamorphic rock
Is gneiss igneous metamorphic or sedimentary rock?
It is a Metamorphic rock
What type of rock is an example of Gneiss?
Gneiss is an example of a metamorphic rock.
