A high metamorphic grade
Rocks composed of parent rock material are known as sedimentary rocks. These rocks form through the accumulation and compaction of sediments derived from the weathering and erosion of pre-existing rocks, including igneous, metamorphic, and other sedimentary rocks. Examples include sandstone, limestone, and shale. Additionally, metamorphic rocks can also originate from parent rocks, but they undergo significant changes due to heat and pressure.
Lack of banding
Parent rocks of metamorphic rocks can include sedimentary rocks, igneous rocks, and other metamorphic rocks. Some common parent rocks are shale, granite, and basalt. The mineral composition and texture of the parent rock influence the characteristics of the resulting metamorphic rock.

grayish i think it just looks like rock
how do rocks differ in shape hardness color texture
Rocks differ due to texture, hardness, color and shape.
Parent rocks of metamorphic rocks can include igneous, sedimentary, or pre-existing metamorphic rocks. These rocks undergo changes in mineralogy and texture due to heat, pressure, and chemical processes without melting, resulting in the formation of metamorphic rocks. Different parent rocks can give rise to different types of metamorphic rocks.

shale
Foliation is a characteristic of some metamorphic rocks.
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.
Residual parent material is the weathered bedrock that is found beneath the soil layer. It is the unconsolidated material from which the soil has developed over time through the process of weathering and erosion.

Limestone does not have a parent rock.
