Biotite is dark mica. Muscovite mica is light in color.
The dark colored mica is called biotite. It is a common mineral found in igneous and metamorphic rocks and is known for its dark brown to black color.
Mica is a transparent mineral that does not have a streak color. It is commonly found in thin, sheet-like layers that reflect light, giving it a shimmering appearance known as luster.

The Mica mineral can change to the mineral group known as amphiboles when Gneiss is formed. This transformation occurs due to the high pressure and temperature conditions during the metamorphic process.
The mineral you are referring to is likely mica, which is known for its characteristic shiny appearance in sheets or layers. Mica is a silicate mineral that is commonly used in arts and crafts, as well as in the electrical and cosmetic industries.

Mica is a mineral that can come in a variety of colors, including silver, black, white, green, red, and purple. Its color is determined by the chemical composition and impurities present in the mineral.
The Mica mineral can change to the mineral group known as amphiboles when Gneiss is formed. This transformation occurs due to the high pressure and temperature conditions during the metamorphic process.
Muscovite (clear) and Biotite (black) are the commonest mica forms. Fuchsite (green) is an unusual mica containing chromium. Please see the related link below for a listing of the mica group of minerals.
