Detailed explanation-1: -TEXTURES Textures of metamorphic rocks fall into two broad groups, FOLIATED and NON-FOLIATED. Foliation is produced in a rock by the parallel alignment of platy minerals (e.g., muscovite, biotite, chlorite), needle-like minerals (e.g., hornblende), or tabular minerals (e.g., feldspars).
Detailed explanation-2: -Gneissic banding is a metamorphic foliation in which visible silicate minerals separate into dark and light bands or lineations. These grains tend to be coarse and often folded. A rock with this texture is called gneiss.
Detailed explanation-3: -Foliation is the metamorphic rock texture in which minerals grains are arranged in bands or planes caused by pressure which may cause the mineral crystals in the rock to realign or regrow to form parallel bands.
