WebMay 6, 2024 · Figure 7.2. 4 Examples of foliated metamorphic rocks: (A) Slate, (B) Phyllite, (C) Schist, (D) Gneiss. If a rock is buried to a great depth and encounters temperatures that are close to its melting point, it may partially melt. The resulting rock, which includes both metamorphosed and igneous material, is known as migmatite (Figure 7.2. 5 ).
WebThe following types of fabric elements can give a rock a foliation. Notice that it’s common for a given foliation to be defined by a combination of fabric elements, as shown in figure 1. Tabular mineral grains: Platy or flake-shaped mineral grains like mica are often aligned to produce a foliation
WebFoliation is defined as a pervasive planar structure that results from the nearly parallel alignment of sheet silicate minerals and/or compositional and mineralogical layering in the rock.
