Foliation metamorphic rocks
WebDec 16, 2014 · Foliation in metamorphic rock is formed by uni- or bi-directional strain, often under high temperature and pressure conditions, that allow laminar deformation along planes of weakness between layers, mineral grains, and molecular bonds. The foliation, often sheet-like planes with altered mineral composition, can often indicate the direction … WebNov 8, 2024 · 1.) a.

WebThe metamorphic rocks that form when quartz and calcite rocks recrystallize are classified according to their composition, not by foliation type. When quartz-rich sandstone is metamorphosed, the result is the metamorphic rock quartzite (Figure 5.8). When limestone is metamorphosed, the result is marble (Figure 5.9). WebFoliation Controls How Rocks Break Foliated metamorphic rocks have elongated crystals that are oriented in a preferred direction. This forms planes of weakness, and …
WebMay 6, 2024 · There are two main types of metamorphic rocks: those that are foliated because they have formed in an environment with either directed pressure or shear stress, and those that are not foliated because they have formed in an environment without directed pressure or relatively near the surface with very little pressure at all.

Usually, this is the result of some physical force and its effect on the growth of minerals. The planar fabric of a foliation typically forms at right angles to the maximum principal stress direction. In sheared zones, however, planar fabric within a rock may not be directly perpendicular to the principal stress direction due to rotation, mass transport, and shortening. f2gz-1700-dWeb2. contact metamorphism creates no-foliated metamorphic rocks. 3.
