What is the difference between a foliated and non-foliated metamorphic rock give two examples of each? Granofels is a broad term for medium- to coarse-grained metamorphic rocks that do not exhibit any specific foliation. All rights reserved. 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). It is caused by shearing forces (pressures pushing different sections of the rock in different directions), or differential pressure (higher . Foliated metamorphic rocks occurs in a kind of strata, due to segregation of the minerals in the rock into light and dark bands. Basalt is a homogenous igneous rock.

These processes link widely separated sequences in a common history. Foaliation Foliated metamorphic rocks exhibit layers or stripes caused by the elongation and alignment of minerals in the rock as it undergoes metamorphism. The nature of the parent rock controls the types of metamorphic rocks that can form from it under differing metamorphic conditions (temperature, pressure, fluids). Non foliated is when the rocks' grains are made randomly in no arranged pattern.Reference:Prentice Hall Earth Science 2009. Your email address will not be published. Foliates are composed of large amounts of micas and chlorites. The mica crystals are consistently parallel to one another. What determines whether a metamorphic rock is foliated or non-foliated? How is foliated different from non-foliated? Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet. Foliation normally forms when pressure was exerted on a rock from one direction. Foliated rocks are often very easy to distinguish from non-foliated rocks, as the layers are often very distinct. 6 What are two characteristics of non-foliated metamorphic rocks? 1 : composed of or separable into layers a foliated rock. The protolith for quartzite is quartz, and because quartz is stable under high pressure and high temperatures, metamorphism of this rock simply causes the reorganization of its crystals. 1996 - 2023 National Geographic Society.

Hornfels is another non-foliated metamorphic rock that normally forms during contact metamorphism of fine-grained rocks like mudstone or volcanic rocks. Regional metamorphism is a type of metamorphism where rock minerals and texture are changed by heat and pressure over a wide area or region. The texture has to do with the sizes and shapes of mineral grains and other constituents in a rock, and how these sizes and shapes relate to each other. The parent rock that undergoes metamorphism is called the protolith. What Can Cause Metamorphic Rocks to create? The distribution of rocks and landforms can be explained by processes that shape areas covering thousands of kilometers, such as the volcanism, mountain building, and sedimentary basins that accompany converging plates.
