What is foliation how does it form?

Answer 1

Foliated rocks are formed by pressure, they are buried deep. Before, minerals are scattered in the rock randomly. After it goes through presure, minerals are squeezed together and line up in rows. This happens deep underground and inside mountains. The rock has the same minerals in it before and after pressure. The texture of these rocks are foliated. Foliated are minerals that are flattened and lined up in layers.

Answer 2

The foliations of metamorphic rock are created by a reorganization of the minerals in the parent rock. The foliations, layers, or bands, are formed at right angles to the direction of the pressure which is causing the foliation.

Answer 3

Foliation happens when a rock is compressed from one direction and partially recrystallizes. This causes crystals of minerals like mica and chlorite to grow perpendicular to the direction of the force, and gives the rock a banded appearance.

Foliation not related to layering, though if a sedimentary rock with the right mineral makeup is metamorphosed, it may take on a foliated appearance. In this case, however, the orientation of the foliation is usually at a different angle than the original layering.

The end result of foliation is that the rock is so heavily compressed that the minerals actually rearrange themselves in response to the pressure being exerted on the rock. Sometimes this even causes reactions that form new minerals. HOPE THAT HELPED! :D

This is how they are formed

Folitation is mineral layering. Usually alternating light and dark.

This is what they are.

Answer 5

• The state of being in leaf.
• Decoration with sculpted or painted foliage.
• Decoration of an opening with cusps and foils, as in Gothic tracery.
• The act, process, or product of forming metal into thin leaf or foil

• The act or process of coating glass with metal foil.

• The process of numbering consecutively the leaves of a book or manuscript

• The leaves so numbered.

• Geology: The layered structure common to metamorphic rocks.

Answer 6

High pressure during metamorphism causes minerals with flat or needle-like crystals to form with their long axes perpendicular to the pressure.
