Foliated Vs Non Foliated

When rock is subject to extreme pressure grains will squish in the y plane of the pressure. It is composed primarily of hornblende amphibole and plagioclase usually with very little quartz the specimen shown above is about two inches five centimeters across.

Metamorphic Rocks Questions What Are Metamorphic Rocks What

Start studying foliated non foliated metamorphic.

Foliated vs non foliated. Foliation describes the texture how the rock looks of metamorphic rocks. Non foliated two easy metamorphic classifications are. It has to do with the way minerals are aligned in a rock.

This causes the minerals in the original rock to reorient themselves with the long and flat minerals aligning perpendicular to the greatest pressure direction. Lectures by walter lewin. Autoplay when autoplay is enabled a suggested video will automatically play next.

The major differences between foliated and nonfoliated metamorphic rocks are in the areas of texture appearance and the type of pressure applied during recrystallization. Foliated metamorphic rocks are formed within the earth s interior under extremely high pressures that are unequal occurring when the pressure is greater in one direction than in the others directed pressure. For the love of physics walter lewin may 16 2011 duration.

Non foliated metamorphic rocks are rocks that have been changed by heat and pressure into rocks with a non layered or banded appearance. Non foliated is when the rocks grains are made randomly in no arranged pattern. This video describes properties of foliated metamorphic rocks.

Physical geology metamorphic rocks foliated rocks and non foliated rocks loading. Amphibolite is a non foliated metamorphic rock that forms through recrystallization under conditions of high viscosity and directed pressure. Learn vocabulary terms and more with flashcards games and other study tools.

The pressure applied to the reforming rock causes the differences in the way the rock looks once recrystallized and determines whether it will be foliated or nonfoliated. Some examples of non foliated metamorphic rocks include quartzite marble amphibolite and hornfels. In subject of metamorphic rocks to be foliated is to have their grains arranged in parallel layers or bands.
