When platy materials have a parallel alignment a rock is .?
foliated
What is a metamorphic rock with parallel lines?
Schists are metamorphic rocks with parallel alignment of minerals.
What is a foiliated metamorphic rock?
A foiliated metamorphic rock is a metamorphic rock that has a texture of parallel alignment of mineral grains. Your Welcome...
What does it mean if the rock layers are foliated?
The foliation is caused by the massive force of pressure and high temperature which results from mountain building processes caused by plate collisions. The heat and pressure combine to realign the existing minerals from a random orientation to one of parallel orientation, thus creating the visible lines or platy cleavages found in foliated metamorphic rocks. The lines of foliation are created perpendicularly to the force being applied.
What changes occur in shale during regional metamorphism?
The change is in the alignment of the clay minerals and parallel alignment of micaceous minerals, from the stress of compressional forces. The water content of the shale is reduced, increasing the rock's specific gravity, and the alignment of the minerals results in a slaty cleavage.
When platy materials have a parallel alignment a rock is .?
foliated
What is the parallel alignment of platy grains in a rock called?
The texture of a rock with aligning parallel platy grains is said to exhibit metamorphic foliation.
Is a strong parallel alignment of different mineral bands in a metamorphic rock?
Foliation
What is a metamorphic rock with parallel lines?
Schists are metamorphic rocks with parallel alignment of minerals.
What conditions are required to form parallel alignment of minerals sometimes found in a metamorphic rock?
Heat is one condition that is required to form parallel alignment of minerals sometimes found in a metamorphic rock. The other condition is pressure.
What is a foiliated metamorphic rock?
A foiliated metamorphic rock is a metamorphic rock that has a texture of parallel alignment of mineral grains. Your Welcome...
What is a metamorphic rock that has parallel alignment of mineral grains?
A folliated texture metamorphic rock, like shist.

What are the Features of gneiss rock?
The main characteristic of gneiss is gneissic texture, foliations (banding) caused by the parallel alignment of constituent minerals as a result of heat and pressure.
What changes occur in shale during regional metamorphism?
The change is in the alignment of the clay minerals and parallel alignment of micaceous minerals, from the stress of compressional forces. The water content of the shale is reduced, increasing the rock's specific gravity, and the alignment of the minerals results in a slaty cleavage.
What is graphite schist?
It is a medium-grade metamorphic rock with a preponderance of the platy mineral graphite.
What is a type of metamorphic rock that has parallel layers?
Foliated rock has parallel layers.
