Heat, along with applied pressures, either from depth of burial or from tectonic forces on rock.

∙ 15y agoThe banding or layering (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.

Metamorphic rocks that do not have distinct layers or bands?
non-foliated.
Metamorphic rocks in which minerals are NOT aligned within the rock are called?
Metamorphic rocks in which the minerals show no alignment are called non-foliated metamorphic rocks.
What are the two categories of metamorphic rocks?
Foliated--those exhibiting layering (gneiss, slate, schists), and non-foliated--without layers (marble, quartzite).

Texture term for metamorphic rocks that lack layering?
Non-foliated metamorphic rock, like quartzite and marble.
What describes the thin flat layering in most metamorphic rocks?
The thin flat layering found in most metamorphic rocks is called foliation

What are metamorphic rocks with grains arranged randomly said to be?
They are called foliated metamorphic rocks, and are said to exhibit foliation.

Do foliated rocks have layers?
Non-foliated metamorphic rocks generally do not have distinct layering.
Explain the differences between layering in sedimentary rocks and foliation in metamorphic rocks.?
Layering in sedimentary rock is due to seasonal or event based deposition of small rock particles which reflect the environment at the time of deposition. Layering in metamorphic rocks (foliation) is due to the realignment and alteration of minerals from heat and pressure.

Texture term for metamorphic rocks that lack layering?
Non-foliated metamorphic rock, like quartzite and marble.
Rocks that erodes to expose layering is?
Rock that erodes to expose layering is known as sedimentary rock.
Rock with grains arranged in parallel layers?
Foliated rocks, and in particular: * Shale * Schist * Gneiss
