Metamorphic rocks that do not have distinct layers or bands?
non-foliated.
Metamorphic rocks such as marble and quartzite are said to be what because their mineral grains are not arranged in parallel layers or bands?
Nonfoliated
Metamorphic rocks that don't have layers?
Sedimentary rocks have layers, not metamorphic rocks.
What are the two categories of metamorphic rocks?
Foliated--those exhibiting layering (gneiss, slate, schists), and non-foliated--without layers (marble, quartzite).
A metamorphic rock with visible layers or bands is said to be what?
Visible layers or bands in metamorphic rock is designated as 'foliation' and the rock is said to be 'foliated'.
Metamorphic rocks that do not have distinct layers or bands?
non-foliated.
What is a type of metamorphic rock in which mineral grains recrystallize but do not form layers?
Those would be non-foliated metamorphic rocks, like quartzite and marble.
Metamorphic rocks such as marble and quartzite are said to be what because their mineral grains are not arranged in parallel layers or bands?
Nonfoliated
Metamorphic rocks with no distinct layers or bands are said to be what?
Non-foliated.
What condition produces the distinct layers of flat and elongated minerals in the foliated metamorphic rocks?
High Pressure.
Does quartzite have layers?
I think NO
What is a nonfoliated texture?
A non-foliated rock is a metamorphic rock that does not display a lamellar texture or distinct light and dark banding common to foliated metamorphic rocks. Non-foliated rock includes quartzite, marble, and metabasalt. Non-foliated metamorphic rocks are most often derived from single mineral sedimentary rocks like limestone and quartz sandstone. == == == ==
Do foliated rocks have layers?
Non-foliated metamorphic rocks generally do not have distinct layering.
Metamorphic rocks that don't have layers?
Sedimentary rocks have layers, not metamorphic rocks.
What are the two categories of metamorphic rocks?
Foliated--those exhibiting layering (gneiss, slate, schists), and non-foliated--without layers (marble, quartzite).
Does metamorphic rock have layers?
Not exactly. Some metamorphic rocks have foliation, which can appear similar to the layers of sedimentary rock. Foliation develops from mineral grains being oriented by pressure, rather than the deposition of layers.
What is metamorphic foliation?
Metamorphic foliation is layering in metamorphic rock. The layers can be very thin, or they can be a meter thick,
