What kind of metamorphic rock has its mineral grains arranged in planes of bands?
Metamorphic rock with mineral grains arranaged in bands or lamellar planes are called foliated metamorphic rocks.

What kind of metamorphic rock has its mineral grains arranged in planes or bands
What does it mean if mineral grains in a metamorphic rock are arranged in bands?
Foliated rock. If you are looking for whether the rock has no bands it is non-foliated.-Anonymous person but very smart ! :)
Is it true that foliated metamorphic rocks have mineral grains that are randomly placed?
No, foliated metamorphic rocks have mineral grains that are aligned in parallel layers or bands due to the pressure and temperature conditions during their formation. This alignment gives foliated rocks their characteristic layered appearance.
Metamorphic rocks such as marble and quartzite are said to be what because their mineral grains are not arranged in parallel layers or bands?
Metamorphic rocks such as marble and quartzite are said to be non-foliated because their mineral grains are not arranged in parallel layers or bands like in foliated rocks such as slate or schist. This lack of alignment gives non-foliated rocks a more uniform texture and appearance.
The banding of what rock results from dark and light mineral grains?
The banding of metamorphic rock, specifically gneiss, results from the segregation of dark and light mineral grains. This occurs due to high-grade metamorphic processes, where intense heat and pressure cause the original minerals to recrystallize and align, creating distinct bands of differing mineral compositions. The lighter bands typically consist of quartz and feldspar, while the darker bands contain biotite, amphibole, or other ferromagnesian minerals. This characteristic banding gives gneiss its striking appearance and is a key feature in identifying the rock.
What type of rock forms when crystals combine and form with visible bands?
The type of rock that forms when crystals combine and create visible bands is called metamorphic rock, specifically a foliated metamorphic rock. An example of this is gneiss, which features alternating layers of different mineral compositions. The banding occurs due to the alignment of mineral grains under pressure and temperature conditions.
What would you look for to determine if a metamorphic rock is foliated?
grains arranged in solid bands.
What is the parallel arrangement of certain mineral grains that gives the rock a striped appearance?
The parallel arrangement of mineral grains in a rock that gives it a striped appearance is called foliation. This typically occurs in metamorphic rocks due to the alignment of minerals under pressure and heat, resulting in distinct bands or stripes. Foliation can provide clues about the rock's history and the direction of metamorphic forces.
A rock whose mineral grains are not formed in bands is called?
Rock
