When mineral grains line up in parallel layers the metamorphic rock is?
When mineral grains line up in parallel layers the metamorphic rock is?
11) foliated rocks describes metamorphic rock, such as slate or gneiss, whose mineral grains line up in parallel layers with layers of dark minerals alternating with layers of light minerals.
What are metamorphic rocks that have their grains arranged in parallel layers or bands called?
Metamorphic rocks
| Question | Answer |
|---|---|
| Metamorphic rocks that have their grains arranged in parallel layers or bands are said to be ________________. | Foliated |
| The mineral grains in these rocks are arranged randomly, this rock is called a ____________ rock. | Non-Foliated |
| Granite turns into ____________. | Gneiss |
What are metamorphic rocks with mineral crystals in parallel bands?
Gneiss is a high-grade metamorphic rock composed of coarse minerals arranged in banded layers in which several different types (and colors) of minerals alternate in parallel bands or layers. Platy minerals are present, but non-foliated layers containing feldspar and quartz are also common.
What type of rock is non-foliated metamorphic rock?
Marble, quartzite, and soapstone are examples of non-foliated metamorphic rocks. Marble (left) and quartzite (right) are non-foliated metamorphic rocks.
What is the difference between a foliated and Nonfoliated metamorphic rock?
Foliated rocks are types of metamorphic rock that have parallel bands of grain. Non-foliated rocks are types of metamorphic rock that have no arrangement or bands of grain. Marble is a type of metamorphic rock that originates from limestone.
What are the primary difference between a foliated and Nonfoliated metamorphic rock?
1 Answer. Stephen G. Stefan V. Foliated rocks are formed under a great amount of relatively equal pressure, where as non-foliated rocks are formed under high temperatures.
Why are Micas parallel?
Continued heat and chemical activity completed the clay-to-mica transformation and caused the mica grains to enlarge. Additional directed pressure brought the mica grains into a strong parallel alignment. The result is the rock known as “phyllite”.
How will minerals Orient when a rock is put under normal stress?
How will minerals orient when a rock is put under normal stress? Atoms dissolve, minerals migrate to new locations, and atoms reform. Minerals dissolve, atoms migrate to new locations, and minerals reform. Atoms migrate to new locations, and minerals reform.
Where would you most likely find regional metamorphism?
Most regional metamorphism takes place within continental crust. While rocks can be metamorphosed at depth in most areas, the potential for metamorphism is greatest in the roots of mountain ranges where there is a strong likelihood for burial of relatively young sedimentary rock to great depths.
