What else can I help you with?
Is gniess igneous or metamorphic?
Gniess is Metamorphic.
What kind of metamorphic rock has its mineral grains arranged in bands or planes?
Metamorphic rock with mineral grains arranaged in bands or lamellar planes are called foliated metamorphic rocks.
Is gniess metamorphic?
Yes
Gniess and slate are what kind of rock?
Metamorphic.
What are three types of foliated rock?
Metamorphic rocks are catagorized into two main types: foliated and non-foliated. Three examples of foliated metamorphic rocks are gniess, slate and schist. Some non-foliated rocks include marble, amphibolite and quartzite. Generally, metamorphic rock, and the metamorphic processes can be divided into three categories: regional, contact, and cataclastic.
What is an example of metamorphic rocks?
gniess, slate, and quartzite
Is gniess foliated?
Yes. Gneiss is a foliated metamorphic rock.
What is the primary mineral of Gniess?
Gneiss is a metamorphic rock which exhibits foliation (a layered effect). The layers of gneiss are alternating light and dark layers. Usually the lighter layers are rich in quartz and feldspar and the darker layers are rich in biotite mica, hornblende, or tourmaline.
What is five metamorphic rocks?
- Marble - Schist - Gniess - Slate - Quartzite
Why gniess glitters?
because of the minerals that are mixed in with the gniess during the rock cycle(probably at the igneous stage) reflect light off of themselves
Is Gniess common?
Yes, gneiss (note spelling) is very common, one of the major metamorphic rocks.
How does granite form into gniess?
Granite must be exposed to tremendous heat and pressures in order to transform into the metamorphic rock gneiss.
