Calc-silicate gneisses simply are marbles with an impure composition, in other words, the ones that contain a high amount of silica, which combine with calcium and magnesium to form piroxenes, anfiboles and olivines as well. It often happens in the metamorphism of plataformal sequences where limestones are present.
What else can I help you with?
is gneiss a silicate rock?
Yes, gneiss is a type of metamorphic rock that typically contains silicate minerals. It is characterized by its banded or foliated appearance, which results from the recrystallization of pre-existing rocks under high temperature and pressure. The mineral composition of gneiss often includes quartz, feldspar, and mica, all of which are silicates.
What type of crystals does gneiss rock have?
Gneiss usually consists of visible crystals of aligned mineral assemblages.
Can you use gneiss to build countertops?
Yes, you can. Gneiss is quite similar to granite.
Why can the composition of gneiss vary but overall texture cannot?
The texture defines the gneiss. If it varies, it's not gneiss. I'm studying the same thing! -8th Grader! :D
Is lithium a silicate or non silicate mineral?
Lithium is a non-silicate mineral. It is typically found in minerals such as spodumene, lepidolite, and petalite, which belong to the silicate mineral group.
What is made of baUxite?
silicate rocks, such as granite, gneiss, basalt, and shale.

Is talcit made up of calc-silicate minerals?
Talcit is a hydrotalcite like compound with the formula Mg6Al2OH16CO3nH2O
What are rocks called with alternating bands of light and dark silicate minerals?
Rocks with alternating bands of light and dark silicate minerals are called gneiss. Gneiss is a metamorphic rock formed under high temperature and pressure conditions, which causes the minerals within it to align in bands or layers.
What did infinitesimal calculus do?
Infintismal calc is the combination of intergral calc and differential calc
What is composed of alterning bands of light and dark silicate minerals?
Gneiss shows such banding. Alternating bands are known to Geologists as Gneissose Banding, and is used to instantly classify the metamorphic rock.
What is a calc?
A calc is an abbreviation for a calculator or a calculation.
Should you take pre-calc or trig before ap calc?
Yes, you should take both pre-calc and trig before ap calc. Both of those course help lay the fundamentals of ap calc.
Are conics a part of calculus?
Mostly in Calc III you deal with them, not so much in Calc II and none in Calc I
What Crustal rocks are made up primarily?
Crustal rocks are primarily made up of silicate minerals such as feldspar, quartz, and mica. These rocks include granite, basalt, and gneiss, and are commonly found in the Earth's crust.
What is after calculus?
Calc 2, then Calc 3, then usually Differential Equations
What group is gneiss in?
A Gneiss is a Metamorphic rock
