Which rocks contain silicon?
Silicon is commonly found in minerals such as quartz, feldspar, and mica, which are abundant in many types of rocks like granite, sandstone, and shale. These rocks typically contain varying amounts of silicon in their mineral composition.
What is found in common rocks?
minerals
What does intrusive rocks have?
a lot
Is aluminium in igneous rocks?
Yes. Aluminum-based minerals occur in all three of the main rock types, including igneous rocks.
What are the characteristics of a metamorphic rock and how do they differ from other types of rocks?
Metamorphic rocks are formed from existing rocks that have been changed by heat and pressure. They have a layered or banded appearance and often contain minerals like mica or quartz. Unlike igneous rocks, which form from molten material, and sedimentary rocks, which form from sediment, metamorphic rocks have a distinct texture and structure due to their transformation process.
Does mica schist contain silica?
Yes, mica schist does contain silica, as it is a metamorphic rock formed from the alteration of pre-existing rocks rich in silica like clay or sandstone. Silica is one of the main components of mica schist, alongside minerals such as mica, quartz, and feldspar.
What rocks does a gneiss rock contain?
Gneiss contains the minerals mica, quartz, feldspar, amphibole, garnet, and pyroxene.
Which rocks contain silicon?

How can you tell rocks apart from minerals?
Minerals contain one or many types of minerals (copper, gold, zinc) Rocks contain different types of minerals (Granite- Feldspar, Quartz, Mica, Hornblende)
Minerals in igneous rock?
Felsic rocks mostly contain silicates such as feldspars and quartz, mafic rocks are ferrromagnesian, containing mostly pyroxene and olivine, ultramafic rocks only contain pyroxene and olivine, and rocks neither felsic nor mafic mostly contain plagioclase feldspar, biotite mica, and amphibole.
Is mica extrusive?
No. A mineral is not inherently extrusive or intrusive. Mica can be found in intrisive igneous rocks and in metamorphic rocks.
Which is what is a common minerals found in both organic and chemical sedimentary rocks?
Mica and feldspar are usually found in sedimentary rocks
What is found in common rocks?
minerals
The dating method that can be used in some cases on rocks as young as 50000 years old that contain feldspar mica or amphobole is?
potassium-argon
What rocks are shiny and smooth?
mica
Where does mica occur?
volcanic rocks
What 3 minerals do most granitic rocks contain?
Feldspar (the pink one), Quartz (the white one), Biotite (also possibly hornblende) <- the black one
