What are the ten most rock- forming minerals?
Quartz, Potassium Feldspar, Plagioclase Feldspar, Muscovite (mica), Biotite (mica), Amphibole (hornblende), Pyroxene, Olivine, Calcite, Dolomite.
What minerals make up a rhyolite rock?
The mineral assemblage of Rhyolite is usually quartz, alkali feldspar and plagioclase (in a ratio > 1:2) and biotiteand hornblende are common accessory minerals. More importantly quartz has got to comprise more than 69% of the rock.
What mineral composition is most characteristic of felsic rocks?
felsic is orthoclase, quartz, and biotite. mafic is olivine, pyroxene, and calcium rich plagioclase. I am still researching intermediate.
Which mineral will not scratch quartz topaz calcite or corundum?
apatite will not scratch quartz topaz calcite or corundum
Does Gabbro and granite have a similar mineral composition and texture?
the textures are similar yes but gabbro is made up of calcite and olivine while granite contains biotite mica, feldspar, and quartz.

Quartz, Potassium Feldspar, Plagioclase Feldspar, Muscovite (mica), Biotite (mica), Amphibole (hornblende), Pyroxene, Olivine, Calcite, Dolomite.
The 20 minerals that make up most of the rocks of earth's crust are known as?
olive,pyroxene,amophibole,mica,clay,minerals,feldpards,quartz,calcite,and dolomite
What the most common rock forming minerals are?
Minerals are solid inorganic substances that occurs naturally. Eight of the most common rock forming minerals are quartz, feldspar, mica, amphibole, pyroxene, olivine, kaolinite and muscovite.
What are miner rocks?
Rocks are made of minerals. Only a few minerals are rock forming and most rock is made from a combination of the commonest of these such as feldspars, quartz, mica, olivine, calcite, pyroxene and amphiboles.
What minerals make up a rhyolite rock?
The mineral assemblage of Rhyolite is usually quartz, alkali feldspar and plagioclase (in a ratio > 1:2) and biotiteand hornblende are common accessory minerals. More importantly quartz has got to comprise more than 69% of the rock.

Minerals are solid inorganic substances that occurs naturally. Eight of the most common rock forming minerals are quartz, feldspar, mica, amphibole, pyroxene, olivine, kaolinite and muscovite.
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.
What mineral composition is most characteristic of felsic rocks?
felsic is orthoclase, quartz, and biotite. mafic is olivine, pyroxene, and calcium rich plagioclase. I am still researching intermediate.
Is calcite the most common mineral on earth?
No. Quartz is the most common single mineral.
5 common rock-forming minerals?
It may help to define our terms. A mineral is a substance that has a uniform (definite) chemical composition through out. A rock is a combination of different minerals. There are some typical rocks that have specific mineral content but rocks are not limited to just five minerals. A rock can contain any combination of minerals.
Which would weather faster olivine or quartz?
Olivine would weather faster than quartz
What are the main mineralogical differences between basalts and granites?
Basalts are higher in plagioclase feldspar, pyroxene, olivine and iron content than granites, which are typically higher in quartz, alkali feldspars, and micas.
