What physical property can be used to distinguish quartz from amphibole?
One physical property that can be used to distinguish quartz from amphibole is hardness. Quartz has a hardness of 7 on the Mohs scale, while amphibole minerals like hornblende have a hardness ranging from 5 to 6. Additionally, quartz typically has a glassy luster, while amphibole minerals have a dull to vitreous luster.
What kind of igneous rocks that are composed of an amphibole and intermediate plagioclase?
Granite and diorite contain both.
What is the chemical composition of amphibole?
Amphiboles are minerals containing mostly silicon, oxygen, iron, and magnesium.
What contains moderate amount of biotite and amphibole and proxene?
A rock containing a moderate amount of biotite, amphibole, and pyroxene could be a diorite. Diorite is an intermediate intrusive igneous rock with a composition between that of granite and gabbro, which typically contains these minerals in varying amounts.
Tremolite is part of what mineral group?
Tremolite is a member of the amphibole mineral group.
What rock contains both amphibole and potassium feldspar?
Granite is a rock containing both amphibole and potassium feldspar.
What is the hardness of Amphibole on the Mohs scale of hardness?
The individual minerals in the Amphibole group are between 5-6 on the Mohs scale.
Amphibole chemical formula?
The Amphibole chemical formula is Mg,Fe,Ca,Na)2-3(Mg,Fe,Al)5(Si,Al)8O22OH2.
What physical property can be used to distinguish quartz from amphibole?
One physical property that can be used to distinguish quartz from amphibole is hardness. Quartz has a hardness of 7 on the Mohs scale, while amphibole minerals like hornblende have a hardness ranging from 5 to 6. Additionally, quartz typically has a glassy luster, while amphibole minerals have a dull to vitreous luster.
What is a double chain silicates?
An Amphibole (eg asbestos).
What is an arfvedsonite?
An arfvedsonite is a rare sodium amphibole mineral.
What is the mineral of andesite?
plagioclase feldspar, pyroxene, horneblende (amphibole)
Can amphibole scratch glass?
No, amphibole minerals typically have a hardness of around 5 to 6 on the Mohs scale, while glass has a hardness of about 5.5. This means that amphibole is not hard enough to scratch glass.
Which mineral is hard enough to scratch calcite but not hard enough to scratch amphibole?
Bsjs
What is an amphibole?
Amphibole is a group of inosilicate minerals that are typically dark-colored and composed of double-chain silicate structures. They are commonly found in metamorphic and igneous rocks, and some types of amphibole, such as hornblende, can also be present in hydrothermal veins. Amphiboles have a variety of physical properties and are known for their long, prismatic crystal shapes.
Which silicate mineral forms a double chain silicate structure?
amphibole
What is Obsidians' composition?
potassiun feldspar, quartz, plagioclase feldspar,biotite, and amphibole.
