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.
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?

What element is principally responsible for making olivine pyroxene amphibole and biotite dark?
Iron is principally responsible for making olivine, pyroxene, amphibole, and biotite dark in color. Iron impurities in these minerals can give them a dark green, black, or brown coloration.
What is the most common member of the amphibole group?
The most common member of the amphibole group is hornblende. It is a complex inosilicate mineral that is typically dark green to black in color and has a good cleavage and prismatic habit. Hornblende is commonly found in a variety of igneous and metamorphic rocks.
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 silicate mineral forms a double chain silicate structure?
amphibole
What is Obsidians' composition?
potassiun feldspar, quartz, plagioclase feldspar,biotite, and amphibole.
What is a biopyribole?
A biopyribole is any of the rock-forming minerals pyroxene, amphibole, and mica.
