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?
Bsjs
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.
What is the harness of amphibole?
The harness of amphibole, a group of silicate minerals, typically ranges from 5 to 6 on the Mohs scale. This hardness indicates that amphibole is relatively hard and can scratch glass but can be scratched by harder materials. The specific hardness can vary slightly depending on the exact type of amphibole, as there are several different species within this mineral group.
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
Which silicate mineral forms a double chain silicate structure?
amphibole
How would you differentiate amphibole from olivine?
Amphibole and olivine can be differentiated based on their mineral structure and composition. Amphibole is a complex silicate mineral with a double-chain structure, typically containing hydroxyl groups (OH) and exhibiting a range of colors, while olivine is a simple silicate with a single-chain structure, primarily composed of magnesium and iron silicate (Mg, Fe)2SiO4. Additionally, olivine commonly appears green and has a glassy luster, whereas amphibole can exhibit a more varied color palette and often has a more fibrous or prismatic habit. Lastly, amphibole has a lower hardness than olivine, making it easier to scratch.
