What else can I help you with?
What mineral cannot be scratched by another mineral?
A diamond. Actually, a diamond can be scratched my other minerals.
Can fluorite be scratched by a steel nail?
Yes. A steel nail has a Mohs hardness greater than that of fluorite.
What mineral is hard enough to scratch calcite but no hard enough to scratch amphibole?
Fluorite is a mineral that is hard enough to scratch calcite, which has a hardness of 3 on the Mohs scale, as fluorite has a hardness of 4. However, fluorite cannot scratch amphibole, which typically has a hardness ranging from 5 to 6. Thus, fluorite fits the criteria of being harder than calcite but softer than amphibole.
What mineral has no clevage and cannot be scratched with a steel file?
The mineral that has no cleavage and cannot be scratched with a steel file is typically quartz. Quartz is known for its hardness, ranking 7 on the Mohs scale, which means it can only be scratched by harder materials. Its lack of cleavage results in conchoidal fractures, giving it a distinctive break pattern. Other minerals with similar characteristics may include certain varieties of garnet or tourmaline, but quartz is the most commonly referenced.
What of the following minerals can not be scratched by quartz?
The mineral that cannot be scratched by quartz is diamond. Quartz has a hardness of 7 on the Mohs scale, while diamond ranks at 10, making it the hardest known natural material. Therefore, diamond will easily scratch quartz, but quartz cannot scratch diamond. Other minerals that are harder than quartz, such as topaz and corundum, also cannot be scratched by it.
What kind of mineral leaves a greenish-black streak and cannot be scratched by fluorite?
Pyrite
What mineral cannot be scratched by another mineral?
A diamond. Actually, a diamond can be scratched my other minerals.
Can fluorite be scratched by a steel nail?
Yes. A steel nail has a Mohs hardness greater than that of fluorite.
What mineral can only be scratched by one mineral?
Diamond is the hardest mineral and can only be scratched by another diamond.
Is fluorite harder than calcite?
Yes, fluorite is harder than calcite. Fluorite has a hardness of 4 on the Mohs scale, while calcite has a hardness of 3. This means that fluorite can scratch calcite, but calcite cannot scratch fluorite.
What mineral is hard enough to scratch calcite but no hard enough to scratch amphibole?
Fluorite is a mineral that is hard enough to scratch calcite, which has a hardness of 3 on the Mohs scale, as fluorite has a hardness of 4. However, fluorite cannot scratch amphibole, which typically has a hardness ranging from 5 to 6. Thus, fluorite fits the criteria of being harder than calcite but softer than amphibole.
Which mineral ranked the highest hardness?
A diamond is the hardest mineral. A diamond can scratch all other minerals or rocks and cannot be scratched by another mineral or rock except another diamond.
What minerals can a steel knife scratch?
A steel knife can scratch minerals with a hardness lower than that of steel, such as gypsum, calcite, fluorite, and talc. Minerals like quartz, topaz, and corundum are harder than steel and cannot be easily scratched by a steel knife.
What mineral cannot be scratched by anything but quartz?
There is none because diamond is at the top of the scale so it can scratch anything.
Which mineral cannot scratch any mineral by itself?
Talc is the mineral that cannot scratch any mineral by itself. It has a Mohs hardness of 1, making it the softest mineral on the Mohs scale, which means it can be easily scratched by all other minerals.
What mineral can scratch itself but no other mineral can scratch it?
A diamond is the only material that cannot be scratched by any other than itself.
What mineral has no clevage and cannot be scratched with a steel file?
The mineral that has no cleavage and cannot be scratched with a steel file is typically quartz. Quartz is known for its hardness, ranking 7 on the Mohs scale, which means it can only be scratched by harder materials. Its lack of cleavage results in conchoidal fractures, giving it a distinctive break pattern.
