Question

Which mineral will scratch fluorite galena and pyroxene

Answer 1

Quartz is a mineral that can scratch fluorite, galena, and pyroxene.

Step-by-step explanation:

The mineral that can scratch fluorite, galena, and pyroxene is quartz.

Quartz is a mineral that has a hardness of 7 on the Mohs scale. The Mohs scale is a scale that ranks minerals based on their hardness, with 1 being the softest and 10 being the hardest. Fluorite has a hardness of 4, galena has a hardness of 2.5, and pyroxene has a hardness of 5-6. Since quartz is harder than all three of these minerals, it can scratch them.

For example, if you were to try to scratch fluorite with quartz, the quartz would leave a mark on the fluorite, but the fluorite would not be able to scratch the quartz.

Answer 2

"Olivine" is the mineral that will scratch fluorite galena and pyroxene.


Olivine is a standout amongst the most widely recognized minerals in the earth, and is a noteworthy rock forming mineral. In spite of this, great examples and extensive precious stones are exceptional and looked for after. Just couple of areas yield expansive cases of this mineral, although little and tiny grains are discovered around the world. Olivine is additionally found in meteorites, and huge grains have been accounted for in a large number of them.
