apatite will not scratch quartz topaz calcite or corundum
Calcite and aragonite.
calcite
I think quartz
gold
It's not really possible to answer that, as there are so many. It is also dependent on your definition of mineral. Some are quartz, feldspar, and horneblende.
There are more than 4,000 recognized minerals. Examples of minerals include halite, pyrite, hematite, calcite, gold, silver, quartz, feldspar, mica, gypsum, lepidolite, ruby, diamond, topaz, and graphite.
Diamond, graphite, quartz, topaz, calcite, fluorite, dolomite, magnetite, hematite, pyrite...
Calcite crystals will effervesce in vinegar, quartz will not. Quartz will scratch calcite. The opposite is not true. Quartz and calcite have different crystal structures and different specific gravities. The list goes on, but if you are trying to distinguish them, the above should help.
Well the mohs hardness scale, goes upwarda by 1 everytime and diamond (10) being the hardest is Talc Gypsum Calcite Flurite Appatite Fieldspat Quartz Topaz Corundum Diamond
Quartz because its harder than calcite and the quartz in thicker.
halite. quartz has a stronger bond making it harder to pull the atoms apart
apatite will not scratch quartz topaz calcite or corundum
Halite, copper, diamond, calcite, talc, sphalerite, and quartz are but a few very important and economically important minerals.
The major differences between quartz and calcite are hardness and cleavage. Quartz is about twice as hard as calcite. Quartz has little or at least very seldom any sort of obvious cleavage, whereas calcite has excellent and very obvious rhombohedral cleavage.
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
1) The covalent bonds in quartz are much stronger than the ionic bonds in halite. 2) The stronger bonds of quartz make it harder than halite. 3) You can easily scratch halite with a steel knife ,while you cannot scratch quartz.
