Is amethyst related to rocks and minerals?
Amethyst is the purple variety of quartz. Quartz is Silicon Dioxide SiO2. The color comes from trace elements of manganese/Iron Oxide Fe2O3. To get the best color and best uniform color amethyst is heated.
Igneous rocks are classified based upon their mineral composition and?
And their texture, which can be aphanitic, phaneritic, glassy, or porphyritic. mineral composition and crystal texture
Igneous rocks are classified based upon their what?
Igneous rocks can be classified by their method of formation and by their mineralogy.
Classifications of minerals?
A rock's mineral composition is a determining factor in rock identification.
What is one milk based mineral?
Minerals are not made of milk. Milk is produced by mammals to feed their young. Minerals are naturally produced in the earth. Some examples of minerals include calcite and quartz.
Are quartz and diamonds very soft minerals?
No. Quartz is harder than steel (based on the Mohs scale of mineral hardness), and diamond is THE hardest mineral.

Silica is it an oil based product?
No. Silica, or silicon dioxide, is acquired from common sand. In nature it occurs as the mineral quartz.
Is there a different mineral that can be used if we run out of quartz?
No, there is no substitute for quartz (silicon dioxide) as it has several special properties that no other mineral has (e.g. transparent to both ultraviolet and visible light). However if you are just looking for a different mineral than quartz that can be used as a source of silicon for use in semiconductors and silicone oils and plastics, yes there are other silicon based minerals but they are more complex than quartz is chemically which sometimes makes extracting the silicon more difficult and expensive.

Why cant color alone be used too identify most minerals?
Minerals can change color based on small impurities.
What are metamorphic rocks in?
Metamorphic rocks have really all and any mineral based upon different rocks. However common ones are quartz, mica, and calcium carbonate.

Give three reasons why it is difficult to identify a mineral by its color alone?
A mineral's color may be influenced by inclusions of other elements or minerals, or even exposure to heat, light, and radiation. A more reliable identification based on color would be the streak, or color of the powdered mineral.
Is diamond composed of a single element?
Diamond is composed of carbon -- a single element. Quartz is the second most abundant mineral on earth.Quartz is formed from silicone, in fact silicon-oxygen tetrahedra. Quartz then, is composed of two elements.
