Why is the mineral opal referred to as a mineraloid?
Opal is an amorphous form of silica related to quartz, a mineraloid form, not a mineral. A mineraloid is a mineral-like substance that does not demonstrate crystallinity.Now you get it?
Is tektite a mineraloid?
No. A tektite is a drop of molten material (a glass) that is formed from the splatter caused when a meteorite hits the earth.
What type of rock is green opal?
An opal is considered to be a mineraloid, meaning that it has all of the properties of a mineral-- solid, inorganic, naturally forming, has a chemical composition-- but does not demonstrate crystallinity. Other examples of mineraloids include obsidian, an amorphous glass (that is not a crystal).
How does opal fit in the rock cycle?
Opal is amorphous mineraloid, occurrence : Sedimentary and secondary from the alteration of high silica igneous extrusive rocks
What is the opals crystals system?
Opal, being amorphous, is not really a mineral but a mineraloid. One of the scientifically accepted standards defining a mineral is that a mineral must have a crystal structure, which opal lacks. Many scientific groups and references, including the acclaimed Dana's System of Mineralogy, categorize Opal together with the "true" minerals. For this reason, Opal -- as well as other amorphous types that fall under the definition of a mineraloid.

What is the difference between a mineral and a mineraloid?
nothing
What a three examples of mineraloid?
they are obsidian, opal, limonite
What is a mi mineraloid?
It is important to distinguish between a mineral and a mineraloid. A mineral is an inorganic, naturally occurring substance that has a characteristic chemical composition, distinctive physical properties, and solid crystalline structure (an order 3 dimensional arrangement of atoms or molecules). If it does not have this solid crystalline structure, it is not a true mineral and is therefore a "mineraloid."
Is an opal a type of rock?
No, it's a type of silica, and is classed as a mineraloid.
What is cinnabar's crystal form?
There really isnt a crystal form. Therefore it is a mineraloid.
Is Fire Opal a rock or a mineral?
Neither. Opal is a mineraloid, as it does not have a sufficiently organized structure to be considered a mineral.
Is tektite a mineraloid?
No. A tektite is a drop of molten material (a glass) that is formed from the splatter caused when a meteorite hits the earth.
What mineral group is turquoise in?
Opals are not truly minerals (because they don't have a crystalline structure), they are in a class called mineraloid. A mineraloid is an amophous, inorganics substance that lacks a crystalline structure, but are mineral in nature. You will find that in many older reference systems, they may well be classed as minerals.

Is Mercury natural or manmade?
It is apparently a mineral but because of it's liquid state it is considered a mineraloid. Minerals are suppose to have a crystal structure which mercury does not have and therefore is classified as a mineraloid.
