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."
What is a minerloid - give 3 examples?
A mineraloid is a mineral-like substance that does not demonstrate crystallinity. Mineraloids possess chemical compositions that vary beyond the generally accepted ranges for specific minerals.
Is an opal a type of rock?
No, it's a type of silica, and is classed as a mineraloid.
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.
What are 3 examples of ferromagnesian minerals?
Pyrite, Hematite, Augite
What a three examples of mineraloid?
they are obsidian, opal, limonite

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?
What is the difference between a mineral and a mineraloid?
nothing

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).
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.
What is hardness of opal?
Opal is a hydrated amorphous form of silica; its water content may range from 3 to 21% by weight, but is usually between 6 and 10%. Because of its amorphous character, it is classed as a mineraloid, unlike crystalline forms of silica, which are classed as minerals Opal is a hydrated amorphous form of silica; its water content may range from 3 to 21% by weight, but is usually between 6 and 10%.

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.
