mineral
With the mineral (mineral, a mineral to hit in this way), it generally points at a constant mineral matter crystalline material material having the chemical composition to produce in nature formed by geologic action.
There is an exception partly (amber), but the thing included in an artificial crystal and an active creature is removed closely so that it is mentioned as a mineral.
It is necessary to distinguish the minerals such as the hydroxyapatite which, for example, much, is included in calcspar and the aragonite of the shell, the tooth of the Homo sapiens included in the creature which lived as a living body mineral.
In addition, there are both the amorphous substance material and the exception called a mineral (opal).
By the way, it is reference about "the mineral" in the field of food in a pertinence item.
The mineral matter doing to drinking water or food can be called "quality of mineral", but is not "mineral" itself; (the mineral is a solid material).
It points at an animal, a natural object except the plant, and there is the case that is included in a mineral to oil, subsurface water in a wide sense.
However, by the mineralogical documents, there are many cases to define "chemical composition and a solid material having the crystal structure which are constant with mineral matter to produce in nature" as a mineral.
