Minerals can be defined as the solid substances that are found on the earth and might be composed up of either elements or the combination of elements.
Some of the examples of minerals that are commonly found on earth are iron, copper, gold, silver, etc.
The properties that a mineral should possess are that they should be solid, inorganic, naturally occurring and must have definite chemical composition and ordered internal structure.
So, we can say that the organic soil can't be considered as mineral.
