The word minerals mean A formal definition of a mineral, as used by geologists would be: A naturally occurring inorganic solid that has a definite chemical composition, and an ordered internal structure. Geologists are able to identify minerals because they have characteristic physical properties.
Precambrian rocks<span> are mostly covered by rock systems of more recent origin, but where visible they commonly display evidence of having been altered by intense </span>metamorphism<span>. Precambrian rocks often occur in shields, which are large areas of relatively low elevation that form parts of continental masses.</span>
