They have reached up to a magnitude of 31 , which observes 20 times fainter objects .
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>
