Nickel and Iron
Precambrian rocks contain relatively fewer fossils than rocks from different eras. This may be due to the fact that the rocks from this era were subject to a lot of heat and pressure, or were exposed to erosion.
Ore from eroded and deformed rocks
It's rocks are severely bent and folded.
By using their physical characteristics
NO. 1) Carbon is not a common component of rocks. 2) C14's half life is too short.

Because it was created in the precambrian era...The Candadian Shield was formed in the Precambrian Era.The rocks of the Canadian Shield formed during the Precambrian time.

No. Precambrian rocks are exceptionally rare. That period ended 570 million years ago, and the oldest rocks on the surface of the Earth are in the Laurentian Range, which runs from Southern Quebec down into Texas and Mexico.
How are mafic and felsic igneous rocks different
Precambrian rocks have been so deeply buried that they have changed by heat and pressure. That's a summary about the Precambrian time.

Ores mined from shields...
Igneous rocks can be found in the mountains, which are partially composed of Precambrian plutonic rock.
just rocks and blobs of jelly
