Smithsonite,zinc carbonate,is a common secondary mineral in the oxidation zone surrounding zinc deposits worldwide. It occurs in a wide variety of colors,but usually is found as compact banded masses that were deposited from flowing water solutions. Crystals are not common,and are seldom as well developed as the magnificent specimens from Tsumeb,Namibia (South West Africa) | |
