Lead is a naturally occurring element and is a member of Group 14 (IVA) of the periodic table. Natural lead is a mixture of four stable isotopes, 208Pb (51–53%), 206Pb (23.5– −27%), 207Pb (20.5–23%), and 204Pb (1.35–1.5%). Lead isotopes are the stable decay product of three naturally radioactive elements: 206Pb from uranium, 207Pb from actinium, and 208Pb from thorium.

Zinc deficiency - Wikipedia

Zinc deficiency is defined either as insufficient zinc to meet the needs of the body, or as a serum zinc level below the normal range. However, since a decrease in the serum concentration is only detectable after long-term or severe depletion, serum zinc is not a reliable biomarker for zinc status. Common symptoms include increased rates of diarrhea.

POLYMETALLIC VEIN AND REPLACEMENT DEPOSITS .

Polymetallic vein and replacement deposits are characterized by elevated abundances of Pb-Zn±Cu±Au±Ag±Mo±As ± Bi±Sb. In some districts, ore proximal to igneous intrusions is copper and gold rich, and grades laterally (and sometimes vertically) into lead-zinc-silver-rich ore. A distal, manganese-enriched zone is present in some districts.
