Galena - Wikipedia

Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the cubic crystal system often showing octahedral forms.

SULFUR IN CYRTOLITE AND ITS INDICATION OF GALENA

In the Hybla cyrtolite the lead required to convert all the S into galena is .026 to .O32 which is less than the lead present. Only about .002 of the lead need be thorium lead (ThD), about .007 ordinary lead, and .034 RaG. This would reduce the age to 435 million years.

Lead - Wikipedia

The main lead-bearing mineral is galena (PbS), which is mostly found with zinc ores. Most other lead minerals are related to galena in some way; boulangerite, Pb 5 Sb 4 S 11, is a mixed sulfide derived from galena; anglesite, PbSO 4, is a product of galena oxidation; and cerussite or white lead ore, PbCO 3, is a decomposition product of galena.

Background | Laboratory for Environmental Analytical ...

The magma that carried lead and lead precursor isotopes to the earth's surface cooled into deposits of minerals with high lead concentrations (lead ores). Lead metal is refined from these ores, the most economically useful of which, is galena. This ore contains lead largely as the lead (II) sulfide, PbS, and is recovered by roasting the ore in air.
