Formula: Pb
Native element
Crystal System: Isometric
Specific gravity: 11.37 measured, 11.341 calculated
Hardness: 1½
Streak: Grey
Colour: Grey, but often coated with white hydrocerussite
Environments:
Native lead is a rare mineral of hydrothermal origin, which requires conditions where both oxygen and
sulphur are scarce in order to form
(Ramdohr p337). Galena is the most important ore of lead.
Anglesite and cerussite are other
common lead-bearing minerals.
Localities
At Långban, Filipstad, Värmland county, Sweden, native lead occurs accompanied by manganese oxides in a granular
limestone
(Ramdohr p337).
At the Cheleken Peninsula, Balkan, Turkmenistan (former USSR), native lead has been deposited from hot brines
(Ramdohr p337).
At Franklin, New Jersey, USA, native lead occurs in rhodonite in very fine
lamellar inclusions
(Ramdohr p337).
