Physical properties

Silvery lead-gray with metallic luster and a blocky, cleaved appearance. Mohs hardness 2.5; cubic crystal structure and perfect cubic cleavage; specific gravity about 7.4–7.6.

Formation & geological history

Forms in hydrothermal veins and carbonate-hosted replacement deposits, often with sphalerite and other sulfide minerals. Deposits range from ancient to geologically recent; age depends on locality.

Uses & applications

The principal ore of lead, used in lead-acid batteries, radiation shielding, and some industrial products; attractive specimens are collected, but lead content makes handling hazardous.

Geological facts

Galena’s unusually high density and cubic cleavage are distinctive. Avoid creating dust, wash hands after handling, and keep it away from children.

Field identification & locations

Look for a heavy, metallic-gray specimen that breaks into cubic fragments; common in mining districts worldwide, including the United States, Australia, and Europe. The photo is consistent with a small galena specimen.
