Physical properties

Formation & geological history

If galena-bearing, it likely formed in hydrothermal veins or replacement deposits as mineral-rich fluids cooled; such deposits occur across many geological ages.

Uses & applications

Galena is the principal lead ore, but specimens are mainly kept for collecting. Avoid cutting or grinding suspected lead ore; wash hands after handling.

Geological facts

Galena is unusually dense and commonly shows bright lead-gray surfaces and cubic cleavage.

Field identification & locations

The pictured piece appears metallic and banded, but lighting and scale prevent confident identification; a streak test, hardness test, and specific-gravity measurement would help. Galena occurs worldwide, including major deposits in the United States, Australia, and Europe.
