Galena

Galena (lead sulfide, PbS)

AI-generated identification · may be incorrect

Likely a small, metallic-gray specimen with bright silvery faces; galena has Mohs hardness 2.5, cubic crystals and perfect cubic cleavage, and is unusually dense (specific gravity about 7.4–7.6).

Physical properties

Likely a small, metallic-gray specimen with bright silvery faces; galena has Mohs hardness 2.5, cubic crystals and perfect cubic cleavage, and is unusually dense (specific gravity about 7.4–7.6).

Formation & geological history

Forms in hydrothermal veins and replacement deposits, often alongside sphalerite, calcite, or quartz; deposits span many geological ages. The image alone cannot establish its identity or age with certainty.

Uses & applications

The principal ore of lead, historically used in batteries, shielding, and other lead products; attractive crystals are collected, though lead-bearing specimens require careful handling.

Geological facts

Galena commonly breaks into shiny cubic fragments and can contain silver. Avoid dust, ingestion, and prolonged hand-to-mouth contact; wash hands after handling.

Field identification & locations

The dark, metallic, blocky appearance is consistent with galena, but image detail is insufficient for confirmation; check its exceptional heft and cubic cleavage, without scratching or breaking it. Found in lead-zinc deposits worldwide.
