Name:
Named by Pliny the Elder in 77-79 from the Greek "galene" meaning "lead ore".
Galena Group.
Galena is the primary ore mineral of lead. Worked for its lead and silver contents (the latter as minute inclusions of various silver sulphosalts) as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantite-tetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces. The crystals are bright when fresh but often tarnish after exposure to air.
The most common weathering products are cerussite and anglesite.

Varieties of Galena
| Bismuth-bearing Galena | |
| Blaubleierz | Galena pseudomorph after pyromorphite (see also plumbeine). Also used for coatings of epitaxial, oriented films of galena on pyromorphite. Literally "blue lead ore". |
| Bleischweif | Old name for very fine-grained galena, usually caused by recrystallisation under tectonic stress. Older spelling is Bleyschweif. "Bleischweif" occasionally appears in discrete ductile shear zones which have been reactivated after the main ore has crystal... |
| Bleispiegel | Slickenslide galena that forms mirror-like, flattish to slightly curved surfaces. Not to be confused with Bleischweif. |
| Galène tricotée | Literally means "knitted galena". The German name is Strickblende when it occurs with colloform sphalerite or Gestrickter Bleiglanz when no colloform sphalerite is present. |
| Gestrickter Bleiglanz | Acicular Galena. Literally means "knitted galena"; a similar designation is Strickblende but that name only can be used when colloform sphalerite is present as well. The French name is "Galène tricotée". |
| Gold-bearing Galena | A gold-bearing variety of galena; probably microscopic or nano-inclusions of gold or gold-bearing minerals in the galena. |
| Johnstonite (of Haidinger) | Possibly galena with a supposed excess of S. Maybe a mixture of Galena, Anglesite and/or Sulphur. |
| Plumbeine | Galena pseudomorphs after pyromorphite (identical to Blaubleierz) - originally thought to be a hexagonal polymorph of galena (A. Breithaupt, 1863: Berg. Hütt. Zeit. 22, 36). |
| Selenium-bearing Galena | A selenium-bearing variety of galena. |
| Silver-bearing Galena | Silver-bearing galena. Usually, the silver is present as tiny inclusions of various silver sulphosalts. |
| Steinmannite | Supposedly a variety of galena with part of the lead replaced with antimony and arsenic. Probably a mixture. Ref: Standard, 2 |
| U-Galena | A variety of Galena containing uranium-derived lead of isotope Pb-206. |

Not fluorescent in UV.
Other Information
Electrical:
Semiconductor - used as a point contact diode in early radio wireless sets.
Thermal Behaviour:
In an open tube, gives sulfurous fumes.
Notes:
Decomposed by strong nitric acid, with the separation of some sulfur and the formation of lead sulfate.
Health Risks:
Contains lead - always wash hands after handling. Avoid inhaling dust when breaking. Do not lick or ingest.
Industrial Uses:
Principal ore of lead. Often contains silver and is a frequent ore of that metal as well.
