Galena is found in cavities and brecciated (fractured) zones in limestone and chert, as in the extensive Mississippi River valley deposits, where 90 percent of the U.S. production of lead is mined. The mineral has occasionally been observed as a replacement of organic matter and sometimes occurs in coal beds.
Is Galena safe to touch?
Galena is a lead sulphide mineral that is one of the primary ores of lead found around the world. The lead in Galena is toxic if inhaled or ingested from dust particles, but the mineral or rock containing the mineral can be handled safely if there is no lead dust present.
How poisonous is Galena?
The lead in Galena is toxic if inhaled or ingested from dust particles, but the mineral or rock containing the mineral can be handled safely if there is no lead dust present. Hutchinsonite is a form of arsenic sulfide with thallium and lead that can be found in hydrothermal vents.
Is Galena hard to find?
Galena is a lead sulfide mineral with a chemical composition of PbS. It is the world’s primary ore of lead and is mined from a large number of deposits in many countries. It is found in igneous and metamorphic rocks in medium- to low-temperature hydrothermal veins. Galena is very easy to identify.
Is the galena magnetic?
The magnetic state of natural galena is due to a sphalerite impurity: The extrema in the temperature magnetization curve are typical of sphalerite.
What does galena look like?
It has a distinct silver color and a bright metallic luster. Galena tarnishes to a dull gray. Galena is soft with a Mohs hardness of 2.5+ and produces a gray to black streak. Crystals are common and they usually are cubes, octahedrons, or modifications.

What is one unique characteristic of a galena?
Galena is a common and popular mineral for rock hounds. Its characteristic cubes, distinctive cleavage and high density make it easy to identify and a favorite in high school geology labs. The structure of Galena is identical to that of halite, NaCl. The two minerals have the same crystal shapes, symmetry and cleavage.
What is the difference between Galena and lead?
As nouns the difference between galena and lead is that galena is (mineral) a mineral, lead sulphide (pbs), mined as an ore for lead while lead is (uncountable) a heavy, pliable, inelastic metal element, having a bright, bluish color, but easily tarnished; both malleable and ductile, though with little tenacity it is easily fusible, forms alloys with other metals, and is an ingredient of solder and type metal atomic number 82, symbol pb (from latin plumbum ) or lead can be (uncountable) the
