Galena exhibits perfect cleavage, which means it can break along specific planes of weakness in its crystal structure, resulting in smooth, flat surfaces. This property is due to its cubic crystal system and the strong ionic bonds between lead and sulfur atoms. When fractured, galena typically displays a conchoidal fracture, but its cleavage is the most characteristic feature, making it easy to identify. As a primary ore of lead, galena's cleavage plays a critical role in its extraction and processing.
What else can I help you with?
Is shale fracture or cleavage?
the cleavage is Poor
Dose sapphire have a cleavage break or a fracture?
Sapphire has a mixture of both cleavage and fracture characteristics. It has poor cleavage in one direction and conchoidal fracture, which means it breaks with smooth, curved surfaces similar to glass.
Does quart have a cleavage or a fracture?
Quartz has a conchoidal fracture. It does not have a cleavage plane.
Does silver have cleavage or fracture?
Silver has neither cleavage nor fracture because it is malleable and ductile, meaning it can be shaped and stretched without breaking along specific planes like cleavage or irregularly like fracture.
Does chalcopyrite have cleavage?
Chalcopyrite does not have cleavage. It typically exhibits a conchoidal fracture instead of cleavage planes.
Does galena have a cleavage or a fracture?
It has both. It's cleavage is perfect, and it's fracture is sub-conchoidal.
What is galena's fracture?
Galena's fracture is subconchoidal, and its cleavage is cubic. See http://www.minerals.net/mineral/sulfides/galena/galena.htm for a complete chart about galena's properties.
What is galena's cleavage?
Galena's cleavage is cubic.
What is cleavage of Galena?
Cleavage of galena is the tendency of the mineral to break along planes of weakness, resulting in smooth, flat surfaces. Galena exhibits perfect cleavage in three directions at right angles to each other, producing cubic or octahedral shapes. This property is a result of the crystal structure of galena.
Does quartz have cleavage or a fracture?
Quartz does not have cleavage. However, it does have fracture. Its fracture is conchoidal.

Does hematite have fracture or cleavage?
Hematite has a characteristic fracture, meaning it breaks irregularly with rough or jagged edges and no smooth cleavage planes.
