Question

Which of the following is the cleavage of Galena mineral?

• A. octahedral
• B. cubic
• C. irregular fracture surface
• D. regular fracture surface

Hint:

Cubic cleavage is a property where minerals like Galena split along three mutually perpendicular planes.

Answer 1

The Correct Option is B

In the study of minerals, cleavage refers to the tendency of a mineral to break along flat, even surfaces. It is a characteristic that helps in the identification and classification of minerals. Galena, a lead sulfide mineral, is an important ore of lead and is recognized for its distinctive cleavage properties.

When assessing which type of cleavage Galena exhibits, let's analyze the options:

• Octahedral
• Cubic
• Irregular fracture surface
• Regular fracture surface

The correct answer for the cleavage of Galena mineral is cubic.

This is because Galena cleaves along three perpendicular planes, forming cube-like structures. This characteristic is due to its crystalline structure, which belongs to the isometric system. Cubic cleavage is a diagnostic feature of Galena, making it readily identifiable among mineral specimens.
