WebCleavage: In mineral terms, cleavage describes how a crystal breaks when subject to stress on a particular plane. If part of a crystal breaks due to stress and the broken piece retains a smooth plane or crystal shape, the mineral has cleavage. A mineral that never produces any crystallized fragments when broken off has no cleavage. WebPyrite FeS2 6-6.5 5 Dark grey Brass yellow; tarnishes brown. Cubes or octahedrons Brittle. No cleavage.

WebDescription and Identifying Characteristics. Its yellow color and odor are sulfur’s most distinctive features. Samples of sulfur are very soft (1.5 to 2.5 on the Mohs scale of hardness) and have a low specific gravity, so they feel ‘light’ for their size. Sulfur also melts at a relatively low temperature (108o C) and becomes brittle when ... hauora
