Description

Assemblage Zone: pegmatite dikes Chemical Composition: S Crystal System: Orthorhombic System Description: Common Name: Sulfur Group Name: Native Elements Chemistry: S Location: unknown Description: Flattish sheet of small yellow crystals on a rock base. PHYSICAL CHARACTERISTICS: Color is a strong yellow color in thick crystals and duller yellow in small crystals to pale yellow in massive or powdery forms. Can also be reddish or greenish yellow with impurities. Luster is vitreous to more often resinous or earthy in massive forms. Transparency is transparent to translucent. Crystal System is orthorhombic; 2/m 2/m 2/m Crystal Habits include mostly massive or powdery forms but well shaped blocky crystals are common. Crystals can be made up of two dipyramids, one with steeper faces than the other, prisms and/or pinacoids in various combinations. Cleavage is very poor in two directions. Fracture is conchoidal. Streak is yellow. Hardness is 2. Specific Gravity is 2.0 - 2.1 (well below average) Associated Minerals are celestite, calcite, aragonite and gypsum. Other Characteristics: odor (see above), poor heat conductivity makes it brittle when heated and can actually crack if held tightly in a person's hand.e. Best Field Indicators are color, odor, heat sensitivity, lack of good cleavage and crystal habit Fracture: Conchoidal Hardness: 2 Gypsum Luster: Resinous Occurrence: Hydrothermic vents Notable Occurrences include Michigan and Ohio, USA; Sicily; Poland and Chil Rock Type: Sedimentary Specific Gravity: 2-2.1 Streak: Whie Variety: Sulfur (spelled sulphur in some countries) can make a very beautiful mineral specimen, and fine quality examples are much sought after. The unmistakable deep yellow color is not matched by any other mineral and the nicely shaped crystal forms of sulfur add to its attractiveness
