Specific gravity (SG) is a related measure that geologist’s use to describe the density of a mineral. For the purposes of this course, the specific gravity of a mineral can be described as “low”, “moderate”, or “high”.To do a luster test, you need to clean the surface of the mineral, dry it, take it to good lighting conditions or use a flashlight. Then, rotate your mineral to observe how light reflects from different sides of your mineral sample. Finally, make an assumption about what the mineral’s surface looks like. Step 1.Zinc sulfide occurs as two polymorphs, cubic sphalerite and hexagonal wurtzite. Sphalerite is the stable phase at low temperatures and is a fairly common trace mineral in sulfidic sediments. It forms as a discrete solid phase since Zn is not incorporated to any significant extent within sedimentary pyrite (Luther et al., 1980, Morse, 1994 ).Table_5. CLEAVAGE. The way a mineral breaks is determined by the arrangement of its atoms and the strength of the chemical bonds holding them together. As these properties are unique to the mineral, careful observation can aid in mineral identification. Cleavage: mineral breaks along parallel, flat surfaces (cleavage planes).The Streak Test: Marks, known as "streaks," are produced by scraping mineral specimens across unglazed porcelain plates. On the left, a specimen of pyrite has produced a black streak. On the right, a specimen of rhodochrosite has produced a white streak. Many minerals produce a white streak, and some geologists prefer using a black streak plate ...Sphalerite is the primary ore of zinc, usually associated with the lead ore galena and other sulfide minerals.
