GEOLOGY

Detailed explanation-1: -Dark minerals usually have a greater specific gravity than light coloured minerals, and the same is true of metallic minerals as compared to silicate minerals.

Detailed explanation-2: -noun Geology. any rock-forming mineral that has a specific gravity of less than 2.8 and is generally light in color.

Detailed explanation-3: -Minerals with a specific gravity under 2 are considered light, between 2 and 4.5 average, and greater than 4.5 heavy. Most minerals with a metallic luster are heavy. The specific gravity may slightly vary within a mineral because of impurities present in the minerals structure.

Detailed explanation-4: -Osmium has the highest Specific Gravity among minerals approved by the IMA, ice has the lowest.

Detailed explanation-5: -If a mineral has a high specific gravity it will feel heavier than another mineral of the same size. Gold, for example, has a higher specific gravity than pyrite or “fools’ gold.” Density and specific gravity are sometimes used interchangeably.
