The Introduction to Minerals Poster begins by defining a mineral and then explores the relationship of minerals to atoms and molecules. The crystal structure is introduced, followed by informative text and illustrations that introduce all six crystal structure classes. This is followed by an outstanding presentation of the actual mineral classes – natural elements, suflides, sulfates, carbonates, etc. Identification has traditionally been based on the observation of physical properties: hardness, habit, luster, cleavage, specific gravity, color, fluorescence, streak, etc. This poster presents those properties through informative captions, illustrations and carefully selected photographs. The emphasis is on how to use the physical properties for identification. More than 60 common minerals are shown on this poster, making it even more helpful for identification.
