Introduction to Minerals Poster

The poster begins by defining a mineral and then explores the relationship of minerals to atoms and molecules. The all-important 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.
 
Collectors and students naturally want to identify their specimens. However, specimens of the same mineral can vary greatly, which can make that a difficult task. Identification has traditionally been based on the observation of physical properties: hardness, habit, luster, cleavage, specific gravity, color, fluorescence, streak, etc. The emphasis is on how to use the physical properties for identification.  There are approximately 100 common minerals. Over 60 of them are shown on this poster, making it even more helpful for identification.
