E106 Minerals    This poster shows a whopping 162 specimens, carefully selected to include those most likely to be encountered by the student and collector. Over 20,000 photographs were reviewed to select ones that would best show a diversity of color, habit, luster and crystals. These magnificent minerals are presented by class: native elements, carbonate, sulfates, sulfides, halides, oxides, phosphate, organic and silicates. The silicates are such a large group that the bottom three rows are devoted to them. They are grouped by sub-class, such as nesosilicates, sorosilicates, etc. All of the popular gemstones are shown.
