This poster shows a whopping 162 specimens, carefully selected to include those most likely to be encountered by the student and collector. Photos best show a diversity of color, habit, luster and crystals.
They 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.
