Instructions on determining detailed mineral information.
- Detailed mineral information
- This is followed by an excellent summary of the mineral classes
This poster begins by defining a mineral. Expands on that by exploring atoms, molecules, and crystal structure. The various crystal structures are explained.
Mineral collectors and students want to identify their specimens. However, specimens of the same mineral can vary greatly in appearance, which can make that a daunting task. Identification is based on a number of properties.
This poster provides an outstanding introduction to those properties: hardness, habit, luster, cleavage, specific gravity, color, streak, and fluorescence. Illustrations are used to explain principles. Photographs of truly outstanding specimens are used as examples.
