E105 Introduction to Minerals
This poster begins by defining a mineral. It then expands on that by exploring
atoms, molecules, and crystal structure. The various crystal structures are
explained. This is followed by an excellent summary of the mineral classes.
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.
