Behold, the agates which can be considered
prettiest and strangest of any rocks. Basically, agates are made up of
the films of quartz microcrystals which each film/band represents each
wet period/season similar to the tree growth rings but in reversed way.
The impurities such as iron oxide ("rust") provide a wide variety of colors
to the agates. The agates come in a wide variety of forms from amygdaloidals
(gas bubbles in lava) to "Lithophysae ("thundereggs").
Some
unfamiliar terms may will be encountered, so here is the glossary.
